SR has a bypass valve stock, which is the same as a blow-off valve except it recirculates the air back into the intake tract. This is to avoid the bogging and stalling that you'll sometimes get with a BOV that vents to atmosphere. Meaning, it's the better choice if you're mainly concerned about having your car run and perform well.
But, if you're really concerned about sounding super cool - and it sounds like you are - then go find an HKS SSQV.
