Chrome. A classic 2 into 2 system with cutting edge features. 2 1/2" diameter; full length heat shields wrap 222° around the exhaust pipe for a virtually no-blue experience and are finished with chrome billet tips. The power port connects both mufflers for best midrange and bottom end torque and does away with the need for a balance pipe between the two exhaust headers. Since head pipes are therefore not connected you get the clean and uncluttered look. The baffles are removable and give a great deep sound. Note: A quiet baffle is optionally available as 915522; a replacement baffle as 915525.
