Question about quieting the exhaust (really)
Posted April 19, 2003 - 07:57 AM
I bought it with a White Bros E-Series exhaust. But I also got the stock headpipe and muffler on the side.
It appears that there are 7 discs in the muffler now. I have two extras. Would I get any significant lowering of noise with fewer discs? And how many can I go down before losing a lot of power?
Also, how bad (good) is the stock exhaust system for noise and power if the black insert is removed? I assume the screen stays in?
It has supposedly been rejetted for the larger headpipe and muffler, but I assume that it would maybe run a little rich at worst with an unplugged stock exhaust.
I want to do this because an upcoming trip is sort of low performance.

Not sure about the WB system. Stock muffler without the baffle is very loud. With baffle very quiet but no performance. Alot of TTers including myself run stock pipe with an aftermarket baffle. Its a good compromise in sound and performance, most sound test at about 92 db. Costs range from 40.00 to 90.00. Do a search and you will finds lots of info., its been discussed recently. Pipes do effect jetting. With an aftermarket baffle you can run close to stock jetting. Open pipes need richer jetting, more inline with YZF jetting.
