Hi all,

I am just looking for some advice really i am thinking about putting a dump valve on my s3 but do dump valves on these engines increase or decrease performance? Has anyone ever had problems with dump valves on s3s?

I am looking at the twin piston bailey venturi dump valve, to be honest i just want the best sounding dump valve and these dump valves have the trumpet to amplify the sound. Any comments would be appreciated.

Cheers!
