Exhaust

Hey everyone,

I am looking to make my bike louder.

So I have a question. I do not want to rejet.
If I keep my collector on, and run pipes from there with lollipop baffles, will I need to?

 

Re: Louder Exhaust

If you use google and put site:xjbijes.com after your search terms you can have google mine this forum only. Enter "straight pipe site:xjbikes.com" and read away. The bottom line seems to be some have straight-piped and had no problems without re-jetting, others have experienced a tuning nightmare. If you just want to hear your bike "a bit" more, straight pipes are probably not what you're after.

 

Re: Louder Exhaust

Thanks man. Did that already, for a couple hours before asking gracias.

I am not asking about straight pipes, I am asking about muffler removal while keeping the collector and using a lollipop baffle...

 

Re: Louder Exhaust

A "lollipop baffle" is typically used in a straight pipe. If you remove the mufflers behind the collector box, then run a pipe ending in a lollipop baffle, that's a straight-pipe. If you just put a lollipop baffle in the two ends of the collector box without using any pipes, that's essentially a straight-pipe.

 

Re: Louder Exhaust

Rejetting is nothing to be afraid of. If you're not willing to learn to work on your bike, ride a stock bike and forget about it. If you want certain mods, you're gonna have to put in the work. It's just that simple.

 

Re: Louder Exhaust

Essentially, but not 100% straight pipes...as the collector adds back pressure...I have buddies with straight pipes...generally this means straight from the headers, no collector.

Also, no one said I'm not willing to "learn to work on my bike", so please don't assume. I've put in A LOT of work on my bike. The fact that I don't want to rejet is not a statement of laziness or an unwillingness to "learn to work on my bike"...just an attempt to avoid frustration. I'm sure many of the wizards on here would agree that it is more luck and trial and error than anything.

Sorry for the tone of this response, but perhaps answering someone's question with condescending comments is not the most constructive way to "help".

 

It's not luck. This isn't roulette.

"I wanna change my handlebars, but I don't want to take the grips off".

You want "trial and error"? Put the pipes on and try it. If it works, great, if not you'll have to do what it takes to make it right. I said don't be afraid, I didn't say don't do it. If you've done such a great deal of work to your bike, you should have the skills and confidence to perform the mod. You'll also find some of the "wizards" advise against doing a lot of things here that others have had great success with coughcoughpodscoughcough.

For what its worth...

 

Re: Louder Exhaust

:wink:

 

Still running those pods without rejetting??
How would you know if you haven't done it yet??

Ghost

 

Apples and oranges.

My question was could it or has it been done, and how...basically asking those who have done this before for tips, advice, etc.. Isn't that the purpose of this forum?? I can only imagine if every response on these boards was along the lines of "Do it and see what happens. Ready, fire, aim!" or was loaded with the patronizing garbage I'm getting.

Thanks for the tips though, my question was fully answered. 8O

 

I don't know if anyone has done that mod before or at least I haven't heard of it. Exhaust mods can be a toss up when it comes to needing a re-jet.
Come on, don't be shy, BE THE GUINEA PIG! :lol: Nothing ventured, nothing gained. Let us know what you find out and post some pics.

 

Check out this, maybe it'll help.

Absolutely I am, over 20k without problems. Don't assume.

 

While others have had problems. Sounds like luck to me...which was your whole argument.

 

That's 100% wrong. It's a matter of knowlege, patience and having the correct equipment, not luck. Some have had problems, and others have not. Does that not sound like some people know their sht and some dont? I'm sure you've learned all there is to know about these XJs in your 3 months on this forum. ZZZZZzzzzzzzz Good luck with your louder exhaust.

 

Never claimed to bud. But I can tell you, when someone asks a question that I know the answer to I answer to the best of my ability. If I don't know the answer, I shut the hell up. One thing I don't do is stand on a soapbox and rag on others. Seems like you have learned a lot about interacting with others in your 6 years on the forum.

Guess I forgot the amount of time someone is registered on a website directly correlates to their mechanical knowledge or ability.

I'm done man. But good luck with your complex. 8)

 

Thanks Orange. That actually looks like a good solution. I appreciate it man.

 

Ah what memories come to me, in my youth, I put some loud mufflers on my R90s, didn't have to re-jet, wasn't even aware that it needed it. Anyway I changed by Beemers original sewing machine sound into something that got everybodies attention, including the cops. Good luck finding what you're looking for MisterShah.

 

Inspecting my mufflers and my buddies mufflers, looks like my PO replaced them as mine bolt on and my buddies are welded...I was reading and it sounds like all 650s had the mufflers welded on?

Mine (81 XJ 650):




My friends (80 XJ 650):



Mine are also a bit longer and where his baffle has one center hole, mine has a center hole surrounded by 6 smaller holes. Can I assume mine is aftermarket?

 

I believe all the XJ 650 Maxim exhaust systems have a combination 2-1 collector, crossover connector (to the other muffler) and muffler combined (all welded up). Your PO may have cut off the muffler part and bolted on something else (sounds like it from your description).

Not sure why the desire for "louder" (nor how much louder) - hopefully it's not the "loud pipes saves lives" drivel. If you want it just a little louder you could always drill through the outer baffle through one (or more) of the perimeter holes at the end of your existing muffler.

 

Did you notice in the last post of my thread that Strat didn't have to re-jet with his open pipes? I came up with the muffler idea because the open tips were so loud that small children would run indoors screeming(no joke). :lol:

 

I believe all original exhaust components were welded and aftermaket mufflers were slip on with clamps.

 

No, I don't care much for that adage (saving lives). I just love the sound of loud bikes, and not necessarily just V-Twins. As I said the XJ has a muscle car-esque sound IMO. I don't think I want to mess with my current mufflers, just in case I ever want or need to switch back. Don't know, we'll see where I go with it.

I did notice that Orange! That is a good starting point. I like scaring kids too. HAHA, just kidding. I don't want her to be THAT loud, but loud nonetheless.

 

No, but you said "By the way, sorry if my question sounds a little amateur hour. I am brand new to the bike world, but this is where my heart has always been and I want to do the job right, and well, and be proud of my work. " Your words said you're inexperienced, I just recalled it.

My first reply to you was "dont be afraid to rejet", encouraging you to dig in and learn something you're not familiar with. You said you're "amateur" I was just trying to push you in the direction of learning sht yourself. Sorry for whatever.

 

Well, for starters I said that in a completely different section of the forum in a completely different thread when I first joined (I think it was my third post EVER). I have done quite a bit of research and work on my bike since then. So you recalled that I said that in a different thread several months ago when you first responded in this thread? No. You looked at my post history. Look at my post history some more, and dig into what I have already done. Or at least what I have posted about.

The work I have done may not be a lot compared to some, but based on the work I am proud to have done myself you cannot say that I am unwilling to learn to work on my bike. Yeah, I started working on my first bike only a few months ago. But I have got a lot done and learned a lot in those few months. And I will continue to learn. That is why I am here, asking questions man.

To reiterate why I started this thread: I was asking if I could make the exhaust louder without the need to rejet. I am sure that given enough time and energy, yes I could figure out eventually how to rejet. I don't want to at this time...and if I don't need to to reach my desired result, then hell, I won't!

Examples of a good response to my question: "Yes, you can and here's how:", "Maybe, maybe not", or "No, you will have to rejet."

I honestly appreciate the push for members to learn, and I respect it completely. I appreciate the push to learn, and I make no claims that I know everything about my bike...again, that's why I'm here. But sometimes, just answering the question is sufficient.

 

An update:

Turns out the aftermarket cone mufflers that are on my XJ have removable baffles. I decided to take 'em out and go for a spin.

Loud, but no more loud than my neighbor's Dyna. I like it, but I think I would like to tone it down a notch.

Now, I had a slight popping on deceleration before I removed the baffles that I had been meaning to tune out. Surprise! The popping is still there. :lol: Gonna do some plug chops tomorrow and see if it's tune-able...if not, the baffles go back in for the time being.

Regardless, I hate the way the cones look so I am still going to replace them with something else.

 

seems like a lot of guys like Harley mufflers and i don't think rejetting is required

 

Here's what my bike sounds like without the baffles:

http://smg.photobucket.com/albums/v623/firedeity/?action=view&current=IMG_1160.mp4

A couple of things to note so far: Popping on decel is more pronounced now. Also, idle is about 800 RMPs higher than it was before removing baffles.

Very easy to see that the removal has created a leaner condition. How lean has yet to be determined. Going to check my plugs after my ride home from work.

I really need a colortune though.

 

Check that your exhaust studs are tight, if they're loose (or missing/leaking gaskets) it'll backfire and pop like that. Your carb insulators will cause the same if not snug and sealed up tight. Snug them down, see if it helps. If the condition remains, turn your pilot jets out 1/8 to 1/4 turn. Note what you did so you can return to prior state if it dosen't help or worsens.

How's that for a constructive reply?

 

I like it!! Thanks for the suggestions man!

 

I guess the 700s have welded mufflers as well because I cant get them to budge.

Wanted to try the cheapo turn-downs that Strat and Orange N Black used, but I don't want to go hacking away in case I don't like the end result

what to do...

 

Nope.

According to the fiche, you have a "collector box" system which means the mufflers should unbolt.
