GrimmSpeed Downpipe 3" Catted LIMITED w/ Black Ceramic Coating - Subaru WRX 2008-2014 / STi 2008-2020 (+Multiple Fitments)
The Grimmspeed Limited Divorced and Catted Downpipe is 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 their 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. 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 their design, they utilize their 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 their CAD software, and then begin designing the pipe around their scanned OEM data in their Solidworks CAD software. Most downpipes(or exhaust pipes for that matter) on the market are designed using fixtures. Essentially their competitors will create a welding fixture by handoff of an OEM part. This leads to a ton of chances for things to be off. They don't take those chances. They have spent the capital on R&D equipment where others have not.....for you.
For those looking to take the finest downpipe one step further and wring out every last ounce of performance, GrimmSpeed offers their '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 GrimmSpeed's 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.
Because this product replaces/removes an OEM emissions control device we must state that this product is for offroad use only.
New hardware and gaskets will be included to make this downpipe ready for the installation. Also, note that this particular downpipe will come with the black ceramic coated finish to provide extra protection against rust and corrosion, and to lower underhood temperatures.
Please Note: You will need to slightly adjust the divider tab to fit a VF40/VF46 turbo.
