Description

You are looking at a top-of-the-line fully USA built Grimmspeed 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 which are 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 give you a provision if you want to use a wideband O2 gauge. 

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.

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.

Welds NSFW
NotoriousBIB 2 years ago
The downpipe is beautiful, the Empire State Building could only wish to have the same welds on this downpipe. Quality is spot on! With the ceramic coating I almost feel confident enough to lick the downpipe after a canyon cruise because of how much cooler it's kept. Installation is a piece of cake and make sure to get a tune since you're replace your OEM piping.

Great downpipe

GrimmSpeed quality at its finest. Strong build, very impressed with the welds and presentation. Easy install with all the required hardware included. I paired it with a Perrin exhaust and it sounds amazing. Very happy.

  • Q: Right Fit?  Random_Sloth 4 years ago

    Answer

    Will this downpipe correctly connect to a Invidia N1 Cat Back Exhaust Subaru for a 2006 STI?


    • A: As long as the catback uses a 3in flange at the downpipe connection you should have no issues. Mike
