Had a pro sport back box fitted today, sounds good not loud so just right .
When I came home i got out to listen to the idle and noticed the exhaust sounds as if its popping rather than being burbling smoothly. Just wondering if this is the norm or if I better get the car diagnostic checked to see if the fitment has thrown anything out of sync etc.
The back box is as close to oem i could get with 2.5 slash pipes and made to be as quiet as possible so it gives a nice growl, its the idle noise I am not sure about as I wanted that as smooth as possible.
Before I go back to the fitters and ask them (who I must say are excellent) I wanted to get some pointers/advice please
