GXP Exhaust with X-Pipe Installed

Finally got my car up on a lift tonight to install my new exhaust setup. We deleted the mid-muffler and resonators and installed an X-pipe to two GXP axlebacks. The sound is definitely not terrible. It's a little high-pitched, but that's what you get when you have a V6, no low V8 rumble. It sounds fantastic on idle, revs good under full-throttle, absolutely ZERO drone and 1500-2500RPMs (55-75MPH or so).

I'll try and get a fly-by video up soon. I personally think it sounds a lot better driving than it does revving it to 4k RPMs while parked.

Sounds good. The factory exhaust is way too quiet on the V6 and GT. I had GXP axlebacks on my GT before the powerflows and they sounded nice as well.

If anyone is interested in comparing Stock to your setup here is the link to the 0-95 run I made a while back before my intake.

Stock RSAs. I think I had about 19K on the tires then and I just had a K&N drop in at the time with the LPM. I have 24K now and with my intake I can now get rotations of spin but they are getting close to the wear bars so I am sure its just the difference in tires. I couldn't spin them the first summer I drove on them.
