Hey peeps. Ive had a search but nothing really helping me. I got my self a forge split r dump valve from ultimate dubs. Ive fitted it and messed with but im not getting much of a noise, just a little sneeze only from inside the car. Im running a standed air filter would this need changing, or do i just need to mess with it some more. Valve come without the box or any info.
Cheers
