valve question

does anyone plumb there dump valves into the exhaust so you cant hear the dump noise?  if you have, is it worth it?

i wouldnt recommend it.  inside the valve there is a rubber seal. the seal keeps the air in the bag. i think that the exhaust from the car would get too hot and back feed into the valve body, possibly causing the seal to melt. then your truck would lay out.  you can buy valve silencers, they are real quiet compared to an open valve. 

just sounded cool.  didnt know if it would work or not.  would prob have to run copper a couple feet from the exhaust to the valve.  plastic line would obviously melt.  thanks for the reply and info.

valve silencers are plastic so i dont think a plastic line would hurt it  

The dump silencers I have are Parker 3/8, all brass,no plastic!
