That's certainly a way to get your exhaust louder, but it's a different path than a typical axle back/cat-back system.

I personally would recommend a cat-back change. Have you seen how ugly, big, and heavy the factory Cat-back is on these cars? I dropped mine off in one piece and replaced it with a Borla 60606 X Pipe and Corsa Xtreme axle-back and the sound is to die for. MUCH louder on start up and wide open throttle, ear splitting in the tunnels/next to concrete structures, but calms down and cruises nice and quiet. But as soon as you drop a gear, it screams.

I started my C7 Z06 and ZL1 back to back when both were stock, the ZL1 is loud and is a bit sharper on initial start up, but the C7 Z06 is just a bit louder on startup and stays louder once idling. By the way, the fuse pull is really a dumb idea on these 5 mode NPP systems. You might as well put it in track mode and at least be able to show your buddy how you can change the exhaust 5 different ways.

I went to Youtube and Phastek. It looks good. Also, they lifted the car at the same places the Chevy dealer lifted mine.

Did you put your own on?
