Now I know why this bike is so LOUD...
There are 4 half-inch holes in the left muffler, and 4 in the right. I found the registration of the previous owner & called him. He said he drilled the holes so it'd be louder. It is.

Help! What can I do to plug them?

wait so the guy just grabbed a hole saw and put a buncha holes in the side of the can?

Bahahahahahaahah!

Sounds like a little welding might be in order. Are there not caps in the end of the mufflers? The end of the muffler should be flush with a recessed hole in it. If the entire end of the muffler is recessed then the caps are AWOL (they're held in from the factory by rivets through the outside of the muffler). Also, see my other response (other thread) about the baffle material.

worked, didn't it?

there's not much you really can do save for a new exhaust. there was a company SSS found on Dennis Kirk (i think) that sold aftermarket replacement cans for not a lot of bucks. i think he said a little louder than stock, but he still considered it to be very quiet.

Not the side, the end: around the actual exhaust exit hole.
He just used a hand drill (not well, mind you) w/ a 1/2" bit.
I'll go take a picture. Here:

The picture of the cork... ;D

Ya know, Somtimes I wonder why I hang around this site. I think it's because I never cease to be amazed at the stupid Ideas foisted off onto the poor bike in the name of ????.
They should change the name to Kawawacky.

At some point on the old board, someone mentioned that those chrome trim rings that go around plumbing drains would fit. I never checked, but that might fix you up. If it fits, post a pic. Everybody will want them....

Hmmm.... chrome trim rings from a plumbing store...

Yesterday I went walking around Lowes looking for some stubby fine threaded bolts or some such.
They didn't carry anything fine-threaded & the bolt needs to be a little smaller than 1/2" diameter and maybe 3/4" long. But them I have bolts stuck in the pipe, yuk, but at least the sound would be quieter.

I'll look around & see if any solutions present themselves. Here's hoping...

Anyone have any bright stock mufflers laying around?

Maybe some sheet aluminum cut to size and riveted on the end, I guess thats kinda the same as the chrome rings but gives you the flexibility to make them what ever size you need, I think I'd also seal them some kind of sealant to keep air from escaping between, and making some kind of sound, with my luck it would sound like a steam whistle. If I was going to use bolts (which I wouldn't) I'd pull the baffle and put a nut on the inside.

Wow, that guy did a worse hack job than my p.o. The rings you're looking for are called escutcheons (http://www.plumbingsupply.com/escutch.html). It's going to be a bear finding the perfect size, but there may be a pair out there with your name on them. I've got my end caps off the pipes since my outlet hole is now bigger than the cap's outlet. If you're interested in just replacing those external caps (drill out the three rivets on the outside of the pipe) I could probably send my old ones over. You'll still have holes in the muffler itself, but replacing the cap might make a big difference. And if it's still too loud you could possibly just pack the void between the cap and the internal plate with baffle material (steel wool can work in a pinch) and cut the noise quite a bit.

I'll go take a look at my caps, hug them, say my goodbyes and all that if you want them. When you get a chance, measure the O.D. of the cap itself and I'll measure these to make sure they didn't change something from '90 to '05 (yeah, right ). I can also take pics if need be.

You might just want to try keeping an eye on EBay, too. I saw a brand new stock set of cans about a week ago, bidding low. Today, there's item 250049916320, a set from a '96 in fair shape, bidding for ~$20.

In a car forum I enjoy, one guy was trying make his car as LOUD as possible. So i suggested he hook up a bunch of metal penny-whistles to the exhaust flow. i don't think that's what he had in mind.

I hadn't thought about pulling the baffle before. Hmmmm... let me see here...

That sounds the best value solution yet.
The inside diameter looks like it's right at 4"... though I'm doing a little guess-timating because the cap bulges outwards & won't let me measure straight across.
I'll send a PM.

Reply sent.

And for reference in case it comes up on the forum again, evidently the 1st and 2nd gen caps are the same size. I had assumed the exhaust systems hadn't changed at all, looks like that's the case.

[MrSciTrek]

Mav, If the caps on the end thing doesn't work I'll look at switching the mufflers.
Are yours black or stainless?

 

[maverick9611]

stainless/chrome i will put the pix and asking price in 4 sale section

 

[ex_dsmr]

just for reference, here is a pic i snagged a few days ago of the guy who used the plumbing peices for the end caps. looks pretty nice to me. ive half thought about doing it myself.
