Swapping mufflers on 2014

Has anyone tried to swap the Roush axlebacks for a different setup? I'm talking keep the square tips, but ditch the mufflers themselves for something like a Flowmaster. I have put an O/R X pipe on my car and it is obnoxious loud. And not in a good way. I realize this will require the help of a good exhaust shop. My concern is any length differences, and whether the tips will fit right or stick out 4" and look goofy. I would like to keep the tips as clamp on type, so cutting them shorter and welding them to the new muffler would be a last resort.

I don't know why it keeps putting tmuffleres in my post. I promise I didn't type that, and if I go to edit, it doesn't even show it's there.

Yes it will work. But I would stay away from flowmaster, they sound like complete crap without cats on the coyote.

Let me know I am having the same problem my 2012 had Borla after trying Roush and Magnaflow
Borla was the best.

When it comes to exhaust sound, personal opinion has to be taken into account. What I like and what you like may be two different things. And that is ok. This is why there are umpteen companies building mufflers. I had several people tell me they loved the Roush axle backs with the O/R x pipe, but I didn't. I like Flowmasters. Even on the Coyote motor. There again, personal opinion.


Well, I got them on. I own a machine shop, so I can do pretty much anything with metal, and spent about 3 hours measuring, cutting, fitting, cutting, grinding, fitting and fabbing before the 44s were ready to take to the exhaust shop. I was allowed to help during install, as to make sure everything is how it should be. New hangers were welded on and aligned with the factory hardware. I couldn't be happier with the results. Looks like factory Roush, but a completely different sound. It is still loud, and drones a little more inside the car. But instead of a high pitched raspy sound, it has a deep, rumble, hollow tone. I love it.


So yes, it can be done. Requires a bit of extra work, but it can be done.

Good report Blackpearl. I agree that everyone has their own personal opinion. I put flowmasters on my 2012 Boss 302 and loved them. I do like the stock Roush set up on my RS3. It has a nice "bark" to it.

I recently did the same swap... I had the roush axle back on my 2013 Roush Stage 3. I absolutely loved the sound but I decided to go to an off road X pipe and it was way too loud so I switched to the GT500 axleback with the off road X with stock resonators and I couldn't be happier. I was able to keep my roush square tips and everything looks and sounds great. Hope this helps
