Exhaust questions

Hey all. Just bought a 1988 750. the p.o. removed the premuffler (goat belly?) and punched out the mufflers. First off, I am going replace the mufflers (this thing is stupid obnoxious loud for me). Any recommendations for mufflers?
Second, will running without the premuffler affect performance in any way?

Thanks.
jeff

Sometimes you can find a complete set of stock exhaust - both sides and the goat's belly - on eBay. Fergy, Beavis, myself and a few others have drilled the end of the stock mufflers. It sounds like a cruiser without being loud. Here's a link for recorded exhaust sounds. The drilled mufflers actually sound throatier.

Yeah, although some say they can't tell the difference. It affects your low end torque.

while tearing my bike apart....I went overboard! I didn't know it til I took off the exhaust, but mine have been punched thru...I still have the goats belly, and set up like that I do not feel it is very loud at all.
you may want to find a goats belly on ebay and install that with your punched pipes, then take it from there to see how you like the sound.

Jeff -

Can't speak to the drilled mufflers as mine are stock. I have removed my pre-muffler and am sure I have lost low end power. Just rode a stock 06' Vulcan and I can feel the difference.

Rather than replacing the pre-muffler, I am going to get an "H" pipe made. This should restore the lost power and make it sound better too.

That'll be after I replace my stator.....

Well, I got some mufflers yesterday at a local bike shop. They almost look like the stock mufflers, with removable baffles.

After I get them on this weekend (my boy's football season is over, so I finally have a free weekend), I'm going to attempt the H pipe.

Thanks

On the stock bike with stock exhaust it is the pre-exhaust chamber of the exhaust system.
Header pipes go into the chamber (goat's belly) which is located underneath the bike and the exhaust and mufflers come out from the goat's belly.
Any aftermarket exhaust systems (not mufflers but full exhaust systems) eliminate the goat's belly.

Stick your head under the bike and look at the blackish-brown tank just forward of the rear tire. It actually tunes the exhaust for more torque. As to not knowing what it is, you're not the only one. Except for the person that named it, there was a time when each one of us didn't know what it was. So your question probably helped a few guests that were/are browsing this thread.
