2017 C63 Coupe, Renntech Sports Muffler Exhaust
RENNTECH SPROTS MUFFLER FOR NON PERFORMANCE EXHAUST?
Anyone have the Renntech sport mufflers for c63 without the performance exhaust? Would love some insight before I go for it. Renntech rep down here in South FL told me that it sounds better than factory DPE? Takes?
