Message: <blockquote data-quote="SentraVIP" data-source="post: 2494283" data-attributes="member: 33682">Hi guys, there's seems to be a problem with the design. Imagine the 'valve' is closed during had acceleration. The exhaust pressure will push the 'valve' open in no time, IMHO. You'll need quite some force to hold it in place. Not to mentioned how hard it will be to work against the exhaust flow velocity to close the valve in the 1st place.I think that's why those Apexi design it like throttle bodies. If the axis is in the middle, the positive pressure (exhaust gas flowing out) and negative pressure will cancel each other out and makes it more easily operated, IMHO.Thinking along the lines, why not just get a rosak throttle body and fabricated/custom mount it into your exhaust?IMHO, the smallest of throttle body's inner diameter will be much larger than any normal exhaust application (be it NA or slightly boosted). Another reason is that it already comes with the springs retainer (to shut the valve close by default). U just need a cable which is long enuf to route it back to the cabin via the firewall?Just my two cents</blockquote>
