You already have a dump valve. It recirculates air to just aft of the MAF sensor on the air intake.

If you are speaking of an atmospheric dump valve aka Blow off Valve (BOV) - then I believe you will need a blanking plate to remove the recirc valve and a twin piston BOV.

This has been covered many times - so use search to look for BOV
