Anyone used one of these remote exhaust valves? I've emailed the company to see if they are able to do a 2 bolt flange so it could be fitted on a Toyota between the mid pipe and back box.

Good find dude, no need to ask for 2 bolt as they would need to tool up, prob easier to ask if they can supply the matching 3 bolt flange to weld to the exhaust, I might try one of these on the Black 'stealth' car I have.

The QTP Electric Cutout and Sound Performance Boost Activated Cutout are designed as bypass valves and the flapper valves form a complete seal.

The Apexi Exhaust Control Valve is designed to fit in line to reduce the noise level of the exhaust, the flapper valve is smaller than the pipe diameter to allow the exhaust gasses to flow around it. The QTP and SP could be used inline the same as the Apeci ECV but would need the flapper valve reducing in diameter or stopping it from completely closing.

That's the way I did mine - total bypass option, and it works well - mine is a DMH valve though. I thought about boost activated but the downside is there's no chance of a loud rumble at idle as you can't open it on demand :D

It does not go in the exhaust, you would fit a y pipe and it goes on the 'off branch' no car will run with a blocked exhaust, go stick a potato in your neighbours exhaust and you will see !!!
