I have the stock Axle-Back on my 2011 mustang GT , Does it require a tuning after installing the AFE Axle-Back to get the 18HP ?

  • The increases of up to 18 RWHP and 15 ft/lb RWTQ were gathered with a Dyno run we would recommend grabbing a tune in order to get the most out of performance from this AFE Axle Back.

Will these be louder than the corsa axle back? And, if I have a KN CIA and a tune, do I need to tune again after install. Thanks

  • This axle-back setup will not be as loud as the Corsa axle-back which is one of the loudest that we offer on the site. As far as tuning goes, since you are only looking at a new axle-back exhaust you will not need to retune your vehicle.

How are these any different than Magnaflow Streets??

  • These will have a slightly different sound than the Magnaflow street item #48052 as both of these muffler chambers have no packing but Magnaflows are perforated differently than aFe's.

    Perfect mufflers

    These sound great. Startup has a nice bark to it but they quiet down pretty quick. Idle and cruising in 6th are as quiet as stock but when you get into it you for sure hear the difference.
