ETS Quiet Cat Back Exhaust System Blue Tip Resonated - WRX / STI 2015 - 2021

The Extreme Turbo Systems Cat-Back Exhaust System is made in house right at ETS, and features true 3” piping all the way through the mid-pipe that connects to the rear section that splits into a pair of 3” pipes that ends in quad 3.5” tips. This results in better throttle response, increases in both horsepower and torque, and best of all an improved aggressive sound. 

The design of this exhaust system is held together by v-band clamps with the exception of the factory style 2 bolt flange that make sure for a leak-free operation. This exhaust system has factory placement exhaust hangers, and comes ready to install with 3 V-band clamps, a vibrant 2 bolt gasket, and hardware.
