Injen Cat Back Exhaust with Quad Titanium Tips For Subaru WRX STI (2015-2021)

Injen 15-21 Subaru STI Cat Back Exhaust w/ Quad Titanium Tips

We design every performance product with ease of installation in mind. On the SES1207TT we've included V-Band clamps and flanges for the simplest, quickest installation possible. No need for any cutting, drilling, or modification of the vehicle to complete installation. The system uses all factory mounting points for simple and convenient placement and compatibility. To increase performance, we opted for a stepped piping design that keeps the flow rate consistent throughout the length of the exhaust. Keeping the flow rate consistent not only adds performance but also helps keep the tone of the exhaust where we designed it to be throughout the rev range.
