Desperately seeking a nice deep tone without drone I started inquiring here and asking others the best muff to replace the stocker to get a little more sound (more power is a bonus). With previous experience working on TBSS, Jeep SRT8, Charger SRT8, Dakota R/T, Mustang 5.0 (2012), and others we all know where catbacks give the best HP they are also an expensive upgrade. I tried the Borla XS, Flowmaster super 40 and super 50, Dynomax VT and Dynomax super turbo. The Super Turbo was my fave. It had the best all around sound without drone. Sound is highly opinionated by all but if you want a great sound muff when you hijack your cats this is an excellent option and easy to do if you find a muff shop that has custom pipe bending available. Looks just like stock and sounds like a V8. The key is getting a 5x8 case muff or smaller with center input and staggered output to line up with the stock outlets. Your installer will hack the square outlets off the stock muffs and weld on the new muffs (AFTER YOU APPROVE THE WAY IT SOUNDS). The entire test process (tack welding the assortment of muffs in place to ride around the block) took about 2 hrs with final installation. I highly recommend ordering a few you want to try from Amazon if your installer doesnt have in stock and try them out. My total investment was $200 with muffs and installation.
Borla XS - higher pitched sound, drone, but sound great at WOT
Dynomax VT - almost identical to super turbo. A little quieter at idle.
Flowmaster super 40 - too loud. drone at idle and WOT. sounded like my mustang
Flowmaster super 50 - not too much drone. sounded good but too much like my mustang.
Dynomax Super Turbo - Deep at idle and amazing and smooth at WOT.
