Bone stock 6m 2011 5.0, looking for a cat-back that will perform while staying as close to quite as the stock exhaust. Will consider all options, JBA, Flows, Pypes, GT 500 anyone who can help I appreciate it thanxs guys and Be safe out there, hell of a car to drive slow.
I had a Magnaflow Street catback with after cat x-pipe for a little over a year. I eventually sold it because it was too quiet and tame. Keeping the stock cats is key to a quiet exhaust. As soon as they are gone the volume goes way up.

mbreinin recently did a review on the JBA axlebacks. I wouldn't get the JBA catback. Save yourself a few bucks and get the axleback kit then get your resonators cut out.

Gt 500 was most likely wat I was going to go with, but if I can stay fairly quite with a Bassani or Jba maybe one of those. If a tune makes the gas mileage better I need to get that done ASAP, intake and tune, be my Christmas present to myself. Thanx everyone for your responses- keep them coming I like this site and check out my other threads, I have some other questions, just got my '11 5.0.

Just kind of throwing this out there.
Why buy a Mustang GT and worry about gas mileage?
If you are getting good gas mileage then you are driving it wrong.

Axle backs will not gain any performance. If you want quiet, keep the stockers.
Frankly, neither will most catbacks. Not without headers or an off road mid pipe anyway. Then the situation just starts to get a little heavy handed. Borla and Magnaflow, ok, 10'ish RWHP supposedly. Ditching those stupid resonators helps a bit though since they neck down quite tightly. Borla's catbacks are only 2.75" piping, just like the stock system (sans the resonators), granted the Borla system is much smoother in the bends and doesn't have as many of them.

I don't believe gas mileage is a worry here. Wasn't a consideration for me. However, I am happy to see a calculator verified improvement in my mileage with a tune. Good gas mileage relative to performance isn't something you see often discussed and something we take advantage of. Our mustangs when driven normally are really efficient. Much more so than our German friends (at least according to my m5 and e63 friends).
I have Corsa extremes. Love them. Quiet at idle, just a little louder than stock. At cruise speeds around city and on highway they are
louder than stock with a nice muscle car rumble not bothesome in any way. at wide open throttle words cannot describe it. They are loud and aggressive. You only know they are really there when you really get on it. And there is absolutely no drone at any speed. I have tried them with and without resonators. A little louder without them at lower speeds but still very tolerable. At WOT without resonators all the sound goes out the back but Im told they are loud.
I also love the unique tips on the Corsa mufflers . Worth the money IMO.
And no, I dont work for or have any affiliation with Corsa.Just a satisfied customer.
