2007 Pontiac Grand Prix GXP 149 MPH
As you can see, I went 149 MPH in my Grand Prix, It could have gone even faster but the guy who retuned my car somehow screwed up the speed governor so it couldn't go any faster than 149 MPH.
At the time the mods to the car were a Magnaflow Cat Back Exhaust, K&N Air Intake Kit, and a Jet Mass Airflow Sensor.
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.

Grand Prix GXP Catless Downpipe & Cutout Driveby
2008 Pontiac Grand Prix GXP with catless Hogan downpipe & open cutout located just before the Y-split for the rear mufflers.
Pavement was more moist than I thought which is why I let off when & then bounced off the limiter in 1st gear when I first took off. The Exhaust note is too raspy...I'll be getting some sort of bullet muffler for it soon. Maybe a Borla XR1.
