• The Thing keeps the main exhaust pipe running at a constant pressure regardless of elevation or temperature.
• We are able to maintain a constant vacuum in the pipe; which dramatically assists the motor's ability to get more fuel above the piston for firing.
• We manipulate sound waves to achieve this process and thereby use the spent exhaust sound waves to assist in maintaining peak performance and power, no matter where you sled.
• All models of The Thing feature a polished ceramic coating or black ceramic paint.
• Our team can custom build this after can for almost any model of sled.

A two stroke motor has a tuned pipe designed to work for the particular dimensions of each motor size . these dimensions do not take into account what happens when the motor is not at sea level.

Example, the motor at sea level that has 150lbs of compression only has 120 lbs of compression at 7000ft.

Same motor down low has a pipe pressure at wide open throttle that measures say x lbs. same pipe at 7000ft measures the same loss in pressure that the motor does , due to the motors in ability to develop as much volume due to the thinner air.

Now with the pipe not running at the design pressure it is not helping the motor out as much as it could. Bring the pipe to pressure and the motor gets the full benefit of the pipes design. sound waves achieve the correct timing speed when the pipe is at its design pressure.

Our THING works with the manipulation of sound waves and has proven to be a very successful way to achieve correct pipe pressures over a very broad range of atmospheric conditions.

Each motor size and shape requires a different set of dimensions to achieve the correct correction of pressures. Entrance and exit points on a chassis is another side of what the end product ends up achieving and what one THING may look like in the final results.

We offer a 2 year warranty on the packing and cracking. As well we offer the customer a trade back value on their can. Find yourself changing sleds, just call us and we will outfit you with the correct one for your new model allowing you some money on your old one.
