I helped put one on Zpirates car a few weeks ago... He's a Borla fan and has one on his 350. H-pipe design, sounds good. A little higher pitched than my Stillen, but he likes it a lot. The slip fit joints were a little bit of a PITA (he bought it used) but we got it on. Just a warning though, the pipes hang a bit low..Seems as low as the FI system. If the car is dropped it could be a problem..
Sounds good going down the street but I haven't driven the car with it installed..
