if u messed with the intake and immediatly after got problems why the hell did u immediatly start assuming the u bend or car? start by finding out what u screwed up and leave the exhaust alone...for now
my thoughts EXACTLY. if you did indeed start having this problem right after you put on your intake, it is most likely that restrictive ass 3 inch piping your using.
why in the world would you make an intake with piping smaller then stock??
