Speed technologies over the years have become the leader in providing the daily 700hp plus driven Porsche 996tt with the proper exhaust and accessories. With 20 years of experiences, the result is a line of superior performing exhausts for a variety of Porsche automobiles.

Speedtech has just released their new system of exhaust design with the x-cellerator cross-flow exhaust system. The cross-flow designed to offer the discerning Porsche enthusiast the ultimate exhaust system with a number of performance and sound options in one complete package. The cross-flow designed by combining the exhaust pulses from both sides of the Porsche boxer motor with an x of cross-flow at the center of the muffler. Also they developed a unique, exotic sound that has to be heard to be appreciated.

Speedtech x-cellerator cross-flow system saves approximately 25 lbs of weight (full system w/cats) compared to the Porsche OEM exhaust. It also incorporates their free flowing, straight through design, along with increased torque and horsepower.

The design is constructed of high quality t304 stainless steel and the muffler is packed with stainless steel wool for years of trouble free performance, even under extreme use conditions.

Options to choose from:


Sound preference:

2.5 quiet version is extremely quiet while cruising at low rpms and allows for easy cell phone usage, conversation and music enjoyment. Yet under acceleration it emits a very sporty, wonderful tuned sound. A perfect combination and aggressive enough for the majority of turbo owners! When optioned with the muffler bypass pipes, the 2.5 becomes a lightweight, full 3 straight pipe system for track use!
3.0 is for the enthusiast who desire a loud, aggressive sounding system. The assertive tone on start-up is followed by a dominant cup car like wail at wot. A true race car sound for the street. The full 3 design will provide unrestricted flow, even on the most powerful built cars, as well as a stock car.
