Kleemann manifolds are not direct replacements. The manifold output flange is in a completely different location compared to stock and it is designed to mate up to the high-flow Kleeman cats which replace (cut & weld) the OEM primary cats.

That would be interesting and also what some others have said; that an x-pipe is not needed since we have that equalization tube in the resonator downstream. So, I am guessing the x-pipe gains might be from the removal of the secondary cats. But.... the only way to prove that is to run a DP with and without the x-pipes to compare. Oh well......
I can't thank you enough for getting this data for us.

Nah, it was all for the sake of research.
I'm sure you'll see the results you've been hunting for with this. But like some have mentioned, I'm a bit concerned about the ECU and whether it'll knock at WOT in high rpms. Maybe it'll adapt, but maybe it won't. Kleeman does tune pretty conservatively from what I've gathered, but we'll see how it copes with more freed up air flow. Other than that, everything looks to be golden! The "stupid loud" is a step down the right path.

C63 AMG Arctic w/ Stage 1 Tune, DoubleXX pipe, MCD-631X coming soon
It is nice to see this coming together Super. BTW, this particular project is Supers not mine, and this was Super's original idea, not mine, I just wanted to clarify this before any confusion, and I do not want anyone to think I'm taking undue credit.
I on the other hand have been beating myself up trying to build a modular solution, and making the male exhaust compression joint 100% repeatable in terms of production. We have played with various combination's from doing a CNC stainless billet end piece to buying a CNC expansion tool to swedge it up exact. I've had two companies working on this project simulatiously, big names (Bassani and Steve Millen Tube Works div.), not little BS guys. We have finally figured out how to conquer this, and I sign a contract for the first batch tomorrow, after the full prototype has been approved by me. I have NOT been dragging my feet on this project, I just feel that I MUST have 100% repeatable production, with NO slip ups like exhaust leaks etc. from an improperly formed male compression fitting.

I had that done to my c63, how ever i refitted cats (not the factory cats but aftermarket hi flow cats). I tried it with a h pipe and x pipe. To me, the car sounded **** with no cats at all. between 2300rpm and 3500rpm you will get this really bad sound (we call it thong slap in australia). It sounded terrible. Then i fitted x pipe, which quietened down the whole noise of the system but still had that **** noise between 2300 and 3500rpm. So i then fitted the hi flow cats which made it alot better. Yes i may have lost some power but not alot. If its for the track only, sweet, for every day driving i dont recommend it.

Like I mentioned before, I'll explore making improvements to sound via a swappable solution once I've got the baseline for power/torque.
Regardless, I will provide some 1st hand feedback tomorrow regarding tone, loudness and resonance after the system is installed. I have some experience around C63s with long tube headers and no cats. I have an idea what to expect.

Subscribed, thanks superlubricity. Do you see your fabricator producing more of these after you've done all your fine tuning. Btw, I heard those vibrant resonators don't do much for sound, HF cats are probably the best of both worlds.
