At Least until i do headers. Any reason not to? Other than a little louder?
Your factory exhaust pipes, with the resonator in place and the flapper and muffler deleted, will sound GLORIOUS with long tubes.

... and, this may be hard to accept- but there ARE no crew cabs in the low 13's. Anywhere. Its a myth. Thats why googling it didnt turn up anything.

I have a friend with a '15 crew cab 5.3 4x4 on 22s with a procharger running 13.5. He just had a TSP custom blower cam and DOD delete kit put in but is yet to run. My '15 double cab 4x4 5.3 with Intake, magnaflow exhaust and Diablew tune only runs a 14.7. How are you guys running 14.5 tune only?

Before/After

Looks great! Where is it rubbing? I am thinking about going this exact route as having the opportunity to take a $30k truck off road i'm still making payments on just doesn't sound appealing! Please PM as I do not want to route this thread
