Product Description

Designed and developed to produce maximum usable power, all Mach 1 exhaust systems have been both dyno and track tested. Dyno results show great improvements in torque and peak horsepower while our track test proved it with faster lap times. Complete with our Moflow headpipe, Pro-Tec Mach 1 exhaust systems are available in full competition or U.S.F.S. approved versions. All Mach 1 exhaust systems are thermal ceramic coated for temperature control and good looks.

Mach 1 exhaust systems by Pro-Tec are available with the optional A.N.S. The Pro-Tec Adjustable Noise Suppressor is quickly adjusted to reduce decibels in environmentally sensitive areas. No caps to remove. No parts to add. Adjustments are simply made by spinning the inner plate to the desired position and resetting the lock bolts.
