Ultimate Racing 3" Catback Dual Muffler Exhaust | 2008+ Subaru STI | 2011+ WRX Hatchback (10047)

The cat back system is a beautiful device however it was not compatible with my 08 STI. The flange distal to the resonator was against the driveshaft when bolted to a Perrin down pipe. The turbo on my car was of standard size and in stock position. I would be cautious about ordering this product. My installer is a certified Subaru mechanic with years of experience with aftermarket part installations on STI's. He builds race cars on the side. G Walker MD
