The Titanium muffler and header package has taken my 3RS to a new level. I have often received comments at the track saying that my car is the best sounding car at the track.

Perfect balance of sound and performance. My car walks away from other 992 GT3s on the straights and sounds spectacular. Noticeable difference in on track performance.

Incredible sound. I installed a full Dundon system on a 992.1 GT3 Touring.

Sounds normal stock until it doesn't... Cold start won't wake the neighbors but as soon as I put it in sport mode, things change. Also in normal mode if I go above three or 4000 RPMs the valves open up and all hell breaks loose but in a good way. Higher pitch Sound no drowning very solid no regrets. Take that card to 6 to 9000 and we have problems in a good way.
I was concerned about putting the loud inserts in but after talking to the guys over there, they said they have not had one client take them out after they received the install. Glad I have them. It's not too loud and it's got a great pitch to it.
