I have a blue wave that has an impossible to set spring relief valve.
I was thinking of fitting your fee flow valve but I couldn't find it in your store?
Do you still sell them and would you ship to the uk.
I did this some 8 years ago,
the bends are from a car intercooler system, 3" chrome tube runs into a cherry bomb exhaust that i have fitted under the floor.
it makes the machine a lot quieter.
Let me know if you need any more photos/info
:)after owninig my prochem performer 405 for six years, i have just picked up my brand new blueline blue wave truckmount.
lots more vac and heat only problem so far is noise, its much louder then the performer.
i am going tomorrow to have a s/steel exhaust fitted, i will let you know how i get on.
