Im running a BBK Off Road X Pipe with Steeda Catback and stock headers.Im wanting to replace the BBK ORX.I have had it on the car since i got it. Im over the leak at the manifold and the extra raspy sound it gives. Im wanting to replace with the Mac Prochamber ORX or Mac ORX or UPR X? If i happen to go with the Mac Prochamber especially or another xpipe should i worry about a retune?
