If you run full circ your fine if you run another open I would say tune expecially if your full out. But I ran 50/50 a lot just makes your car run a little leaner I belive
technically yes, but without a tune for it, its ok. it sounds awesome, but on hard upshifts sometimes itl pop and bang, and i feel like thats not great for the catalytic converter. since my last downpipe (hayward and scott) cracked at the weld for the cat. which may of may not be related. but as far as the engine goes, the worst you will get is a little bit of carbon buildup from over fuelling for a brief moment. TLDR, its fine.
Just scooped a 06 fxt ej20x swapped. Pretty stout little guy love em.
sweet...i got a 2006 with an sti drivetrain and HKS blow off valve.✌
How did you get the suby rumble? is it just uel headers or is there more too it? like an aftermarket intake or something
Does the bov need a tune aswell?

Straight piped sounds obnoxious.
