I'm looking to pull the trigger either today or tomorrow on a set of CATTED Downpipes for my 2013 SHO, I see livernois has them in stock ready to go.... In your Opinion, which will be the better CATTED downpipes for my car? I want the catted. because I want to pass inspection. Thanks in advance guy's. I will be installing them this Friday ( have my buddy's lift to the day) along with my new Lowering springs. Rich
