Howdy friends... a little while back I put a set of Borla S-Type axle-back mufflers on my 2008 Bullitt (new, these are > $600). Part number on this set is 11750... these fit 2005-2010 Mustang GTs. I drove less than 3K miles but decided to go back to my original 2008 Bullitt mufflers. These Borlas not overly loud and give a nice burble and tone, but I'm trying to keep the wife happy. These are in excellent shape... reach out for details. I'm in Austin, TX and looking to connect with someone who can do a local pick-up (I don't want to fuss with shipping). This is a SUPER deal on a set of high quality axle-backs that are like new. Check the description on Borla or on Amazon.com... these are high quality steel with polished tips. The mounting clamps come with the mufflers... I can print out the instructions if you need them, but it's as simple as a socket and a ratchet (you'll re-use your existing muffler hangers)...
