give me advises~~FI vs Stillen

RCZ

Still like the stillen sound the most out of all the exhausts I've heard. It doesn't sound like a tuner car, sounds like the car was meant to sound like this. Performance wise....numbers speak for themselves. I'd still choose the Stillen if I had to choose over again. In fact the only thing I wish is that it were a little louder (even after HFC's). The only thing I would replace it with is longtube headers or something more race-inspired.
