Adding a well-designed, well-built aftermarket up pipe is one of the first things you should do to your Subaru. GrimmSpeed's ultimate goal was to make the best up pipe the aftermarket has to offer.

This Up Pipe has been made with beefy local raw materials. The flex joint is 321 Stainless Steel w/ an Interlocking Liner and the tubing is a heavy duty 14 Gauge 304 Stainless Steel (competitors use thinner 16 GA) that has been precisely CNC Mandrel Bent; the flanges are made out of 1/2" 304 Stainless Steel and are put through a tumbling process to smooth out the edges. The pipe is hand-welded on the inside of the flange, in addition to the outside, allowing for added strength to the finished product and a nice mating surface with optimal flow through the pipe. All fabrication is completed by GrimmSpeed's team of Certified Welders/Fabricators.
