IMO it's the best sounding muffler for air cooled 911's I've ever tried. However, for bigger motors like the 3.6 - it's not the most effective.

Amazing! Thanks for sharing. How deep, or not, is the tone? I know our cars aren't six liter V8s, but I tend to prefer basso profundo to screamers, when it comes to exhaust tone.

I am in Brian's queue for a set of headers and his Active Exhaust, Split Secondary System for a GT3 box. Unfortunately, I still haven't found the GT3 box. I am going to run his 2 in / 1 out muffler in the interim, but the search is on for a GT3 box!

Anyone have a line on a 997 titanium unit? If so, please let me know.

Why do you say it isn't as effective on bigger motors? GT3s have bigger motors and the rear box is one of three mufflers in that system?
