Very happy with BBK Varitune mufflers!
I had my initial review deleted because after about a 2 week break in period I have been much more impressed with these mufflers. At first they didn't seem loud enough but the volume and tone improved a bit as they broke in. The mufflers are about as loud as stock when the valves are closed; with them open, they are a little louder than the Magnaflow Street mufflers I previously had. I do a lot of highway driving and wanted a system that wouldn't have annoying drone, so I'll mention that there is a light drone around 2k rpm (valves open), but it isn't loud enough to be a bother. The exhaust sounds great when you get on it, but I do wish it was a little louder still with the valves open. Every couple weeks, I close the valves for a few days and then when I open them back up its like having new mufflers again. I would definitely recommend these for anyone who was to give their Mustang a great sound without being obnoxiously loud. These may be the perfect daily driver exhaust.
