Invidia N1 Single Exit Cat Back Exhaust 2015-2021 WRX / 2015-2021 STI
This is the Invidia N1 Cat-Back Exhaust System. The N1 is one of Invidia's most popular cat-back options offered in their catalog due to the quality stainless steel construction that combines smooth bends with an increase in piping diameter. This allows for an unobstructed flow path for the exhaust gases to exit which will increase both the horsepower and the torque while improving the overall throttle response. Additionally, users will be rewarded with the race-inspired sound this exhaust system will create which will make the overall driving experience much more enjoyable.
