Description Applications
 
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. GrimmSpeed's solution: The HIFFLOW Crosspipe with 1/2"+ Thick Flanges, 14 Gauge Tubing, TRIPLE Layer Flex Joint.

GrimmSpeed's Subaru HiFlow Crosspipe is made of 304 SS(flanges, flex, tubing) and has a pipe-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". 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 Steel tubing, maximizing exhaust flow from cylinders 1 and 4 to the manifold collector for faster turbo response.

Customers have seen up to 15 HP INCREASE when combined with our Ported Subaru Exhaust Manifold. Boost transition is improved over stock and helps airflow in the mid to high rpm range which the pipe by itself should net around 5-8 HP INCREASE.
