Which exhaust is better for a S5 tII.

 

in terms of ultimate flow (and therefore, power), probably the apexi.
if you dont' want to hear this: 'BAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAH' whenever you drive, the RB is the system for you.

 

Very true, there are MANY factors that determine which exhaust is best for the engine (and even more determine if it's right for you). Peak numbers don't mean it's the best powerwise either , search through the forums and stores for some numbers and experiences (as well as sounds and pictures) on each exhaust. My vote goes with Racing Beat setup for the record though .

 

i have the full r/b exast on my 88t2 and i love it it barks as its bitting and she's a church mouse on sunday when i want to be . also the power increase was absolutly awsome they have been doing this a long time r/b and rotarys go together no quetions !!!!

 

i dynoed mine with and without an exhaust, and the rb is about a 3-6hp loss over having nothing at all.
