Exhaust Bypass Valve

[starscream]

Anyone tried using one of these? Open up the valve will give a noisy ride but improve in power and closed it when you need a silent ride, but what are the problem known after installing it? can the electric motor stand the heat of the exhaust? All the sifus please advice.

in most cases i've seen they use vacuum activated valve or cable activated valve...
motorised activation so far havent come accross yet... unless branded ones such as HKS and other brand, they might have it...

other brand such as arospeed also using cable actuated valve.... (if not mistaken)

Thanks for the advice bro, Thinking of putting in a evo fuel tank and run a Tee at the end, one connected to a original perdana muffler, and the other the bypass valve, so i can have both extreme silent ride and least back pressure when i need it.

i saw a local shop at jb selling it, i think they did it themselves, priced at RM900 but only for NA, i think is too expensive so din consider it. What is the price for similiar product?

And if i changed to a bigger diameter piping, using sillent muffler will cover back a bit low end power right? is it a good choice of bigger diameter exhaust + bypass valve?
