GrimmSpeed 15-21 Subaru WRX J Pipe GESI Catted V2

Exhaust systems are a great way to enhance the looks, sounds, and performance of your vehicle.

Downpipes are the first part of the exhaust that connects your turbocharger to the rest of your exhaust. Many OEM downpipes are known to be restrictive with their piping diameter. If you are looking for a simple way to increase the horsepower on your turbocharged vehicle, we recommend replacing the OEM downpipe with an aftermarket downpipe. After installing an aftermarket downpipe, you will likely need a tune to adjust for the change in air fuel ratio. After getting a tune, your vehicle should perform better and have a better throttle response.

GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered aftermarket products. On a more personal level, we are a group car enthusiasts who are working our passions in the lovely city of Minneapolis, Minnesota. Our bread and butter started out anything Subaru. However, after growing our team and engineering expertise, we started developing products for Mitsubishi, Ford, MazdaSpeed, and Hyundai markets. We are a true garage start-up (single stall townhouse garage in Maplewood, Minnesota) and we've been lucky enough over the years to be able to turn it into exactly the business we had dreamed....actually, much more. We have a wide breadth of product offerings including; intercoolers, exhausts, intakes, gaskets, engine pulleys, phenolic spacers, boost controllers, and many more.
