would like louder pipes, got another ?

is there anything short i of getting new pipes i can do with the stock pipes and mufflers to make them a little louder, maybe a stupid question but id like to herd a little anyway

 

When I had my stock mufflers I took an angle grinder and cut the inside of the muffler out. Basically just connect the four holes with the grinder then pull out that whole inside piece. Sounded much better. Or chop the mufflers off and weld in straight pipe. Thats what I'm running now with no negatives in performance as far as I can tell. Just make sure you support the pipes to the frame.

 

I liked the idea of someone that put the S10 pipes on. Was hoping to have some better shots of how they connected. That sounds SweeeT!

Hate being so Freak'n quiet, I like people to know I'm coming up, or I'm around them... Open Your freak'n EYES! Plus I have a lovely neighbour that needs to hear the bike as much as possible between our houses =)


Ahh Here it is... XJ_Crazy's bike

what if i chop them right behind the rear bracket ,would it make any difference ?

 

I guess you could do that. You mean cut the mufflers in half basically? It might look funny..

 

free and easy.... plus you can make it louder if you want.. You could possibly drill straight down into the muffler and hollow it out more as well


Screams at higher rpm with the pods

 

On mine I originally just connected those three outer holes and the whole piece slides out. The guts of the muffler basically. Not too loud but sounded nice.

 

Ive heard you can pry the sides open and slide the baffles out, if you want to possibly leave it looking stock

If you want to just chop the pipes off, slashcut would be one of the only ways to make it look decent. Ive seen people do what you are talking about.


Hope you dont mind carb tweaking if you change the exhaust. My pods and muffler holes have put me at the very end of adjustment for the 40 pilots... I would imagine a straight exhaust would require bigger pilots and possibly a little bigger main jetting

 

My bike runs better than it ever has with the straight pipes welded where the mufflers were. No re-jetting at all. Then again who's to say it was correct in the first place? I've only cleaned the carbs.

 

on the main jets i believe it... im sure theyre jetted a little overly rich from the factory so it could be perfect now. I know mine would surge after the mods since it was on the edge of being too lean.

With the exhaust im sure you arent insanely lean, just keep an eye on the spark plug color, considering motors will make the most power being overly lean, then melt a piston or detonate.

 

Came from the factory lean (to meat air quality requirements). According to the formula, straight pipes alone result in zero changes to the jets. Adding pods however, frees up the air flow significantly and does cause a change, changing both (like drilling holes) makes an even bigger change.

Find out before permanently doing damage by removing the pipe aft of the collector box. Just leave them off and check out how it runs. A little more pipe on there for looks won't make a hill of beans difference.

 

Schmauster, you must have added more holes since this photo. I saw way more holes when you rode over Sunday.
Pictishusa, I'd do my darnedest to talk someone out of punching out stock, they are getting too scarce. I just picked up a set of Sportster silencers the other day from a guy on craigslist (my thanks to whoever it was that posted that on the forum) for $15 so you might be in luck if you can spend a little time looking around. Good luck!

 

Stamp - any more detail on that bike you posted?

Think it would sound the same with 2 pipes instead of 4? I am thinking of leaving the collector to keep stock jetting - and swapping mufflers for those exhaust tips you can buy @ autozone.

 

Robert,

Too many exhaust fumes im guessing.. this is just how it was when you saw it


I would have to agree with Robert.. I did this when i first got the bike and didnt know how much a good exhaust system can sell for. If you want to go straight pipes then just drop off the back half of the system and save it for if you have to repass inspection because of a noise ticket.

You could probably get some rusted up ones if you plan on cutting the baffles out completely.

Technically the holes are reversible with a welder and some grinding but im sure it wont ever be the same.

 

ok, so sorry robert, i drilled it out then just cut a big circle in it, it's louder but not quite what im looking for yet, think i might do the slah cut right in front of the rear bracket, now whear is that damn cutting wheel?

 

8O youre gonna get me in trouble haha

Just take your slip-ons... off... and then you will have plenty of sound and some mufflers to save.

If you are set on chopping them up.. Open up the back and slide the baffles out.. It will be plenty loud coming out of the megaphones without any baffling. Your neighbor will definately hear you

 

Anybody here with two 'muffler tips' from a car store after the collector?

I really want to know what that would sound like.

What does it sound like with just the two collectors?

 

I bet it would sound like the S-10 turndowns

I would just get 4 mini turn downs, that will sound like a top fuel car and should flow better than the stock collector box.. Youtube has a few videos of this i know


a 4 into 1 with a long 3 inch collector and no muffler would probably be the best for power, but i bet the individual pipes would sound really mean in person.

 

Dpawl- Sent xj_crazy a PM, hopfeully get some more pics and more specs. As far as I can see from the other thread, he's got the headers running down and then 4-9"? extensions, then the S10 turndowns attached to those. Now he's also running pods, so he's been through a rejet hassle.

I'm curios myself if after the collector, you were to run either 2 turndown pipes? (possibly the copper fittings that rdbhere2 used here http://xjbikes.com/Forums/viewtopic/t=1 ... rt=15.html ) attach the single inlet to the collector and then 4 turndowns from that. Save on the rejet but give that more deeper/louder thump or as mentioned the top fuel car tone.

Thinking that might be the way to go.. and then maybe run support hanger from the frame to the turndowns to save on header damage. Not sure if the collector is mounted or free floating under the bike, haven't seen under the bike yet.

 

Hands down, the least restriction will sound the meanest, less things for sound to bounce off of on its way out, no restriction is why the exhaust on the top fuel cars sound so mean... plus the thousands of horsepower helps a little.

Get 2 inch pipes coming out of the head and it would be scary im sure

 

oh ok so what are the S10's HIS BIKE DOES SOUND PRETTY DARN GOOD,

 

Just stole it from his thread..... Click on the images and you get a closer view of how he has it setup... You'll see it's header, then S10 turndowns. Now if there's a collector between or not. I don't know, but I"d have to guess no. So with out the rejet, pods and with collector. I'm sure we'd get a somewhat half decent sound, but without rejetting and running it right from the collector.

 

The best part of living in Kentucky is that if you can sit in or on it and move it down the road it doesnt matter what it looks like, sounds like, or what moves it. No inspections! And I can guarantee there are archaic Harley Davidsons that are louder with mufflers than my XJ with straight pipes! CHOP AWAY!

 

I just carefully and neatly drilled four 5/16 inch holes around the inner stock exhaust outlet, then painted whole end piece black to protect it.

Signficantly improved the sound. Still tolerably quiet at low RPM, but howls nicely up top.

Cost = Free
Time = 10 minutes.

 

Hammerhead, can you post a pic of where you drilled??? I'd love to see that. I like the sound of my XJ, but it needs to be deeper!

 

Hammerhead- Possibly if you could get an audio or vid clip of it, that would be cool as well.

 

SLKid, I'm telling you if you don't mind cutting just use a cutting wheel and basically cut a diamond shape in the end of the muffler, around the center hole. On mine the internals slid right out and it sounded great!

 

Hammerhead, I have to agree, that does sound nice. When I bought mine, the exhaust was drilled out like that. Four holes around the stock outlet and painted black. I thought that's how it came stock, until someone asked me why my bike was so loud!

 

Hey rex, do you got a vid of how your bike sounds?? I'd love some a clip before I start cutting

 

Unfortunately no. The bike has straight pipes now.

 

How far did you cut down?

 

i went low budget on my strait pipes went the the local muffler shop got them to strech a 1 1/2 pipe out to 2 1/2 got them to give me two 24'' peices of scrap 2 1/2 pipe welded the pipe to the reducer snb msde a bracket to hang them sounds real nice and not too loud at rpms

 

ok so i chopped mine right behind the rear bracket at an angle , Damn IT'S LOUD!!!, I THINK PEOPLE WILL HEAR ME NOW!! ARGH!

 

How do you get that chrome plate off at the end of your muffler without tearin it up?? Its got like 6 pop rivets in it. I wanna cut that diamond that Rex is talkin about, but I dont wanna kill that plate

 

You got any pics? possibly vid? or audio to hear what it sounds like?

 

Did someone say louder pipes? I removed everything but the headers and used 1 1/4" pipe fittings to join the head pipes to 1 1/2" X 4' exhaust pipes without baffles. The long pipes give a deep throaty sound. Was pretty cheap to make to.

 

Nice tires on that bike (rest is really cool too)

Should i get a set of white wall tires?

Sorry, somethings just make song lyrics pop into my head.

Return to exhaust discussion...

 

Can someone please explain to me this need for exhausts that are loud(er)?

Loud exhausts, whether on cars or bikes, significantly increase noise pollution, a significant component of stress in our world. Even if *you* like that throbbing base sound, is it fair, is it decent, is it ethical or moral to subject all those in hearing range to it?

You should be looking at ways of making your presence in this world *less* offensive to others, not the reverse.

 

Change "*less*" to *more* and "offensive" to obvious and you will have their safety argument.

Its not about saying "Hey, look at me I'm cool!" but about saying "Hey, look at me, I'm here and you can hurt me by doing the wrong thing".

Why do bike headlight always shine? To make us more obvious.

 

I think there are far superior ways to have other people be aware of you than waking sleeping babies a half mile away ...

 

I try to be very concious of what streets I travel down, and how much Noise (objective word) that I produce. Around here, this thing is like driving a mo-ped.. and you don't want to know how many time's I've seen people cutting/taking out those. Main road just down from me, and this year already, there's been 4 taken out.

When I go down the road, I want people to Know I'm Coming.. Watch where the hell your going and what your doing!

And last but not least, I have a neighbour that is an absolute A$$-Muncher... He Started his bull crap that I can't go between the houses to my Shed out back where I park my bike. I've never ran the bike between the houses or tried to be a nuasecne (sp) in any way. Because an Inch of the handle bars goes over the property line I can't use my shed to park the bike.. So If I have to rip my mufflers off without rejetting then cool.. When the bike warms up I point it's ass between the building and let it idle for 5-10 minutes.. 5 in the morning.. 2 in the morning.. 3 in the afternoon.. whenever I damn well please, and there's Jack he can do about it. So If I can make it louder.. it's one HUge ass Echo chamber between the houses =).. Piss on him and he suck my fumes.

 

You are relying on the senses to have people notice you.

Obviously smell, touch and taste are out.

All that is left is see and hear.

If they can't see you, which 99% of the time is the problem, doesn't matter how many lights, how bright, waving your arms etc... if you are in a blind spot, or around a corner...

THEY WON'T SEE YOU.

Common bumper sticker here in NH (laconia etc) is
LOUD PIPES SAVE LIVES.

They do.

Not saying loud like straight pipe vtwin huge displacement loud.

Saying louder than your average stock exhaust.

A perfect exhaust system is just a hair louder than stock at idle ~ 3k RPM.

But when you are on it, over 3K... time to make some noise.

The waking babies exhaust is ridiculous.

There is a lot of middle-ground.

 

How about, Loud pipes just sound good.
True?
Shoot i'll wake a baby or two up

this whole project i started was for the reason to be able to be noticed a little more easily, im not out to annoy people, im out to help stay alive, as it is the bike is rather small in comparrison to some of the cruisers, but hey if it does annoy someone while im riding then at least i know they herd me, it doesnt hurt that i like the sound too, i dont rip on the revs when im in residential areas, so the sound shouldnt bother anyone except for those over sensitive butt munches who just dont like bikes at all !!!!!!!!!

 

Check out my WWW on the bottom, I had a set of Jardines that the PO gave me. I made custom baffles, i don't think there any pics of it, i took 1 1/4" pipe slit it and pushed the slits in, wrapped it in fiberglass batting and installed. It was too loud so i added more slits and more fiberglass and now it sounds sweet. Not too loud but louder than stock and i can always "tune" my baffles or make new ones, or remove. I did have to re jet, the pilots are now #42 and the mains #114. I just got it back together and did one plug chop and it looks TAN!!!

 

I added three holes around the muffler backplate and I got exactly the results I was looking for, a slightly louder, deeper rumble; nothing too obnoxious, but just enough to be heard. Thanks to schmauster920 for the knowledge.

 

The PO cut the baffles out of my bike, it sounds like a USAC Silver Crown car now, a shade to loud for me. :lol:
But I agree the cagers need to hear us and see us so they dont kill off anymore of us.
A few babies wake up, a small price to pay to save a life I say!

 

haha yup. i love it

 

The biggest problem with the loud pipes save lives argument is you only hear them really loud if they're in front of you...

 

I was just wondering for all you people that have altered their stock exhaust or went straigh pipes or what ever. Did you have to re jet or is every thing still withing tolerance? If it does not require to many changes it might be something I would look into.
