Injen Technologies has released their new catback and exhuast for the G35 Coupe, which looks pretty tight to me. Just not sure about the quality though, then again it is Injen. I haven't really heard anything about a Cat & Exhaust system from Greddy, but I'm pretty sure they're in developement. Which would you guys prefer? Greddy or Injen?

Upgrades never cease.

 

I had a Greddy on my last car. At idle there was no change in tone but when you hit the throttle it was very deep, similar to the G. At speed there was no drone.

I have the greddy on my sedan. It replaced that huge, heavy and heinous pre-muffler. It's only a single setup on the sedan, but the butt dyno says good things and it sounds great. Kinda throaty, and deep but not overtly loud or annoying in any way.
