I'm just now getting my 914-6 GT replica running and will likely be using it for track day events and some street use. It has 2.7 CIS conversion with a Tri-Mil muffler (dual in single out) and headers. I'm looking for a muffler with more sound and exhaust flow. Any ideas on options or recommendations?
I've use a LOT of mufflers/exhausts over the years, though my 914-6 (also a 2.7) usually has open megaphones for track. Since it's street driven a bit more lately I recently went with a Dansk 2-in/2-out stainless RSR type sport muffler (from PMS). It sounds fabulous but is heavy and expensive. Car seems noticeably "happier" (less constipated) than even with a special 2-in/1-out 92mm Dansk sport muffler I had before, though no before/after dyno. I really prefer the look and (louder, throatier) sound of the wider RSR pipe design over the conventional 911 2-out sport muffler.
Have a seat before looking at the price:

I have tried Bursch and Triad previously as well but frankly was not a fan of either.
Have heard good things about SCART as well but no personal experience.
