I had some shorties on my old 5.3 and i just recently purchased an 07 NBS Silverado. Had it tuned by Nelson and have a CAI. Iloved the old headers I had but want to go with some long tube headers this time.
The shorts were nice cause they bolted right up to the stock system, my question is if i get some long tubes, do i still have cats, and do i need to run custum pipes? Any info would be greatly apreciated!!
