Product Description

A TOP OF THE LINE UP PIPE MADE TO BE ABUSED.

Adding an aftermarket Up Pipe is one of the first things you should do to your Subaru. Arguably one of the best $/HP ratios. Our goal was to make a premium heavy duty Up Pipe for you.

Design

We designed this Up Pipe using our in-house FARO Arm along with the latest and greatest Solidworks CAD software. This assures that we can offer you the most precise and best fitting Up Pipe on the market. In short, OEM exhaust manifold pieces are inconsisent so we used our reverse engineering hardware/software to scan countless OEM pieces to determine the range of best fitments for our aftermarket pipe. This allows us to be very confident that your flanges will be leak free and the Up Pipe will fit nicely.

Materials
Our Up Pipe has been made with beefy local raw materials. The flex joint is 321 Stainless Steel w/ an Interlocking Liner and tubing is a heavy duty 14 Gauge 304 Stainless Steel(competitors use thinner 16 GA) that has been CNC Mandrel Bent and finished up with a nice brushed finish. Our flanges are made out of 1/2" 304 Stainless Steel and are fully machined on all sides(competitors typically just laser cut flanges for cost reductions). We also put a nice bevel on the edge of the flange so you don't cut yourself. You're welcome. The insides of our flanges are "cut-back" to allow the pipe to rest inside the flange which gives you a nice flush mating surface thus allowing optimal flow through the pipe. Heck, we started as a Porting company afterall....we take pride in exhaust flow quality through our pipes.  All fabrication is completed by our Welder/Fabricator who is certified in Aerospace Welding...yeah, he knows his stuff. A bit of overkill using an Aerospace Welder you say? Well the Up Pipe is put through some very harsh environments so we wanted the best for the job.

GrimmSpeed Up Pipe Install (09:58)
Adding an aftermarket Up Pipe is one of the first things you should do to your Subaru. Arguably one of the best $/HP ratios. Our goal was to make a premium heavy duty Up Pipe for our customers! The entire Up-Pipe 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 inlet size is 1.92" and the pipe tapers down to 1.72" which acts as a funnel as it moves into the turbo allowing for the smoothest transition and best air-flow quality. 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. Our outlet size is a perfect match to the most common stock location turbos allowing for a smooth transition into the turbo.Since we are a porting company we make sure to have the smoothest transitions between pipes to allow for maximum flow and quickest spoolup(we call this "quality airflow").
