This new exhaust is from the MRT company, they do performance work for Ford and are famous for their Mustang work................I spoke with them months ago during development and told them "NO drone on the highway!!!" They said that was one of their main concerns. Looks like the muffler is located just in front of the axle, that will help keep the noise down....

That sounds ok...I think Allieds have a deepertone, more full (but not obnoxious) rumble than the MRT (unless you are looking for a more subdude sound). Allied is also a fraction of the price in either gal or SS. Myself & family have been using them personally since the 60's- and the flow is evey bit of the race spec mufflers.

The MRT is very pretty!!!

 

That MRT sounded pretty good on the ecoboost....
