1/2"+ Thick Flanges,14Gauge Tubing, TRIPLE Layer Flex Joint. We are DURABILITY.

Subaru supplies its turbo owners with a tiny little crosspipe from the factory. 50% of your exhaust gasses are passing through this tiny pipe and, well, that's just a problem. Do not worry though, GrimmSpeed has a solution for you!

The GrimmSpeed Subaru HiFlow Crosspipe is made of 304 Stainless Steel (flanges, flex, tubing) and has apipe-wall thickness of 14 Gauge, this is the most "heavy-duty" pipe you will find in the aftermarket. Manyother pipes use cheap thin steel andare marketed as"super light weight", notus.The one of a kind Triple Layer Flex Joint is not located in the bend, which adds to the life expectancy of the flex section. This unit is built from 1.92" 304 Stainless Steeltubing, maximizing exhaust flow from cylinders 1 and 4 to the manifold collector for faster turbo response.
