Will be getting my GT3 up in the air mid week after th GT4 Race headers are finalized! Shouldn't be long now! Also working on a solution for the occasional CEL that is possible with our race system.

Are you using your stock exhaust box? Or you also got Akrapovic slip ons?

Did you get the catless headers? Do you have it with the side mufflers?

No side mufflers in with the Dundon Race System. Headers, side deletes with valves to the stock muffler.

Oh I like that. How much louder is the catless version vs the cat version?

How about a group buy when the catted version comes out for us new crop of RS owners?

I'd expect the catted to be a little quieter than the catless but not by much. We're working on rev 2 of the catted 991 stuff first part of next week. We can absolutely do another group buy for the 991 GT3/RS guys that are interested.

I saw you had a set of the cat-less on insta, are they still available? If there is going to be a group buy price I may wait though... not digging the SW center section sound on my RS, it was great on the GT3, but doesn't sound as good to me on the new car.

We do have 2 race systems ready for delivery. Shoot me a PM and I can get you rennlist pricing.

We will be offering intro/GB pricing on the catted system once finished!
