I run the summit racing straight throughs. I also had the summit wanna be flow masters on too.. Straight throughs sound better actually quieter cruising until you get on it then straight through are louder.
It is loud and is shizzy sounding at lower rpms, but at WOT my car sounded mean...now I have a glasspack and a full boar muffler (magnaflow, but cheaper and flows more, yet still stainless). No sound clips till its fired up.....I hope in about 2 weeks.
