Custom exhaust build
Has anyone built a custom down pipe for the 12' 3.5 F150? I am a specialty pipe welder and was planning on building my own this weekend, at least starting it, I planned on basically straight piping from turbos back, I was thinking 3" off the turbos to 4" straight back after the Y. Thoughts and feedback please and thanks. Truck has afe stage two intake, sct x4 with two five star tunes(93performance, 91performance/toe) I planned on getting a dyno custom tune when it's done.
