I currently daily a 2012 Supercrew with lts, highflo cats and a Roush catback. For context, I bought the catback before the longtubes and it droned BAD. The longtubes help a bit, but the drone is still quite annoying with the roush muffler. I have looked into getting a corsa Xtreme system, which I have heard have near no drone, but I don’t want to drop 1.5k on a catback. I would rather just swap out the current muffler and slide a new one in its place. Does anyone know the specific part number for the standalone muffler that corsa uses in the Xtreme catback? And if not are there any specific mufflers that measure up to the Xtreme system? Any insight would be appreciated.
