An often overlooked part of the exhaust system on turbocharged Subarus, the OEM exhaust manifold crosspipe is a tiny restrictive pipe that 50 percent of the total exhaust gasses must flow through before reaching the turbocharger. GrimmSpeed took the time to address the issue and came up with this excellent High Flow Crosspipe that is built with their legendary durability. This bolt on part frees the exhaust path to the turbocharger, offering a solid 5-8hp gain in most vehicles and improves airflow in the mid to high range of the powerband. In addition to providing superior performance, the High Flow Crosspipe uses the best materials and construction for trouble free use. Some of the innovative features include; 321 stainless steel interlocking liner flex joint, 14 gauge 304 stainless steel piping, (33 percent thicker than most competitors tubing!) flush flange to piping junctions, massive 1/2 inch thick 304 stainless steel flanges and precise GrimmSpeed design using the Faro 7 axis arm and Precision CNC machining.

The quality, power and price of the GrimmSpeed High Flow Crosspipe make it the perfect upgrade for any build!
