Quick Time Performance
Wouldn’t it be great if you could control the volume of your exhaust sound as easily as you would your car stereo, well now you can: up until now there was no way this was possible because once the exhaust has been fitted to your car that’s it, the only way to raise or lower the sound was to change the mufflers, certainly not a cheap alternative. Exhaust valves are the answer.
What is an Exhaust Valve?
An exhaust valve is an electronic component that is installed professionally in the exhaust system at a suitable point and allows the driver full control of how the vehicle should sound by way of a switch or remote control unit, have the vehicle whisper quiet as the current exhaust or wake up the town, the choice is yours at the flick of a switch.
Which Exhaust valve is best?
There are many exhaust valves on the market and obvious leader is manufactured by QTP Performance, as the most reliable, we have been fitting valves for many years and the QTP is by far the best, cheap alternatives, either lock open or lock shut leaving you in an embarrassing position, worst still cheap alternatives rattle annoyingly, we have also seen these valves fitted inside mufflers but when they go wrong the whole system has to be changed.
More Size Options than any other Cutout on the Market!
Kits are available for any application from classic cars to muscle including high tech imports. Sizes range from 2.25″, 2.5″, 3″, 3.5″ and 4″ there is also a Low-Profile Oval Cutout available.
To see how little this futuristic modification can be just fill in the quick quote form:
The QTEC is designed to relieve back-pressure from your engine by diverting exhaust gas before reaching your muffler system. Allowing for more power and better sound. The QTEC is 100% adjustable using the control switch so you can have as much (or as little) sound as you like.
QTECs are available to fit most cars or trucks. With sizes ranging from 2.25″ through 4″ on our standard size cutouts. If your car is lowered or is tight on space, we offer our Low profile system, which allows for increased versatility on install.
The QTEC is effective anywhere between the catalytic converter and the muffler. As a standard rule, we recommend placing the cutout at least 14″ behind a header collector. If you have a newer vehicle and it uses a resonator, this will ‘muffle’ the cutout so placing the cutout before the resonator will help deliver maximum sound. Ground clearance should always be considered and you should plan to leave space between the bottom of the vehicle and the QTEC mounting location to allow for space for your exhaust system to flex under heavy acceleration.
The QTEC is designed for racing/off-street applications. With the electric cutout in the closed position, your vehicle will function just like stock however your local laws may vary and you are encourage to do your research with local motor vehicle laws before making any purchase that modifies your vehicle.
The QTEC is designed for years of trouble free operation. Just like any other component on your car, you cannot install them and ‘forget’ about them. Exhaust systems will generate soot and over a period of time that can clog the sealing surfaces of any cutout. We recommend, monthly spraying the cutout surfaces with a good penetrating oil such as “Liquid Wrench”. WD40 is not recommended in this application, as the water content tends to cause evaporation. If you drive your vehicle in harsh climates or the valve is exposed to winter road conditions, we recommend removing the Electric valve and using the supplied cap, close the system off until more favourable conditions are realized.
Absolutely. We realize accidents happen and sometimes that day at the track didn’t go as planned. We offer a full compliment of replacement parts for our cutouts. You can find replacement parts
