I have been testing a number of quiet exhaust systems which include the following:

1) The stock unit modified.

2) FMF PowerCore IV Q-Series

3) Big Gun Quiet Series

4) E-Series with Quiet Baffle

I will post all the results soon!

I've run out of money so it's gonna be awhile before I get to the T4. They actually make a quiet core for it (but of course that's extra).

It's a good looking and Mega-Lite unit.

Also louder than the E-series (if you can believe it) in stock form!

I was told they discontinued the E series. I tried to order one awhile back.

Do you notice a lot of performance loss with the Baja Designs baffle? What is your top speed with the baffle?
