Exhaust Bypass Valve

[RoseBrawn]

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?

hi bro, where to install at J.B?
