GrimmSpeed J-Pipe GESI Catted V2
Subaru WRX 2015-2021 Manual Transmission Only
Features & Product Details
RallySport Direct proudly carries a great selection of quality performance upgrades by our friends over at GrimmSpeed.
This is the GrimmSpeed 3-Inch GESI V2 Catted J-Pipe. GrimmSpeed took one of their best-performing and highest quality design and still managed to make even more improvements. This is a fully redesigned version for the 15-21 WRX models and created a 2-piece design. This will help to keep the US welding and manufacturing, as well as the packaging and shipping costs down to provide the performance consumer with a J-pipe in a reasonable price range/. Additionally, it will help with the installation for those of you installing this unit alone, and you don't have to use makeshift exhaust stands or go through the hassle of balancing this J-pipe on your own.
Another great design feature is the cast steel collectors that are surrounding the car. These are stamped with the GrimmSpeed logo and also allow for optimized exhaust flow when compared to other aftermarket offerings. This design will also include a 3rd O2 bung to allow enthusiasts to install a wideband O2 gauge without any further tapping or welding. The cast collectors and 2-piece design allowed GrimmSpeed to further improve the ground clearance over the original V1 design which is very beneficial for those of you with lowered vehicles.
Implemented in the design is a GESI Catalytic Converter which is one of the major changes in the V2 J-pipe. This cat still maintains the former high-flowing characteristics in a much more stronger and robust construction that has the ability to clean the particulates without sacrificing flow, and the location mimicks the OEM location as well.
