Looking for quieter mufflers for a 2011 Mustang 5.0

Does anyone know of a good pair of mufflers that will make my 2011 Mustang 5.0 quieter than stock? Also, what size should I get? Thanks!

Quieter than stock? That’s kind of unusual.

:slightly_smiling_face: It’s badged as a 3.7, so I need it to be quieter. Please help!

There’s nothing in an axle-back setup that’ll make it much quieter. You might try adding additional mufflers where the resonators are, but it won’t be easy to get the effect you’re after.

Quieter than stock? That’s almost unheard of. Factory is already very quiet, to the point it doesn’t even do the Mustang justice. You won’t find anything quieter than stock.

I thought people sometimes modified hot rods to make them ‘sleepers’? Isn’t that when a plain-looking car has high performance but doesn’t give it away? I’m new to this and appreciate the help. Thank you!
