Description
When searching for a high performance exhaust system for your Subaru WRX and STi, why not go with one of the most highly recommended manufacturers in the business? Invidia’s full 76mm (3 inch) mandrel bent stainless steel piping optimizes flow and minimizes turbulence with a unique exhaust path that deletes all unnecessary bends, unleashing horsepower that would normally be restricted. So whether you choose the ‘Race’ or the ‘Street’ N1, you will be getting an exhaust system that was designed to provide your 2.5L with more power.
Where the two Invidia N1 styles differ is their midpipe. The ‘Street’ midpipe features a flex joint for easy installation as well as an inline resonator giving this system an aggressive yet deep and subtle touring style tone, suited better for daily driven street cars. The ravenous Invidia N1 ‘Race’ exhaust features the same 76mm (3 inch) mandrel bent stainless steel piping but does not have a resonator or flex section. The result is a much louder, race car exhaust tone that will scream at wide open throttle. All Invidia N1 exhaust systems for the WRX/STI include necessary hardware and gaskets for installation. N1 Exhaust systems vary depending on body style, please choose accordingly below.
Note: Are you using a stock j pipe or downpipe? If yes, the GrimmSpeed Subaru Stock DP to Aftermarket 3 in. Catback Adapter p/n 077046, is required.
