I Did this mod and its great, but something came loose and I lost the seal somewhere. I plan on getting the fender off and doing it again since I got the ram air vent.
I ran a 2 inch pvc and then went to 3 for the vent. but I need to upgrade the pipe, I bought a ram air vent off of ebay and I have to use 3 inch and then 4 inch for the vent.
