Size for replacing muffler.

[dan_]

So I want to trade my bike up, i'm looking at an S83. Anyway I want to sell my GZ to get more money then a trade. I wanna replace my dinged up muffler so it doesn't scare people away or bring the price down. Will this beast fit? What size should I be looking for?

Don't worry guys I wont be doing the work myself! My fathers friend owns a fabrication business, builds race cars and stuff he fixed the crack in my exhaust.

Pipe manufacturers should be shot for the lies they tell..........

That fiberglass pipe they show is NOT a real baffle. Even if it would fit, it likely would be LOUD with the so-called baffle in place and REAL loud without it.

Have you posted pics. of your muffler damage before? Are you the one with the little skuff down around the bottom of the muffler?

Unless the damage is large and obvious, you might be better off to leave it alone.......or look for a used OEM one to install. IIRC, replacing the muffler requires some cutting/welding, unless you manage to score a complete set of pipes/muffler.

The damage is large and obvious like.. a big horizontal scrape that screams this bike has slid. The reason I don't want to replace it with a factory muffler is because of how expensive they are. I got a guy who can do the cutting and welding cheap. I just want it to look good so I can sell it quick. If its louder that would probably be a good thing. I live in the country lots of good ol' boys that like loud engines and jacked up trucks. How can I tell if something like this will fit on the GZ? What's a baffle?

It's a toss up. You might get more money by having a shiny muffler, but you'll lose quite a bit by having a poorly running bike. It's just not cost effective. If you absolutely don't want to sell it as is, why not sand it smooth and paint the exhaust?

How is the muffler going to change how the bike runs? I thought all it did was muffle.

[adrianinflorida]

A change in exhaust backpressure affects how the bike runs. The engines are tuned to the intake, exhaust, carb jets, etc. Changes to any of these without adjusting the others to compensate can cause the bike to run like crap.

You change the exhaust and you'll have to rejet the carbs. A more free-flowing exhaust (which ALL non-stock exhausts are, I think) creates a lean fuel/air mixture, and the GZ is set on the lean side from the factory already. You'd have to play around with new jets in your carbs to get an optimal fuel/air ratio. Anything other than optimal will cause the bike to run poorly.

You really DON'T know much about gas engines, do you ? (Retorical question) :??:

THAT is why I suggest that you leave it alone or you are going to make it worth LESS. :skull:

I'm done.

That's not exactly true. I put on an aftermarket exhaust and did not have to rejet. Just a small carb adjustment and i was on my way.




Dan, search the HOW TO forum for everything you need to know about changing mufflers. I did a big write up on it.

Yea, but I'm willing to bet you got an exhaust system designed for your bike, not an aftermarket "universal" exhaust.

Maybe not, since I don't think there ARE any designed for the GZ. I am, however, absolutely sure that HE knew how a muffler works and what a baffle is. :roll:

Yep it was totally universal and not GZ specific.

Oh, you're talking about your GZ? I thought you were talking about the Shadow. In that case, maybe you should point dan_ in the right direction to get the exhaust you did?

[Dupo]

Aren't we on the GZ forum? I wouldn't be referring to my shadow lol.

I did point dan in the right direction in the HOW TO section. I did a write up about how to install aftermarket exhaust.

All is well!
