Show original supplier description
The Extreme Turbo Systems Cat-Back Exhaust System is engineered to deliver uncompromising performance for the Mitsubishi EVO 8/9. This system is designed for maximum power gains, utilizing either 3.0" or 3.5" mandrel-bent stainless steel piping coupled with a high-performance Vibrant Performance muffler for an optimized combination of performance and aesthetics. The exhaust system starts at the cat, tucking closely into the driveshaft tunnel to preserve near factory ground clearance. The piping expands to a 4.0" diameter before connecting to the 4.0" muffler inlet, and exits through a 4.0" tip angled at 15 degrees, providing a race-inspired appearance and high-performance capacity. The system is available in either USDM or JDM fitment options and with either 3.0" or 3.5" diameter piping. Users have reported great sound quality, with a deep tone and no rasp, described as not too loud but not too quiet. The build quality and fitment, even with a JDM rear bumper, have been praised, with the 3.5" version clearing the driveshaft tunnel and CV joint with ample room. Installation is further simplified by the inclusion of necessary hardware and slip-fit clamps.
