i have bought 1 of these 2nd hand from a guy who had it on a 370bhp sti and was working perfect, i put it on my standard wrx and i get nothing it just wont make a sound??? could this be because its for sti and no wrx ie:- i aint got enough power to push the spring.

i dont know much about them and have tried asking everywere i can think of, does anybody now if this is correct.

thanks in advance dave

 

Dumb question, but are all the pipes connected correctly and clipped/tied in place?

 

yeah mate, but if they wasnt i thought that wud make it just hisssss and leak, this is not giving no sound at all??? very very strange
