Product detailed description

DINAN Sport exhaust silencer for BMW M3 & M4

DINAN Sport flap exhaust silencer. This full-thru muffler is all-stainless T304 construction and designed to fit piece by piece in place of the stock rear muffler. The connection to the stock exhaust is in the area in front of the rear axle and is connected using clips that are part of the exhaust. On the other side, the ends fit exactly into the hole in the rear bumper. Performance testing on the engine brake showed a 4hp increase, however more important with this part is the complete change in sound. The serial M3 and M4 don't sound like much to show that it's an interesting performance car. So the DINAN engineers decided that this car deserved a slightly pepperier exhaust sound and developed their exhaust system accordingly. The muffler is designed to provide a more aggressive sound at full throttle while at the same time minimizing unpleasant rumble and volume during normal quiet driving. The exhaust gases flow into the larger black tailpipes.
