For those looking to take the finest downpipe one step further and wring out every last ounce of performance, GrimmSpeed offers teir '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.

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 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 hand off 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.

Not as pictured but they made it right!

Ordered this downpipe believing it had the o2 bung after the cat as in the picture (at the time, but since updated). When it arrived (only a few days later) it had the bung before the cat and according to my shop, would still cause me trouble with CEL’s. I contacted Subimods and explained what had happened and they honored the fact that the picture was incorrect and of an old version of the DP according to GrimmSpeed. Subimods sent me a label for return shipping and the customer support was great to work with. I have since ordered a new GESI DP with a post-cat o2 bung and am awaiting its arrival. Thanks for handling this efficiently and professionally.


Thank you for your positive review! Unfortunately as products are updated and changed we are not always provided the most recent pictures! We do appreciate your understanding of this and I am very happy to hear Subimods Customer Support was able to rectify the issue, not only by changing the picture but by getting you the proper GimmSpeed Limited Series Ceramic Coated Catted Divorced Downpipe! You will not be disappointed with the 304 SS construction and less restrictive free flowing design! You will notice the difference in response!
