    • Product Description

      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 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 PnP Subaru Exhaust Manifold. The pipe by itself should net around 5-8 HP INCREASE.

      Add on our amazing Ceramic Heat Coating for a VERY SMALL fee to help keep the heat in and speed up those exhaust gasses even more.

    • Manufacturer Insight

      GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered products.

      The company's founder, Justin Grimm, has always had a passion for Subarus. Just like most enthusiasts, he was satisfied with his vehicle's performance stock, but could not resist the urge to see just how much more potential was left untapped. After a few years of perfecting his ideas and techniques on his own personal Subaru, Justin decided to turn his passion into a career. He immediately realized the niche market for Subaru aftermarket performance and founded GrimmSpeed, initially performing all of the work out of his own garage. As the demand for his own high quality products grew, he opened a new shop in St. Paul, MN. Enthusiasts quickly took to GrimmSpeed, and it became necessary to expand even further to a larger location. In January 2010 GrimmSpeed moved into a 6500 SQ FT shop in Minneapolis, MN. This move has given GrimmSpeed the opportunity to expand for years to come.

      Due to the extreme weather conditions of Minnesota, GrimmSpeed has unique opportunities to test their products to ensure quality performance. This allows the engineers to take advantage of a very wide range of conditions for product testing. This enables GrimmSpeed to continuously perform research and development on all products and make revisions accordingly.
