Speed technologies over the years have become the leader in providing the daily 700hp plus driven Porsche 997tt 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 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 pounds of weight (full system w/cats) compared to the Porsche OEM exhaust. It also incorporates their free flowing, straight through design, along with proprietary hi-flow 100 cell race catalytic converters will improve the sound and performance. The 100 cell catalytic converters offers a quicker turbo spool possible, 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: (below)

Sound preference:

2.5 quiet (conversation, phone calls, radio are all very comfortable, yet the exhaust still provides a great GT3 type sound on the exterior). A perfect daily driver system.
2.5 sport (a little louder than the quiet version, but still very manageable). Also a good daily driver with a fantastic wail at wot.
3.0 moderate (cell phone calls begin to be a little strained). Aggressive tone due to 3 muffler internals.
3.0 loud (a full 3 system that screams at wot. Phone calls are even more difficult, but still possible. This exhaust is definitely being heard in the cabin and all around outside) sounds awesome/very aggressive both inside and out.
