Stock rubber hoses and cast pipes will be replaced with the polished aluminum SQV pipes that have smooth shape. Although the default blow off valve layout returns to suction pipes, by replacement with attached fins, high frequency blow-off sound can be enjoyed. There is no engine stall problem with the kit.
