Guys.....which do you like the most.

I've listened to a bajillion videos and I just do not know which one I like the most.

Is there an advantage to one over the other?

Prices the same?

How much of the stock exhaust do I get rid of? Mufflers to tailpipe? More?

Sorry, new to this and need advice.

This will be for a new 13' GT

I don't really want the loudest, but I do want the "beefiest"...if that makes sense

 

I have a 2013 GT Premium convertible. The beefiest not the loudest is what I was going for too.
I had the Roush axle-backs put on my stang. I LOVE 'em. They have a nice deep roar. They're nice and loud when I stomp the gas but quiet enough that in my dead-end 25 mph neighborhood I don't get the "older folks" (there's a fine line between me and them) screaming. Also, when I'm on the highway, conversations and music are easily heard.

I wouldn't pay too much attention to the video clips. I think they are limited to your coomputer speakers and none of them are done any justice. I spent a couple hours listening to the video clips, I made my husband listen to them and my stepdaughters. We all agree they all sound alike on the computer.
I do have to say as a side note, my son-in-law, who has rebuilt a few mustangs, prefers the sound Borlas and was a little disappointed I went with Roush.

 

Tell your son-in-law he needs to have his ears checked. For the S197 cars, Roush uses Borla mufflers (just rebranded). LOL
