JCWhitney Muffler Mod !!!!!

I really did not like the way my bike sounded. I invested in some CHEAP mufflers from JCW.
I HIGHLY recommend these pipes. They make my XJ sound like a BadAZZ!!!!

EDIT: This is how they sound. http://www.youtube.com/watch?v=26r_cTsGy0w

here it is, I made it for my brother Jimmy earlier

The mod was simple. But it took me most of the day.
My old pipes were welded on so I had to cut them off and whatnot.
This is the page I found the pipes on. These are for the 82 650.
Needless to say, those pipes are not on sale anymore. You have to keep checking or buy something different.

side note for bill- your avatar picture has a bad link or was deleted.

 

Yeah, I worked my ass off trying to get that pic right and then moved the pic in Photobucket. I will try to fix it later when Im tidying up my Photobucket.

 

Nice growl!!!

To bad I now have a parts bike with better-than-mine exhaust/mufflers and no excuse to buy those...

 

P.S. go look at your JC invoice so people know EXACTLY which mufflers you ordered

 

That invoice is long gone. I bought those over a year ago.

I will keep looking for it.

 

That sounds nice. So now that you've given us that one, how about a drive by?

 

ok, give me about an hour or two

 

I'll be looking for it. I called it a drive by, but it's really a fly by, love hearing a bike on full pipe!!!!

 

They do sound really badazz BillB! Thanks for the video!

 

Wow, those sound great, and look even better. I had been planning on doing the sportster muffler mod, but never liked how they stuck out and looked on others I've seen.

Does anyone know what the exact diameter size of the muffler needs to be to bolt-on easily? I assume it would be the same for this 82 maxim as my 82 seca.

 

C-muck,
Those will more than likely come with reducers, so you should be able to make them fit without a problem.
I have a pair of the shorty mufflers that I used on mine for one riding season. They come with different size outlet on each end, so you just turn them around to make them fit. (they're made to fit both ways) They sound just like the ones in BillBs video.
The reason I changed mine for the Sporster mufflers was to keep the hot exhaust from blowing directly at the bottom of my saddlebags. The Sportster mufflers sound pretty close to the same as the shorty mufflers did.
Th JC Whitney mufflers are a good choice for those looking for a better sound and looks, and there are several styles to choose from.

 

Hey Bill,

Is that seat re-covered? Where'd/how'd you get it done? I have two or three of the tall-back ones that need re-covering.

Thanks,

Dave Fox

 

PainterD is right, these did come with a insert as pictured here.
I only know the circumference of the pipes i used. 5 1/2".
The PO welded the megaphones on so I had to cut them off and weld the insert to the manifolds.
BTW, these were not sold as sportster mufflers from JCWhitney.
Actually sportster mufflers may sound different.

 

This seat was purchased from ebay. It was dry rotted and crispy when it landed on my door step from UPS.
I took it down to the upholstery shop and paid way too much to have it covered but I was desperate and he was fast.

 

Its the muffler on the top right on the link VVVVVVVVV
It took some searching but I found the exact mufflers.
This is the link to the mufflers to those that are interested.

Be careful with the mounting tabs on the backside of those JC Whitney mufflers. The bolts on mine were welded on poorly and both broke off when I tightened the mounts. I had to re-weld new bolts onto the back of the mufflers (no big deal, you can't see them anyways) I did burn the chrome around the new bolts when I welded them on, but just a 1/2" or so and it can't be seen when the muflers are on the bike (unless you crawl under the bike and look up!) Just sayin'.

 

Mine have a channel that is welded to the backside of the muffler that accepts the head of the bolt. The tab nuts up to the bolt and tightens fine.

 

Ya some just have that channel that accepts the sliding bolt. It's a much better design and helps make it easier to fabricate the support bracket too. I guess the welded on bolt idea works alright, but they could've welded it better on mine.

 

Is it actually a Maxim seat then? Or just some random seat you made fit? It looks like it belongs there.

 

Some of the wizards may know more but, its called a "king queen" seat.
I bought it from ebay because it was advertised as fitting a yamaha maxim.

 

It is correct for the maxim... it was an option.

I must find one.

 

these are what sportster mufflers sound like

Sportster mufflers on XJ

 

Hrm. Not quite what I was expecting.

Actually, I should go bug that guy at the cycle shop -- he said he was going to scare me up a pair in exchange for doing some onsite computer tech work.

 

btw, those rusty ends on my muffles are screamin eagles baffles. They fit perfectly into the sportster muffler and give you good back pressure if all the fins are out.

 

Sounds similar to mine. Im sure the audio didn't do it justice.

 

Stock Sportster are not that loud at least not on my 1100.

 

Your right, Sposrtster mufflers don't have that bark to them like in the video.

 

There was a disclaimer sticker on my new muffler that reads to the effect. Not approved for bikes after 1983 year due to noise levels or something like that.
Weird huh?

 

BillB:

I have a question for you. I ordered the sporster mufflers from jc whitney and when taking off the old stock mufflers that are rusted/cracked did you just weld the new mufflers on to the crossover pipe or did you clamp them?

Did they match up with the correct angle as the stockers or what adjustments did you have to make to make them the correct angle as the stock ones uset to be?

thanks

 

The PO did me no favors and had welded the original mufflers to the pipes so, it was a cut and paste job (the new pipes have the slip on insert held inside with a clamp).
I was careful to set up the old pipes on my bench and block it up with wood to get the angle close. I wanted the angle be a little less because Im thinking about getting some saddle bags.

 

Mine angle outward a little and are low enough to clear the saddlebags.

 

Staring down a double barrel. Great place for a signal location too.

 

I was going to mount the signals up toward the top of the license plate, but they would rub on the back of the saddlebags, so that's where they ended up.

 

Awesome!! Thank you for the video... I have been lookin at the Turned Out ones for a while for when my bike is ready... I am sold!! =)

Peace
