I have an 06 gt with steeda axlebacks. I eventually added on an o/r h pipe but even without it was a considerable difference. I can get you a clip somehow if you'd like. (with the stock h pipe and without)
Hey all!
I signed up but never formally introduced myself.
My name is Angela, just purchased my 2nd mustang in February. Previously had an 04 DSG (v6).. I knew I would upgrade eventually and finally was able to.
Happy to be here!
