I know what kind of motor is it, lol. all GTP have them.

There is no exhaust restriction from the catback, trust me, dont go wasting your money on doing 3in exhaust, there is no point to it.

The exhuast mods you need is headers, the front mainfold is un godly restrictive and with the 3.4 on there its prolly KR* ing like a mofo. It's going to chip a piston real quick if your not careful and take it off before its to late.

Dont put flowmasters on there, your ears are going to bleed from the god awful drone. Buy some magnaflows or borla, flowmasters are chambered mufflers and those are the ones you DONT want, they suck.

FYI: headers come with a downpipe, you dont have to buy both.
