This is a brand new complete Tsudo N1 Extreme Cat-Back Exhaust System.
This catback features high-flow mandrel bent tubing with a straight-through muffler which generates a smooth, deep sound and maximizes performance.
Note: For 1998-2001 models, the hangar directly behind the rear subframe will not reach the hangar for this system. Either a new, longer hangar can be welded on at an exhaust shop, or the exhaust can be installed without it. All other hangars are re-used.
60mm piping maximizes horsepower and torque gain for 2.5L RS naturally aspirated engine
Don't settle for a 3" WRX/STI catback for your 2.5RS! Not a direct fitment bolt-on like our Tsudo system
Oversized 3" WRX/STI catbacks will require modification of the front flange, and will cause a decrease in low end power and exhaust velocity
Features 60mm / 2.36in piping diameter with a 115mm / 4.5in exhaust tip
Muffler and piping fully polished to a mirror-like finish
Produces a deep, aggressive exhaust note
Tuned piping diameter maximizes power gains
Improves horsepower, torque, throttle response, and fuel mileage
Manufactured from T304 / SUS304 stainless steel for durability and high corrosion resistance
CNC machine mandrel-bent stainless steel tubing for maximum exhaust flow
CNC cut flanges and fully TIG welded construction
Perforated core muffler design for smooth, unrestricted straight through performance
Significant weight reduction compared to OEM exhaust system
Utilizes the factory exhaust hangars
Includes all necessary hardware (bolts and gaskets) for installation
Bolt-on installation with typical hand tools
