Hell, you can get over 600 with just bolt ons.

would have been alot faster if they shed some of that weight the gto was stuck with. though you cant really argue with any LS series motor. i had 10's on my 2002 mustang gt. sounded a little more quiet, though i was pushing 650rwhp.. granted it was at 16psi with a kenne bell. nice car man.

sounds wicked fast i want one now

The 2005/2006 GTO's come with the LS2 Corvette engine. Pushing out 400 horse 400Lbs of torque. These things stock are monster engines, you put a magna super-charger in this baby you'll get between 510 to 560 horse, I've heard of other kits getting you 610 horse.

yo how much HP does that baby have it sounds like it has over 400

I got ahold of some slighly used Delta force mufflers on craigslist for like $100, and the installation was a deal at $90, here in Lake Forest, CA.

holy crap how much

I really have grown a liking to these GTO's. I think they are a great alternative to the cliche mustang, they are pretty bad ass and unique. Good Work.

shit

sick
