OK, that just sounds SWEET!!

LOL! I LOVE the raspy deep growl of my GXP. For a stock setup it's awesome. Nothing makes it sound better than kicking down into 2nd with the TPS controlled Nitrous armed. It cause more wide eyed dropped jaws than you could imagine :cool:

is that a V6?

GXP Venom 10-21-2008 11:57 PM

No, the GXP trim model comes with a NorthStar 4.6 V8.

I put a pair of Flowmaster 50 (Delta Flow) mufflers on the GXP at 30k miles. Awesome sound. With the OEM GMPD mufflers, the sound was good at half to full throttle. However, the entertainment value of draining the tank to enjoy the bellow produced a considerable negative cash flow!

The Flowmasters entertain me simply rowing the gears up to 2000 RPM, but can induce whiplashed toll booth attendents upon launch. They sound muscular at idle and low RPM, and explode to roar with mashing the right foot.

Do you have a sound byte of the Delta 50's. I'd like to do them to my car. The part numbers would be helpful too.

Sounds good. I installed 40 series flowmaster's on mine. Sounds similar except it seems like the 40's idle at a lower deeper rumble.

Yea, sounds sweet....... sounds alot like a stock 2000 corvette. A guy at work has one and side by side with my GXP they both sound alot the same.......
