1/2"+ Thick Flanges, 14 Gauge 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 new GrimmSpeed Subaru HiFlow Crosspipe is made of 304 SS(flanges, flex, tubing) and has apipe-wall thickness of 14 Gauge, this is the most "heavy-duty" pipe you will find. Many other pipes use cheap thin steel and are marketed as "super light weight", not us. 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.
Customers have seen up to15 HP INCREASEwhen combined with our Ported Subaru Exhaust Manifold. The pipe by itself should net around 5-8 HP INCREASE.
