Increase HP/TQ and activate a full race exhaust with the flip of a switch, with our ECS Vacuum-Actuated Exhaust Cutout.

Please measure your exhaust outside diameter, before ordering

If you’ve been shopping for a freer-flowing, louder exhaust system to enhance power and sound but are concerned about all the drawbacks, the ECS Vacuum-Actuated Exhaust Cutout is the perfect solution to have it all!

Keep your original, peaceful exhaust system for comfortable, daily driving, then flip the in-cabin rocker switch for a FULL RACE exhaust system to increase horsepower, torque and sound! Experience the FUN of driving with our exhaust cutout from the moment you flip the switch! You’ll have head’s turning every time you open the valve.

Designed and engineered by our in-house Engineering Team, we spec’d out a unique vacuum-actuated exhaust valve for it’s integrity and durable operation. Rather than using an electronic valve, our pneumatic actuator is less prone to failures and other corresponding issues that plague electronic-driven exhaust valves.

PART DESIGN

Exhaust Cutout and the included Exhaust Clamps are T304 Stainless Steel for corrosion resistance

No welding required, can be installed in your driveway using basic tools (grinder w/ cutoff, sawzall or hand-held exhaust pipe cutter along with standard socket/wrench set)

Compact design, requires very little space, and exhibits excellent flow characteristics

Turn down tip provides a clean appearance, great sound and keeps exhaust soot directed towards the ground

Requires ~8in/Hg of manifold vacuum to open exhaust valve

Vacuum actuated, requires intake manifold vacuum source for activation

No loss in ground clearance (dependant on install placement)

PERFORMANCE FEATURES

By eliminating major restrictions in your exhaust system and allowing your engine to breath with greater ease your engine will develop more power with a wide open exhaust note to go with it!

PRODUCT DEVELOPMENT

Our R&D Team tested multiple designs on several vehicles to ensure only the highest quality Exhaust Valve is delivered to you. With tens of thousands of combined miles in all driving conditions, including harsh winters with salty environments, we can confidently provide you with a durable, performance solution.

INSTALLATION AND SUPPORT

Be sure to check your local laws and regulations before purchasing this exhaust cutout. This is intended for off-road use only!

REQUIREMENT: Intake manifold vacuum source needed to activate exhaust valve. You will need to tap into an external vacuum source or purchase of a boost tap, depending on engine configuration.

With our compact design only 12.5″ of straight tubing and approximately 9″ of available width is needed for intended installation. Flared ends allow for ease of install and minor mishaps for cut length. Can be installed in your driveway using basic tools like our Schwaben hand-held exhaust pipe cutter – ES3106581.

Please measure the outside diameter of the exhaust tubing at the intended installed location. Our cutout slips over the exhaust pipe for a clamp on installation.
