for a few weeks it would be factory cat but I would end up getting a high flow cat prolly a dynomax
2009 Ford Mustang V6
Definetly get a hi-flow cat w/ at least an 18" resonator behind it, otherwise ur car's gunna sound like a steroid ridden duck fartin into a folger's can. Or like a honduh w/ a muffler
Other thenthat, it looks like a nice system!
Failure is not failure if you learn from it
