After seeing how snug everything is I have some install questions.
Removal of transmission necessary?
Cutting of stock piping necessary?

Excellent work and great sounds

Thanks for the kind words guys

As per the installation, yes the transmission needs to be removed in order to remove the stock pipes AND install the new ones. I do not want anyone getting the idea that you can cut out the stock downpipes and somehow slip these in.

As long as you remove the tranny, these will bolt up directly to the turbos and directly to your factory mid section with all supplied clamps and hardware.

Do you have dyno tests to demonstrate power gains with and without a tune?

I do, but the calibration is for VP Fuels MS109 which wouldn't help anyone unless you are looking to run race gas 100% of the time like this car is.

Once we got Kingmonkeys stock downpipes out, we were able to put them next to our ACG downpipes. This really illustrates how restrictive the stock downpipes are.

Would just be the photos and especially the factory heat shielding that makes it appear that way.

The stock piping inner diameter is a little bit over 2.5" and our stainless replacements are slight under 3" inner diameter.

E63S ED1 Tuned + Wheels, new A45S on its way
I have an Edition One Coupe C63S, arriving mid November. I am in Australia, everyone here seems to be running the same Akrapovic, cat back Ti system. I run an Armytrix full system, Turbo back on my facelift A45 which sounds clean and powerful. I leave the valves open 100% of the time and the crack and pops and bangs are for my tastes perfect. The Akrapovic systems I have heard are muted by comparison.

Very interested in your downpipes, what system do you recommend fitting after them?

I assume you get an ECU check light once you remove the downpipe cats? Unless you do an ECU reprogram?
