Bullet Performance’s Ford Mustang High Pitch-No Drone X-Series exhaust system offers an extremely high flowing design in comparison to the OEM unit, and optimizing flow throughout. We only utilize Mandrel bent 3 inch. diameter high quality stainless steel, keeping all bends truly unrestricted and wrinkle free. One of our secrets to our higher than expected performance numbers can be attributed to our large radius bends. These large bends actually facilitate higher flow than the tight radius bends that are an industry standard, and for this reason they produce more horsepower and a sweeter sound! Our Ford Mustang customers will tell you they prefer the crisp and high pitched exhaust note from this system over any other, and there is a reason for this exhaust symphony; smooth laminar flow translates to a precise and high pitched sound! With a Bullet Performance Catback on your Ford Mustang you will enjoy greatly improved engine response as well as driveability, however the most impressive improvement is the sound.
