2008-2014 Subaru Impreza WRX STi
Notes: The crème de la crème of the catback exhausts for your GR/GH Subaru! The R400 boasts robust 3.15" tubing with quad 4" tips that look as great as they sound! The R400 has become the benchmark for catback exhausts systems for these cars. With fantastic fitment, finish and design, your neighbors will hate you but you will love your car so much more. Much rumble, such wow. If you have the stock downpipe, don't forget to add in this boi from our friends at GrimmSpeed!
