I did 4" out of the fender, it was a straight shot, well mostly, off the turbine. I will be going to 5" when the new motor/turbo go in the car. Its a stock motor with a 76mm on it now. I would just put 80lb injectors from the start, lots of room to grow with those.

Anyone else get any backfire issues at all on decell? I just got my car out so my tuner and I are still working on the tune and all but was just curious.

Do any of you guys running the open DP have any backfire issues on decel or when letting off the gas? Mine seems to occasionally give me a slight backfire on the decel...

On force induction your always run you a/f little rich. So on decel after a pull your still gonna have un burnt fuel in the exhaust which ignites from the exhaust temp causing a backfire. On sorter length exhaust its worse
