R4509 straight flow muffler, is designed for 0.8L~1.3L vehicles. This muffler helps reduce loud noise of 3-cylinder engine and produces aggressive sound, turning it into sporty and powerful machine.

For NA engine vehicles below 1.3L, we encourage to match this muffler with B.Cobra resonator to gain the best throttle responses.
