GrimmSpeed Up Pipe (3-Bolt, Black Ceramic Coating), 2002-2014 WRX & 2004-2021 STi

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 for your [aftermarket] 3-bolt header on the market. Aftermarket headers are often inconsistent so we used our reverse engineering hardware/software to scan the leading 3-bolt headers to determine the range of best fitments for our aftermarket up pipe. This allows us to be very confident that your flanges will be leak free and the up pipe will fit perfectly, every time.
