Hey guys...I own a 2006 GMC Sierra Custum and I reciently called my buddy (Dustin) from JBA here in san Diego, Ca. He hooked me up with a killer JBA exhaust system and refered me to one of his friends at Permier Truck Accessories. The guys name is Dave here is his web site and phone number..
[URL="http://www.premiertruckaccessories.com"] (623) 344-5054. He is out of Phoneix, Az and he will get you the parts you need ASAP. I picked up the Voluant Cold Air Intake System and it was at me door in 2 days. I put it in and BAMMMM. Instant power increase and thanks to Dustin, I have Killer intake and Killer Exhaust.

I highly recommend you check these guys out, Give them a chance at what parts you need and I will bet you hands down that they can hook you up with out any hesitation...NO BU$$ $hit...
