GrimmSpeed V2 GESI-Catted J-Pipe [2015-2021 Subaru WRX]

2015-2021 Subaru WRX V2 GESI-Catted J-Pipe by GrimmSpeed

Just because an existing GrimmSpeed Product is one of the best performing, highest quality, fan-favorite parts in the industry, doesn't mean there isn't room for improvement. The fully-redesigned GrimmSpeed Version 2 GESI-Catted J-Pipe for the 15-21 WRX is the perfect example. GrimmSpeed took everything that made the original J-Pipe so great and brought it to the next level!

The first thing you'll notice is that The GrimmSpeed Version 2 J-Pipe is now a 2-piece design. This not only helps to keep the U.S. welding/manufacturing, packaging, and shipping costs down to keep the end product within a reasonable price range, but it also allows for easier solo-installation of the pipe. No more having to use exhaust stands or taking your chances by trying to balance a 6' steel pipe in the air!

Another major design change is the cast steel collectors surrounding the cat. These not only look phenomenal stamped with the GrimmSpeed logo but also allow for optimized exhaust flow compared to other aftermarket offerings. They include the 3rd bung, giving you the option to run an additional sensor/gauge without having to drill and tap the unit. The cast collectors and 2-piece design of this pipe also allowed GrimmSpeed to further improve ground clearance over our original design. This results in an additional inch of clearance, especially crucial for lowered cars.

The inclusion of the GESI Catalytic Converter is one of the major changes for the V2 J-Pipe. While retaining the high-flow characteristics of our former high-flow cat, the GESI is a much more robust unit in its ability to clean particulate matter that is part of the combustion process, while retaining all the benefits which are expected from a GrimmSpeed Product. It also gives us the flexibility to insert it in a much more desirable and better operating location, mimicking OEM placement.
