GrimmSpeed HiFlow Exhaust Manifold Crosspipe (04-10 STi/02-05 & 08-10 WRX)
001001 - 001001
The new GrimmSpeed 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", 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. Customers have seen up to 15
HP INCREASE when combined with our Ported Subaru Exhaust Manifold. The pipe
by itself should net around 5-8 HP INCREASE. Check out our amazing Ceramic
Heat Coating option to help keep the heat in and speed up those exhaust
gasses even more.
