I'm currently running a janspeed stainless steel cat back with a decat but want to be able to put my cat back on, my decat and cat are different sizes so I can't do a straight swap with the decat for the cat and I fancy a change anyway so want to make sure if milteks and scorpion cat backs are the same size as the standard vr exhaust before I make a purchase Sent from my iPhone using Tapatalk
