Product Details

Adding an aftermarket Up Pipe is one of the first things you should do to your Subaru. Arguably one of the best $/HP ratios.

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