I was looking online at this westcoast tuned pipe and on the top of the picture there is a small canister/valve? Any idea what its used for? I cant even find west coast website .
Picture is too small to see what it is. West coast had a water regulator that was mechanical... it could be that.
As far as finding a website for them... isn't goin' to happen. They closed their doors in the mid 90's. They made some great stuff... but they were a little overpriced.
Back in the day... I had a West Coast JS440 practice ski. It was one of the fastest stand-up skis I ever rode. (until the 750 and 800's came out)
