Mustang MAC Pro Chamber Mid Pipe
Quickly, and easily, bolt on an unforgettable sound, while also increasing horsepower, with this MAC 1999-2004 Mustang Pro Chamber mid pipe! Mac's patented Pro Chamber mid pipe helps produce more horsepower, and torque, by merging exhaust pulses into one area. By merging exhaust pulses, generated by your engine rotation, into a single chamber; this increases the temperature which increases the velocity and flow of your exhaust. This results in an increase in power and a broader torque band! MAC's testing has shown an average gain of 23 rear wheel horsepower throughout the RPM range.
Pro Chamber Signature Sound
Unlike the usual X, or H, crossover designs; MAC's Pro Chamber crossover produces a sound that is unlike anything else out there. Each tube, from your headers, flows into a boxed chamber, and then out of flow tubes that connect to your catback. You'll experience a mild hum at cruising speeds, and a menacing rumble during wide open throttle!
MAC has produced exhaust products for over 45 years, and the quality and experience shows in this Pro Chamber. Constructed with 2.5" mandrel-bent tubing, this mid pipe provides increased exhaust flow with no restrictions. The aluminized steel construction is durable, and built to last. MAC designed this Pro Chamber to fit their long tube headers on Mustangs equipped with both 5 speed, or Automatic, transmission.
This mid pipe has no catalytic converters, and is meant for off road, or track use only!
