Dan,
I installed the Roush H pipe with the Ford Performace Borla Sport mufflers. Closest to the "old school" sound I could get. Can be quiet if you dog it around town... but if you punch it... it screams. I watched a thousand videos prior to making my decision and all I can say is they are...
Benny,
I signed up just to reach out to you. I just purchased a 2015 GT and looking to wake up the exhaust!
After a couple hundred videos I think I settled up on Ford performance Sport Mufflers and an H pipe.
Can you help? Thanks
