Porsche 996 TT / GT2 SpeedTech X-cellerator Performance Exhaust

The SpeedTech X-cellerator cross-flow exhaust was designed to offer the discerning Porsche enthusiast the ultimate exhaust system with a number of performance and sound options in one complete package. CROSSFLOW or X-FLOW DESIGN - By combining the exhaust pulses from both sides of the Porsche boxer motor with an "X" or "cross-flow" at the center of the muffler (internal crossflow design), we have developed a unique, exotic sound that has to be heard to be appreciated. Our trademark sound is well known and highly respected throughout the industry. DESIGN OPTIONS - The X-cellerator system includes catalytic converter bypass pipe and muffler bypass pipe options resulting in four possible exhaust configurations: Catalytic Converters w/X-Flow Muffler Catalytic Converter w/Cat Bypass Pipe No Catalytic Conv. w/X-Flow Muffler (for Race use only) Important Information:This product is for Racing Competition use only and is not legal for use in highway or street vehicles or other non-racing competition off-road vehicles. No Catalytic Converter w/ Cat Bypass Pipes (for Race use only) Important Information:This product is for Racing Competition use only and is not legal for use in highway or street vehicles or other non-racing competition off-road vehicles. Our modular design incorporates V-Flange couplings for quick and easy swaps between the various sound and performance levels. This versatile design is very easy to use and offers quick installation and/or swaps. PERFORMANCE - The SpeedTech X-cellerator cross-flow system eliminates approximately 25 pounds of weight (full system w/ cats) compared to the Porsche OEM exhaust. Additional weight savings can be realized with use of the off road configurations. Whether lap times or straight line speed is your goal, the weight savings will help yield quicker track times. Additionally, our free flowing, straight through design, along with proprietary Hi-Flow 100 cell “race” catalytic converters will improve the performance of your Porsche 996TT. 100 cell catalytic converters offer the extremely quick turbo spool, along with increased torque, higher horsepower and much crisper throttle response! Faster track and ¼ mile times, better everyday performance and the pronounced engine note will provide an enhanced driving experience for all types of uses. All components are constructed of T304 stainless steel and the muffler is packed with stainless steel wool for years of trouble free performance, even under extreme use conditions. This is a very well built, top of the line exhaust system for the discriminating enthusiast and very fitting for the Porsche turbo.TIPS - We offer several tip options to appeal to a variety of tastes. Each tip option is pictured to the left. They include: Standard SpeedTech mirror polished, dual wall, 4” round tips w/rolled edge, slant cut tips. Dual wall design eliminates permanently stained/discolored tips, like less expensive or "shortcut" systems use. Our standard tips maintain a shiny, show car like finish forever. Perfect for show cars! And we do not charge extra for this upgrade. N/C Option: Re-use OEM tips (twin style only) SpeedTech dual twin tips SOUND - The SpeedTech X-cellerator X-flow system delivers a phenomenal, exotic, high end car sound that the majority of Porsche owners desire. Many of our customers have tried several other exhausts (some up to 5) before falling in love with the SpeedTech X-cellerator system! It has received numerous unsolicited accolades many of which are displayed on our testimonials page. The bottom line is that this system sounds fantastic and offers all options one could desire in a performance exhaust. It is available in either a full 3” version (loud) or a 2.5” muffler version (quiet). Both exhibit our trademark internal X-Flow GT3-like sound.2.5 - Our 2.5 quiet version is extremely quiet in the cabin while cruising at low RPM’s 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! A straight X-Pipe is also available. 3.0 - If you desire a loud, aggressive sounding system, the 3.0 version is for you! 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. Please take a moment and listen to our videos and hear both systems for yourself.
