Too often companies bring products to the market prematurely. Whether it is cutting corners in production or poor customer service, we've seen it all. Installing hundreds of components in all categories every month, it is not uncommon to find inconsistencies that the customer would not think or expect. When we first started working with Keller Performance on the F90 chassis, we quickly realized that their focus was prioritized on quality. They are manufactured with the highest grade T304L & 310 stainless steel, TIG hand welded, added solid liner flexpipes, CNC flanged, factory placed mounting brackets, and mandrel bent for flawless fitment with every single set. They created their set from new OEM F90 downpipes, which were 3D scanned to ensure fitment was identical to factory. They worked with us for countless hours both on and off the lift to bring the best primary and secondary downpipe option to market. Their production is now in full swing and orders are ready to be met. Contact us today via private message, email or phone to get yours shipped to your door, or installed here in house. Now onto the pictures...

Ugh am I the only one that doesn't like the sound of Akra exhausts? Never heard one I liked, always seem too high pitched to me. Could be the DP adding to that sound though.

Still no one makes sport cats for these cars........

It does sound better but why can't bmws 6 pot or v8s sound anywhere near as good as Amgs? As mentioned they do sound a higher pitch.

I know turbos mean it's difficult to get a deep v8 growl but the higher pitched and crackles just don't do it justice to me. Drive by sounds better mind.

Agreed. I never cared for how the S63 engine sounds at all. It has no rumble or roar like a V8 is supposed to. It's just loud and unrefined, with no character at all. I mean it literally sounds like a boxer 4 engine from a Subie, just two of them.

Especially the f90 platform, besides the fact that exhaust note isn’t as refined as let’s say an AMG 63, the car itself is so insulated, We felt that primary and secondary downpipes added so much character to this car as it should’ve been from factory.

Always a bonus, but... when have you ever seen a catless downpipe fail?

Good that you mentioned it... but didn't need all the excitement around it. Lol.

Do 200 cell sport cats that don't throw a code... and you got me. Reasonably priced of course.
