Mufflers, maybe. There is a lot of conflicting information about this and our cars in the various forums and on some of the exhaust manufacturer's websites. It would be nice to see before and after dyno runs.
Resonator: I wouldn't expect any
significant change in back pressure from this mod and I would think that any change, if there is one, could be compensated for by the ecu.
My interest is to increase the sound level of the exhaust without adding any interior drone (which the coupes are prone to with their large rear cargo area).
