yeah i am selling my turbo xs h34 blow off valve, i is a reciculatory blow off valve, it vents back into the intake, which means it makes little to no sound but still serves its purpose for a bov...i only used it for about two days and then put the stock one on till i purchased my new one today a turbo xs- H RFL the h34 retales around 150 so i will sell it 100 buck with shipping included in that price....if anyone is intrested let me know.
