Description

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. 

Please Note: You will need to slightly adjust the divider tab to fit a VF40 turbo. It’s a very simple process but please contact our customer service representatives if you have any questions.

This downpipe completely changed the car. I come on boost about 1k earlier and stay on it until shift. The sound is also incredible. Its paired up with a nameless performance catback, and it honestly is one of the best sounding WRX's I have heard, and I have been working on Subarus for a long time. The only downfall is you need two of them, one for the car, one to hang up in your mancave, it's that beautiful. Also re-routing the o2 sensor harness only takes a few minutes, not a deal breaker at all.

This downpipe is a work of art! I have a lot of grimmspeed products and this like all the others is top notch. I installed this and partnered it to the perrin non-resonated cat-back exhaust. Along with some other mods a got a protune done and the car put down 295whp and 321wtq @18 psi on 91octane. Awesome product!

Easy Install, Great Quality.

Install was easy and the quality of the product is great. I've had the Invidia and and Cobb before, the GrimmSpeed is definitely on par with the Cobb, but with nicer welds :). Divorced is definitely the way to go for stock turbo.

    Answer

    Will this downpipe work with my stock midpipe on my 2018 STI??


    • A: No it will not, you will need a 3in downpipe to stock catback adapter. Like so: https://www.rallysportdirect.com/part/exhaust-gaskets-and-hardware/grm-077044-grimmspeed-3in-downpipe-to-stock-cat-back-adapter

  • Q: Map compatibility  STi-lvr 1 year ago

    Answer

    I have a cobb accessport (currently running stage 1 on a stock STi). I already ordered my invidia q300 catback and am wanting to go with this downpipe. My questions is, will this downpipe work fine with the cobb OTS stage 2 map? I have heard mixed reviews, from the divorced wg tube isn't as good as the cobb bellmouth, and that the cat on the gs downpipe wont work right with cobbs OTS map because it may change back pressure. Will I have any issues running the stage 2 map with this downpipe?


    • A: We cannot confirm it to not have any issues although the ECU should be able to compensate enough for the differences.

  • Q: SMOG with aftermarket downpipe  Nelliebob06 1 year ago

    Answer

    Hi I have a 2009 Forester XT with the ej255 engine I was wondering if this downpipe would allow me to pass California emissions? And if this one will not Pass California emissions, is there another 3 inch downpipe for my car which will? Thank you very much!!


    • A: We do not comment on the legality of state emission testing. We state all our products are for off road use only.
