Strange but true, I had a normal piston type Forge D/V which gave a nice whoosh/high pressure sound. Then I thought I would try a seemingly loud as fuŁk HKS SSQ....not so...it's actually not nearly as loud. Is there anything I can do?? ie screw at the back of valve.
BTW it's an earlier type(not bullet shape)
Any ideas appreciated.

 

Dont touch the screw at the back on the dump valve as it will cause idle problems..!!

There are inserts that come with the valve that make it louder one of them that comes with the valve is pretty quiet..

Mine is purple i think and has three triangle shapes to it..

Thanks Dan, however not sure if the parts are interchangable?

Dan, he said his is the older style one. They are open and don't have the interchangable heads.

Big AlT, get the ssqv (the one dan's on about), three changable sound inserts.
