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 Doug Thorley Headers Magnaflow Catback Exhaust
Finally got the headers installed on the GXP. I'm loving them so far! I attached a second video of the Exhaust at different angles to try and truly catch the tone.

2005 Grand Prix GTP top speed
I always wondered how fast my car could go. Even with a low fuel curve (to small of injectors) I was still able to hit 154 mph. My speedometer only goes to 140 mph. So i had to a program called speed view on my Android phone. From 79 mph to 154 mph took 1.6 miles. Love the rush!!!-)

Sound Off: '07 Grand Prix GXP vs. '02 Mustang GT
Cammed/Headers/Open Cutout GXP, Bolt-On/Headers/X-Pipe/Loudmouth 'Stang I thought for sure that I had my buddy when he pulled in the driveway, but those SLP Loudmouths live up to their name at WOT. I definitely lost on volume, but I think my car sounds nastier.

400hp Grand Prix idle
Not all high horsepower 3800s have to be loud. This 340whp setup runs a stock Exhaust, stock manifolds, an engine that hasn't been cracked open, gets 28mpg on the expressway and even has luxuries like navigation and bluetooth. Whether you want loud and ostentatious or quiet and subdued we can get your 3800 set up.

2008 Grand Prix GXP Exhaust
Hooker aerochamber muffler. without resonator and stock GXP tips. Sounds like flowmaster super 40's without the raspy noise.

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.
