07 VortecMax Sierra

supergas · 05-27-2008, 05:26 PM

I am looking for a "Factory" cat-back dual outlet exhaust system for my 07 Sierra with the 6.0 VMax package.

I thought I saw one in GM Performance Parts but cannot find it. I am looking to add the exhaust, intake & programmer to see if I can get over 400 HP out of this thing... It runs pretty good now but could do better & may get a 1 or 2 MPG better.... I do a lot of highway driving @ 75 or above...

Anyone know who makes the best exhaust system for the 6.0 ???

Thanks,

Supergas

If you want to go with GM, just go to the parts dept where you bought it.

If I was going to do it, I'd go with Flowmaster. When I looked at this site, all I got for the 6.0 is a Gibson system for $450:
