Grimmspeed 3" Catted Divorced Downpipe 08-14 WRX / 08-17 STI

You are looking at a top-of-the-line fully USA built Downpipe. All materials, engineering, R&D, fabrication, etc are straight out of the USA. The tubing is CNC Mandrel Bent 304 Stainless Steel using our custom made bend dies which give you the best fit and performance possible. Please take a second to check out these 304 Stainless Steel flanges...a serious work of art. All 3 sides of the flanges are CNC Machined to perfection. If that isn't over-the-top enough for you, check out the new 3-D Contour Flange.

Instead of the exhaust hitting a flat wall like on most divorced downpipes, Grimmspeed has spent a lot of engineering(and machining) hours creating a nice smooth transition through the wastegate port for the ultimate in boost control for you. The outlet of the downpipe has a standard 3” 2-Bolt flange that will mate up with most aftermarket cat-backs on the market. They have also included a wideband O2 bung for you if needed. Having a secondary o2 Bung saves you time and money because you will not have to pay a shop to install one for you. During design, Grimmspeed utilizes in-house 7-axis FARO™ Arm to obtain extremely accurate fitments. What this means is, they scan all of the mounting points on the car, bring those into CAD software, and then begin designing the pipe around scanned oem data in solidworks CAD software. Most downpipes(or exhaust pipes for that matter) on the market are designed using fixtures. Essentially the competitors will create a welding fixture by hand off of an oem part. This leads to a ton of chances for things to be off. Grimmspeed doesn't take those chances. Grimmspeed has spent the capital on R&D equipment where others have not.....for you. By using a downpipe that is catless, it allows you to fully maximize your exhaust flow which will increase the ability of your car to produce huge horsepower and torque gains. Turbo power, response, and efficiency is greatly improved. Once you have added the Grimmspeed downpipe to your vehicle, you must be tuned. Replacing your factory catalytic converter sometimes causes a ‘cat converter efficiency’ check engine light. You can either use tuning to delete this CEL or you can use a mechanical fix.
