Introducing the Mach 2 Bypass Valve

If you're looking for a fantastic upgrade for your turbo model, the Mach 2 is here to impress! Just like the Respons and Deceptor Pro II, the Mach 2 comes in a variety of bolt-on kits tailored for most popular turbo models. And when we say "bolt-on," we truly mean it! You won’t need any extra adaptors, parts, or vehicle modifications. Just pop off the factory bypass valve and replace it with the Mach 2—it's that easy!

Versatile Configuration Options

The Mach 2 is designed as a 100% recirculating valve, which means it works perfectly as a bypass or plumb back system. If you’re after a direct factory replacement that delivers performance without the noise, stick with the recirc model. But if you’re in the mood for a little sound with your performance, you can grab the conversion kit for 100% atmosphere venting!

Say Goodbye to Common Issues

Factory bypass valves often come with a couple of drawbacks. They usually start opening at a certain pressure to protect your engine, which can be limiting. Plus, they aren't optimized for quick throttle response. And let’s not forget, you can’t vent them to atmosphere without risking a stall!

The Mach 2 Advantage

The Mach 2 is here to tackle all those problems head-on. It can hold unlimited boost—yes, unlimited! No turbo could ever generate enough pressure to damage it. Thanks to TMS technology, you’ll enjoy maximum throttle response. And with the atmo conversion, you can vent to atmosphere without stalling your engine. How great is that?
