The Version 2 GESI J-Pipe does retain the best qualities of the original tough 3" 304 stainless steel construction, thick 1/2" flanges, and the type of fit and finish that drivers come to expect from GrimmSpeed. The first noticeable change 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 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 a 3rd bung, giving 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 allows for the flexibility to insert it in a much more desirable and better operating location, mimicking OEM placement.
