yes its true
ive seen them at halfords and cant believe it!
why bother?
its not a dump valve, its a speaker with a switch that fits
on your throttle somewhere lol, im not joking either.
i like the sound dump valves make lol,but i dont
have one anymore and the electronic dump valve is just one
more reason why.
i used to like mine as i drive a cabby with an rs lump and it used
to make people wonder when it went off but they would probably
just think im some dick with a fake one now.
