The GrimmSpeed 7065 HiFlow Crosspipe is engineered to enhance exhaust flow and turbo response in your Subaru. Constructed from high-quality 304 stainless steel, this crosspipe features heavy-duty 1/2 inch thick flanges and 14 gauge tubing, ensuring durability and longevity under high-performance conditions.
The unique design of the triple layer flex joint, not located in the bend, enhances the durability of the flex section, making it less prone to failure. This crosspipe is specifically designed to maximize exhaust flow from cylinders 1 and 4 to the manifold collector, which contributes to quicker turbo spool times and improved boost transition compared to stock components.
Adding the optional ceramic heat coating helps retain heat, which accelerates exhaust gas flow, particularly benefiting mid to high RPM performance. This feature is crucial for those looking to push their Subaru's capabilities.
Upgrade your Subaru's exhaust system with the GrimmSpeed 7065 HiFlow Crosspipe for a noticeable improvement in performance and response.
