I used a 90 degree bend preff the smallest you can get a away with fitting and then used a small peace of tubing maybe perhaps ... 5 inches long bout 1'' 1/2 wide , then a cotton filter
Nope no damage can be caused in IMO ive seen 350 - 400 bhp cossies, FRST , Pulsurs and Evo's running with out a DV and they dont have issues ,
Personal choice in my Mind ! , I go for the Compressor surge noise , :wink:
