We've been working on tips for the 991 (and 997) for the GT3/RS. We have 4 styles that have made the cut. They're all made from 321SS and are interchangeable. We've made them modular so that you can change them without removing the muffler bracket.
In addition to the 4 in 321SS PVD Coated Black, we have them in polished Ti with a flame treated edge
The 321SS PVD Black Tip set with frame, clamps and any style tips is $545.00 Intro Pricing

Do these tips come out as far or further than the OEM tips? Reason I ask is because I want to get tips that come out a little further so my bumper and license plate frame don't melt (from when I'm tracking).
The megaphone tips do a bit, had 4.5" megaphones (they look a bit like an ACME rocket booster from Road Runner fame) on the GT3 on the dyno today testing a theory and they actually add a bit of HP as well, 3-5whp... in some spots. More to come on that.

are you building any baffles or other suppression in the turn down pipes?
Can't restrict the flow, if you need less volume, that's better done in other ways... So turn down only. We've designed a Laguna Seca muffler that would cut down sound levels a bunch, but isn't so nice hanging off the back of the car...
