1982 GS750 TZ too loud

[robdsuzuki]

PO put a 4 into 1 Vance and Hines Megaphone on it. I'm used to quiet, stock exhausts. This bike rides fantastic but it just too loud. I hate the loud pipe. Almost tempted to just replace the whole exhaust with something quieter. But first, I guess I should try adding baffle to quiet it down. Is it trial and error - how much packing to add before the jetting is affected? Thanks - Rob

If it's a straight through pipe... add as much as you want.

If you'd rather have a stock exhaust, I'll happily take that awful 4 into 1 and send you the stock exhaust off my 1982 GS750T

I am looking for a stock exhaust. Putting it back on will affect the performance though, correct? I can send you pics of the 4 into 1. Can you do the same for the stock?

[stucknarut]

Sure, will take some and PM you tonight.

As far as performance, I will let someone else answer.

Huh? There is no baffle in the mega phone? If that is the case no wonder it is loud. Get a replacement baffle if you need to and the packing will give it a nice throaty sound with out the loudness. As for the packing, the baffle well only accept a certain about. Don't think the packing will affect the performance per say, just deaden the noise factor. I had once ran mine with the baffle though no packing, the loudness was starting to bother me and no one would ride to my right side lol. I just reinstalled the packing and it made a huge difference in the sound level.

Reinstalling the stock exhaust will affect the performance to a degree, it is more restrictive and heavier then the 4 into 1, probably will have to rejet the carbs.
