Modded Grand Prix GXP 5.3L LS4
Did a pass around 50ish to hear the Magnaflow Cat-back Exhaust. Then did a 0-120ish. Started out half throttle and slowly worked it to about 3/4. Had to slow down because of a sharp turn. Thanks for watching.
2006 Grand Prix GXP MagnaFlow's Big Burnout 0-55ish held to the wood to 137
Had new tires setting at Discount Tire... Not every day you get to rip it like this plus you get to share it with other gear jammers on YouTube! Not sure what the high pitched whistle it after 110.... Any ideas? Never heard it in the car before this video... Got it up to 154 just before rolling the cam on this video with no whistling. Enjoy some shredding of the 255/45/18 BFG KDW's!!
