Spoke with GMG about their exhaust, here are my findings (info on tips).
 

The pictures you see are of their prototype, so its not the final pice. This is verbatim what I was told about the tips:
"The production version will have a beveled edge so there will be a lip on it."

They will have their testing of the new system done in 3 weeks and sound clips soon as well.

I'm inclined to get it if the tips look good and it sounds good. It maintains a single tip per side and it costs less then milltek. Plus it's supporting a smaller california company who races in the speedwc.

just don't have them install it for you, it will cost a few hundred dollars
 

a corner balance there runs around 1,000$ from what i have seen on a couple of invoices posted on ebay when Porsche guys were selling their cars

My dealer will gladly install an aftermarket exhaust if you are willing to pay
 

and keep your warranty intact. Pay to play I guess and I would rather have piece of mind with all the horror stories of dealer issues with mods all over car forums.

I would love it if it were valved -
 

I want smooth and angry in the same package :-)

Kind sir please get your facts straight .... before posting
 

A corner balance does not cost thousands..??

And the fact of the matter is that depending on the suspension and its adjustability particularly on a Porsche the work is involved and very time consuming.

But then again, you already knew that didnt you...



I can assure you that a corner balance does not cost thousands...

So do everyone a favor and dont post incorrect facts ...
