Description

This 2-bolt up-pipe is designed for EJ25 engines with an OEM-style 2-bolt header configuration. It features ½" CNC-milled stainless-steel flanges, heavy-duty 14-gauge 304 stainless steel tubing, and a 321 stainless steel "Tuned-Bellow" flex joint. The pipe-to-flange connection is ported flush for smooth flow. Each unit includes GrimmSpeed Fire Ring multi-layer steel gaskets and corrosion-resistant zinc-coated hardware. Available in raw stainless steel or black ceramic thermal coating (for reduced engine bay temperatures and heat soak). SEMA Certified (SC-GRM01-0145) and CARB Certified (EO #D-896).
