Selling a MRT Interceptor cat back exhaust for a 15-17 Mustang GT. This is a full 3" system. Definitely louder than stock, but not obnoxious. Pretty much zero drone on the highway. The system is in great condition and has less than 9000 miles on it. Local sale only (I'm in NJ - Essex County) - will meet if you're too far to pick up. Asking $800 obo (price is about $1300 new). Text me at 862-201-3477 if interested. Thanks.
