Mach Shorty Cat-Back Exhaust Kit

This Solo Performance G8 Mach Shorty CAT Back Exhaust Kit is specifically designed for the 2008-2009 Pontiac G8 GT and GXP models with either manual or automatic transmissions. The kit is constructed from polished stainless steel, both inside and out, ensuring durability and a premium appearance. It includes all the necessary components for a complete installation, such as exhaust tips, J-pipes, a muffler, and clamps. The "American Muscle" classification signifies a more aggressive and louder exhaust note compared to milder systems, making it ideal for enthusiasts seeking a distinct sound profile. While the exterior sound is rated a 7 out of 10, the advanced J-pipe design effectively minimizes interior cabin noise, keeping it around a 4.5 out of 10 and avoiding unwanted drone or rasp. This balance allows drivers to enjoy the aggressive exhaust note during spirited driving while maintaining a comfortable cabin environment for daily use. When the V8 transitions to 4-cylinder mode, the sound has a noticeable, sharper octave change. While driving uphill, the exhaust can be heard contributing to the "pull" but does not develop into a drone or hum. Feedback suggests the 4-cylinder mode might produce a "guttural" sound, which some users may find less than ideal, and it is recommended to "tune out" this mode if it's a concern. The larger 3.5" dual tips option is available but requires the GXP valence. Free UPS shipping is included for the continental United States and most of Canada.
