- 2009 CWPM MS3
and it is uper beast honestly i love it..super sleeper when its shut and super beast when its open haha!
Very loud noise maker!
Given the high flow rate of the stock CBE on the MS3 (greater than the output of the stock K04 turbo's maximum exhaust output, I don't see how this would build any power, IMHO. Depending on where the cutout is located, it could remove the restriction of the second cat, but you can do that with a test pipe.
Yikes, that would be loud, I mean LOUD, but I would doubt you would see any performance gain.
There are a lot of cars that would pick up power, sometimes serious power, from use of cutouts, especially N/A American V8's with the cutouts right aft of long tube header collectors. Also, there have been some reported modest gains by use of cutouts on the MS6 (maybe 5 hp) because their system does have a bit more restriction in the CBE section, but it would be a hard sell for me, except as a very effective way to scare the unsuspecting pedestrian.
I do think it would be fun to play with, however. I can imagine having fun when being drowned out by someone's loud car stereo when stopped in traffic, playing music we just hate. We've all been there. Just open up the cutouts, raise the rpms to about 6K and watch the look on their faces!

I held about ~2 psi higher with the cutout open.
I had a Corksport DP and a PTP midpipe with the cutout fabbed into it. Stock cat-back exhaust.
The CS is catless. I ran a MBC holding ~18psi with the cutout closed, and ~20-21 with the cutout open with the same setting. The CBE is pretty free-flowing, but still a restriction compared to open air (1 or 2 resonators and some bends in there). I never had any boost creep issues.
