I have a tanabe super racing medallion right now on my Jackson racing supercharged engine but it is too loud. I am wondering what kind of exhaust will be quiet but still have good flow. I put the silencer in but it cuts performance by a lot. How about the stock rear section with the tanabe b-pipe??, will that be bad on the engine? I was thinking about a Greddy SP or a Apexi World sport, or maybe even the R-SR exhaust.

 

Its up to you, but really you can't get both. Try and find a nice straight through quiet muffler, but i'm not sure the WS is...the Greddy is however. With the SC, it wants less restriction, but that = loud.

 

I have a mugen twin loop , and it is nice an quiet , I tried dropping it and it didn't make any more power. I guess it flows enough.
Hope this gives you an anwser.

 

Check out the exhaust tech section on http://www.team-integra.net

It outlines the differences between aftermarket exhausts on the market as well as which ones use straight through mufflers, n1 style, or restrictive mufflers like the stock one is.
