Tail bov 50mm
I run this on my tta
It will wake you up when it sneezes
It dont not have delay lagg when back under boost
Its a few bucks. But its worth every penny

I like the bosch turbo bypass bov 0280142110 one that is very quiet and can be found super cheap used on ebay
it also has accomodations to tie back into the air box so it works well with the MAF sensor
I paid $30 for it. You will need the 3/4" NPT MALE STRAIGHT TO 1" HOSE BARB NIPPLE ADAPTER $7 and the 3/4" female npt aluminum weld on bung fitting adaptor $8 and 3/4" hose from advance auto for $1.50
total investment $46.50
