Performance Exhausts & Accessories
Porsche 996 Carrera "Sport" & "Sound Valve"
Exhaust System (1999-2005) 3.4 L, 3.6L
We offer two muffler styles for the 996 Carrera. A "sport" exhaust and a "Sound Valve" exhaust. Both provide a more aggressive, sport sound when compared to the stock exhaust.
The "Sport" version provides a very tasteful, exotic car type sound, developed for the enthusiast, so that you can really enjoy the sporty sound your 996 Carrera is capable of...
The "Sound Valve" muffler is designed to offer the best of both worlds, i.e. - stock-like sound (just a bit louder than OEM) when the valves are closed and a very aggressive, exotic race like sound when open... like we say, it's the "The Best of Both Worlds"! This version includes a key fob wireless remote and all vacuum lines, instuctions, etc. for a complete installation.
The enhanced exhaust note of both these systems are very tasteful with an exotic car type sound. We developed these systems with the enthusiast in mind, so either system will allow you to truly enjoy the sound of your Porsche 996!
In order to maximize performance and improve throttle response, both of these muffler systems are manufactured with a free-flow design and we offer high flow catalytic converter mid-pipes or "catless" RACE mid-pipes, as well as performance headers in order to achieve improved performance.
The SpeedTech 996 Exhausts fit all 1999-'05 996 Carreras (3.4 & 3.6L). Note: For the 996 GT3 we have a complete GT3 exhaust system with catalytic converters available, however, the standard 996 mufflers shown here can be used on the 996 GT3. Mufflers only for GT3 (no 996 mid pipes or headers).
For maximum performance gain, we recommend installing our headers and mid-pipes with our muffler. For a more traditional sound, use the OEM style individual Mid-Pipes. For a higher pitched, more exotic GT3-like sound, select from the X-Pipe options. Catless RACE pipes are for off-road or track use only.
We offer a lifetime warranty of manufacturing defects for original owner.

Muffler Bypass Pipes
996 X-Pipe w/ Cats - Just a quick note to let you know that I had the x pipe installed today and am very happy with the results. The sound is smooth like silk, and seems to integrate well with the cans. The difference in weight is amazing, I am guessing the weight of your x pipe is less than half of the OE system. Once again, thanks. Larry S., CA
Love the mufflers. Great sound. Can I have a set of headers? John A.
996 X-Pipe - Some weeks ago I ordered a Speedtech X-pipe catted system. John was prompt with his replies (on a Sunday in my case) and very helpful walking me through my order. After fabrication, the pipe was shipped and arrived at my door in Canada only days later.
As my C4S is a daily driver, a lot of the bolts etc were extremely rusted, so had my indy do the install.
Aside of taking extra time to remove the old cats, the system went in flawlessly. New O2 sensors were installed too (old ones were not coming out). The result: absolutely awesome. The system is nice and quiet at idle and low rpm and livens up 3500rpm and up. Not over the top, but you surely know it's there. Shoukd have done it years ago. Job well done by John and Speedtech team. It leaves me as an extremely happy customer. I can highly recommend them.
