Hello all. I have a 2017 GT 6 speed. I would like to perk it up a little. I installed a K&N Typhoon intake the other day and love it. I am interested in opinions on cat back streetable exhaust systems. I like SCT tuning as I have used them on my F-250. I am not new to performance, just Mustang performance. I have been driving a blown alcohol 23T for the last 15 years and had to stop due to back surgery. So, this will be my new hobby. Advice on performance add-ons will be appreciated.
