gibson exhaust
 

just picked up a 08 sierra crew 1500. thinking about getting a gibson dual extreme system, just wondering if anyone else is running one and how it sounds

I have one on my 4.3 s10 and it sounds great. Check youtube for sierra gibson exhaust to hear examples =) Good day.

I put a set of Kooks headers on my 11 5.3 and am running a single in and dual out Magnaflow muffler. The response and sound is great. The cost for the exhaust was easy to handle, the Kooks were a little pricey, but I found them at a source that gave me as good a price as you could find on the web.
