Starting at the final flange of the downpipe, 42's 3" cat-back bolts up without modification using locking hardware and a double layer graphite gasket. A slight 3" mandrel bend tucks a straight-through resonator into the heatshields away from road debris. A stubby hanger and a series of mandrel bends routes 3" tubing under the rear suspension to a CNC machined adjustable flange connection. Exiting the flanges, tight radius 3" mandrel bends allow exhaust gases to enter the rear muffler. Inside the rear muffler exhaust gases are divided into an opposing pair of 2.5" outlets. Tight radius bends and precision hangers position two stainless steel tips perfectly in the rear bumper.
At idle, the TT emits a suggestive rumble. At low rpms and cruising speeds the sound is sporty and refined. The exhaust opens up at full throttle and high rpms with a powerful tone and not a hint of rasp. Inside the car, the shape of the hatch and rear end design naturally amplify exhaust sound. With the rear seats installed the volume is minimal and the system does not drone. During testing 42 experimented with various resonator and muffler combinations before finding the perfect balance of power and sound.
Installation is simple, adjustable, and reliable. A permanent flange allows the system to bolt to 42's 3" downpipe. Precise design and fabrication routes piping clear of heatshields. Adjustable flanges allow further adjustment if necessary, sealed by double layer graphite gaskets and locking hardware. A pair of collars on each rear hanger lock the muffler in place. This means your tips will never slide out of place.
