So lets start this off on the plus side of things. The headers gave Great performance gains, feels alot faster but, i think my truck sounds like shit now. Idling and low RPM sounds really throatie but when i got up to about 3-4 grand, had it had been a tv show i would have turned it off, it sounded like a honda with a fartcan on it. but then back around 5-6grand sounded really mean again. If it wasnt for that one slight sound error i would absolutely love this buy!
For anyone wanting to buy some they are good, i think with a different muffler it would be different, but im running a flowmaster single chamber....and not my favorite with the headers. Ill see if i can post a few video's tomorrow when i get up.
