I personally love my GMPP (made by Borla) and would buy it again. Sounds great!

But, it's only a 2.25 inch so not much help if you plan on going for high horsepower (300+).

Magnaflow without a dought. Have one myself 2.5 catback sounds amazing. Low tone at a low rpm and it comes a live at high rpm.

getting gmpp would be a downgrade for a 2.4 since we have 2.5 inch exhuast except for the one bend over the rear axle which is 2.25
