BMS-001Quiet Pipes, our signature product, are mandrel bent, baffled side pipes with no packing to be blown out. The sound is classic muscle car, no bark, not raucous, just smooth and powerful. At 70 MPH wind noise in the roadster is higher than engine noise! The quality of these side pipes has to be seen! Tight radius turn outs, smooth transition collector, and outstanding weld quality, combined with the removal of the “kink” in the passenger side pipe attest to the quality construction. Sound and tonal quality far exceed any other side pipes available. Quiet Pipes are Carbon steel, All new parts. Customer must coat or paint.
