I wanna know who quoted you that 475hp #

Why the X pipe?
What warranty do you have left on a 2010 anyway?


475bhp, probably at the flywheel, but I have a less restrictive system than you're talking about (no tune though because I want my warranty and the car runs great without one [i don't understand why people insist LTs need a tune]) and make 422-428 rear wheel hp depending on the humidity. I'm just saying you're not gonna see that # with those mods.
