Exhaust is mostly personal taste and how much you want to spend. I now have 18" resonator with two turbo mufflers all new 2.25 pipe from the flange back, love the way it sounds and the drone is not bad, but I like drone (used to have a Mustang lol). My entire new exhaust was a total of $328 fully welded.
With that being said, $74 Borla muffler seems like a good price, not sure though.
