Flowmaster Outlaws vs Roush

I know there is a lot of discussion about the best axel backs for the 2010 on GTs

So I just wanted to share my experience with these two axle backs. I bought the Outlaws for my 2011 GT with stock exhaust, after doing a lot of research and watching youtube videos. They sound incredible but the drone at 2000rpm (65mph with my 3:55 gears) was just too much for me with the amount of freeway cruising I do.

So after a couple of weeks I switched to a set of Roush axle backs which have zero drone but really bark at WOT. Best of both worlds IMO.

If you are considering either of these the Outlaws are louder and deeper than the Roush's but you will get drone with the Outlaws.

So I have a set of nearly new Outlaws for sale! Message me for info.

Couldn't agree more. Good thing I do a lot of town driving. Outlaws are amazing for my daily commutes and sound sweet bouncing off buildings. However, if you are a highway cruiser I wouldn't buy Outlaws. They are very loud in car at 65MPH as OP stated.
