The CMS exhaust sounds a little deeper and lower than the GMG. I cannot speak to any HP gains because I have never measured them. I buy the exhaust for sound since Porsche did it right with the HP. Anyways, any gain in HP is usually not noticeable in my opinion.
Bottom line, I wanted to try something different, something new, something made with utmost quality (I pay huge attention to detail and like to think outside of the box).
911_RS, the GMG exhaust is awesome; I've tried it. The CMS exhaust is awesome too.
Don't bash something without trying it out or seeing/hearing it. This is just another option for our phenomenal cars!

I have had GMG on all my GT cars except this 991 RS where I decided to try CMS knowing I could return it (no questions asked) if I didn't like it. I didn't even know this product existed; since I buy my wheels, tires, brakes and brake fluid from CMS I thought I'd give it a shot.

No doubt it sounds amazing, I'm sure it does!

More video...
In case you're wondering how scavenging works, here is a video to show you. Compressed air blown into one side actually pulls the torch into the other side. Isolated outlets do not, while a balance tube will actually blow out the other side.
As we've said, form follows function -- that's how you unleash incredible sound and make power.

What's that saying.....
Lastly, I didn't want to respond but when it appeared that some were questioning our design, I wanted to at least respond......
I asked PMNA about this and they have never instituted merging rear tips in their race exhausts as they want them separate.....like on the Clubsport, Cup, R and RSR.....

I would be shocked if there were any HP gains more than 3 - 5 with this system or ours.....I like that even our plate was copied......
