Im looking to get a new axle back for my 2007 mustang GT. I dont want anything too noisy to where I'm hearing nothing but my engine at highway speeds. I was particularly looking at the S-type (Stinger) and want to know how loud it is. Also want to know the difference between the 3 as in performance gains and sound produced and also the level of sound. so far i have a set of bbk long tube headers, bbk shorty catted x pipe to my exhaust. which one do you guys prefer with the x pipe and long tubes? also, what about the bassani axle backs? how are those? which ones do you guys prefer between borla and bassani? thanks for any input i greatly appreciate it.
