hi

i just get a custom midpipe installed today. but the exhaust is loud as hell rite now, i cant even hear music inside the car. just want to know is it possible the shop installed the resonator in the wrong way ( inlet and outlet in the opposite side) so the resonator is not functionable?

anyone can help???

also, any good aftermarket resonator u guys can recommand me? i want some really quiet one.

thx
