Borla Catback Exhaust for the Subaru WRX and STI is a full stainless steel exhaust system that uses slip fittings for easy install and removal. The piping tapers to 2.5in right before connecting to the downpipe for great fitment using stock or aftermarket downpipes. This system does not have any resonators and will be fairly loud, but not overly noisy and annoying. It will however net you some serious gains through out the power band and improve throttle response. The construction of this exhaust is second to none and as with any Borla exhaust, they offer their million mile warranty. You can be sure you will not be replacing this system anytime soon. Ground Shipping Only.
Fits hatchback only
Fitment Note: Borla's 140312 system was designed to fit with the stock downpipe only.
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.
