More from GrimmSpeed:
“Up until now all of you 06-07 WRX and 04-08 FXT guys have been unable to swap in a higher flowing exhaust manifold crosspipe because Subaru decided to change up the design in those years. Well today is your day, we have created an 06-07 WRX/04-08 fXT specific HiFlow Crosspipe!!
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.
The GrimmSpeed HiFlow Crosspipe is made of 304 Stainless Steel (flanges, flex, tubing) and has a pipe-wall thickness of 14 Gauge, this is the most “heavy-duty” pipe you will find in the aftermarket. 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 Steel tubing, maximizing exhaust flow from cylinders 1 and 4 to the manifold collector for faster turbo response.”
