Looks like a 50 series muffler, its more cheaper to have a muffler shop weld in a new muffler and new pipes, i have a super44 series, but i also have 3 inch pipes, its louder then the magnaflow catback, i have a v6. Do you like loud? I think super 44 or 40 series is good, maybe u can try the 10series if u want loud, i had a cherrybomb vortex b4 and this is better sounding.
