I read your post from 2012 on Roush exhaust. I have a 14 mustang convertible v6 I'm looking at replacing stock exhaust with Roush axle backs. Have you been pleased with Roush and is there a lot of drone while driving on flat highway? I've been doing research and some say there is a lot of drone and others say only going up hill. It sounded like you had convertible so would like your feedback. I'm looking for that deep exhaust sound but don't want a bunch of drone unless I really step on gas.
