What exhaust did you end up going for on the 3IS? I've been bouncing back and forth between getting TOMS/Fsport one. I already have a plan to swap out the diffuser to one with circular openings so it won't look off.

 

F Sport is an overpriced Invidia Q300, if you want something affordable, nice and with a good sound, look into the Borla 11898.

 

Our most popular one is Apexi, and then we have other options like Ark Performance, Borla, Revel, Invidia etc..

We can get you taken care of.
