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 Converters w/Muffler Delete X-Pipe
• Catalytic Conv. ByPass Pipes w/X-Flow Muffler (for off road/track use)
• Catalytic Converter Bypass Pipes w/ Muffler Delete X-Pipe (for off road/track use)

Our modular design incorporates Accuseal clamps 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 20 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 German HJS Hi-Flow catalytic converters will improve the performance of your Porsche 997TT by enabling 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.

SOUND - The SpeedTech X-cellerator cross-flow system emits a fantastic GT3 type note and is available in four sound levels to suit a variety of tastes and uses:

• 2.5 Muffler (conversation, phone calls, radio are all very comfortable, just slightly louder than OEM).
• 2.5 X-PIPE - Eliminates the Muffler all together for a fantastic exotic sound. Moderately louder than OEM. Very comfortable.
• 3.0 X-Pipe - "OUR TOP PICK" for the 997.2TT. A sportier version of the 2.5 X-Pipe - designed to provide an aggressive, yet refined sporty exhaust note. 3.0 Sport mode is glorious, while standard mode is very comfortable and refined. Best of both worlds! The 3.0 catless RACE version screams and wails with all he right turbo whistle sounds (see video)!

If you desire a louder, more aggressive sounding system, the 3.0 X-Pipe is the best choice! The assertive tone on start-up is followed by a fantastic wail at WOT.

We offer a lifetime warranty of manufacturing defects for the
original owner.

The SpeedTech X-cellerator is designed, tested and manufactured in the USA .
