Exhaust baffles on Gl1100

Postby guitarlos » Sat Sep 26, 2009 7:23 am



My bike that I just bought only has one baffle.

Im saving up for a new exhaust.
My question is this......do I just ride it as is or should I tap out the other existing baffle to equalize the pressure until I can get a new set of pipes??
Thoughts?

Yep, you need to remove the other baffle. It's sorta a pain in the arse to get out thou.
I removed both of mine but now I wish I would have keep them in there, sounds like crap to me.

When I get enough cash put away I'm going with the motad system.

ANy suggestion on how to get that existing one out? I was thinking of using a punch around the perimeter to get it out.

Mine already sounds crappy, but I dont want to induce any problems with an unbalanced exhaust.

Thanks much!

There's a rivet at the back of the tailpipe that you drill out and then you pull the baffle out. It may take a couple pry bars or it might come right out.
Mine took the pry bar method.

I think I have a rotted out baffle on my bike as well. I read on the post that they can be removed by drilling out a rivet. Has anyone ever been able to make up a new baffle to install. I would love to keep my original exhaust cause otherwise it is in great shape.

In years past we used to make replacement baffles from stainless steel tubing and drilled and crimped the exaust pathways....worked great.

Would anyone on here have a picture of the baffle?

You can make baffles on the cheap using stainless steel wool, just stuff it in there, but not enough to seriously restrict the exhaust.

Hi I just installed another exhaust system but discovered that one baffle is differant than the onther one. There cover's on them so I wont know what they did till I remove the cover's. I wonder if the exhaust tips that were used on the older air cooled VW type's would work? Something else I noticed is that our 82 goldwing has 49k miles on the clock but has a loud clunk when I shift in or out of gears if this is normal then I guess its alright?

M&T.....If you can post a picture of the baffles from your 82 wing when you get them apart that would be most helpful. Dimensions would be great too. I have exhaust extensions that have to come off first and they are being tempermental. I have an 80 GL1100 parts bike but the exhaust is after market, so it doesn't help me. I want to quiet my bike down...so baffles are the only way.

Thanks Fire guy
I get pics ASAP I do have the exhaust that was on the bike when we got it but the extentions were made for a pickup truck like 3in turndowns that were turned up and out I woulda love'd it if I was 16 again,,LOL LOL but in my book touring bikes dont make good choppers. I do have a set of suzuki cavalcade mufflers I'm thinking about puting then on the old system being that it's rusted out & blown out with bubble gum patch'd welded. The head pipes are still salvagable just a matter of time when I get a chance to to see if that'll work out or not.

I had a hard time finding anyone who stocked stainless steel wool for a packing material for the exhaust baffles. I did find a cheap substitute. I saw in a discount department store stainless steel pot scrubbers that were the same as coarse stainless steel wool....and it was cheap! I'm going to try it, and I'll post how I made out.

I got the Stainless steel wool up the exhaust extension....it did quiet the bike. Unfortunately with no method to secure it in the extentions it blew out on my test ride somewhere..lol.

Best method would be to remove the baffle and re-pack it with the steel wool, then re-install. Anyone out there ever done that before. I would be interested to find out how well it would last.

I just jammed in 1.5 of those pot scrubber stainless steel wool pads into each inlet of my rotted out GL1500 mufflers as well as the cavity between the muffler outlet and the chrome end piece. The result was fantastic! Because I put them in the inlet of the muffler, they don't seem to want to fly out the outlet. They may not be quite as quiet like when they were stock but close enough for me. I can't even hear the engine on the highway now!
