The new GrimmSpeed Subaru 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.

Grimmspeed designed this Up Pipe using 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.

For those looking to take the finest downpipe one step further and wring out every last ounce of performance, Grimmspeed offers the 'Limited' line of downpipes. Limited downpipes use flanges made of the very same 1/2" 304L Stainless material, but are fully machined with recesses for each tube as well as a beautiful 3D contour to smoothly transition the irregular shape of your internal wastegate outlet into our divorced tube for tighter boost control. In addition to the machined flanges, limited downpipe tubing material has a brushed finish, for a more uniform, refined appearance.

An External Wastegate (EWG) allows exhaust gases to be diverted prior to entering the turbo. This facilitates lower backpressure at the turbine, allowing for increased boost control, faster spool-up and greater top-end power. The GrimmSpeed EWG Up Pipe has a larger internal diameter than your stock unit, allowing a higher volume of exhaust gas to reach your turbo more efficiently. This helps maintain boost levels further into your RPM range. Depending on your specific setup, these improvements can net a 10-40 HP increase. A downpipe is one of the first modifications that should be done on your car, as the OEM downpipe contains two very restrictive catalytic converters, killing the power potential of your car. Within our complete lineup of downpipes, you have the option to add a high-flow, 300 cell catalytic converter, fully machined and contoured flanges with beautiful brushed tubes and black ceramic coating. Whether you're racing time attack or to work and back, we've got the perfect downpipe for you.

An External Wastegate (EWG) allows exhaust gases to be diverted prior to entering the turbo; creating quicker turbo spool. The GrimmSpeed EWG has a larger diameter than a stock internal wastegate; this allows the exhaust gas to be released faster, which improves boost control, maintains maximum boost longer in the rpm range. All of these together will give you a 10-40 HP INCREASE. Moving the wastegate out of the turbo relieves the turbo from the massive amounts of turbulence that the stock internal wastegate creates.
