mplavery Posted April 20, 2019 Share Posted April 20, 2019 Not that no on likes a popping exhaust but I have had my BPU set up for about 10 years and never really had the exhaust popping Taken the car out a few times this year inc today and though it’s not all the time it has popped once or twice on over run on every run so far Though I like it I can’t help thinking there maybe an issue Any one else have popping on BPU set up ?
