The 4" tips are finished with a new chrome flashing process that is resistant to discoloration due to exhaust heat.

    Can the stock exhaust go back on after having this on?

    mustafa

    • Since this exhaust is a clamp on, you will be able to re-install the stock exhaust at a later point in time.

    Hi! I just ordered this exhaust along with the Flowmaster Scavenger Series Cut and Clamp Resonator Delete Y-Pipe (Item 389694) for my 2016 Ecoboost, and I read that they will fit fine together but I was just making sure before I tried to get them installed. Thanks!

      This exhaust makes my V6 sound like a muscle car. I get a lot of compliments because of it. Nice sound, without the annoying drowning.

      So Good You'll Forget You Have A V6

      I've spent a lot of time researching which exhaust fit the bill and when I pulled the trigger on this one, I had absolutely no regrets. It sounds AMAZING. It's quiet when you expect it to be, but loud in all the right areas when you increase the throttle.

      significantly more throaty sound

      Great exhaust but if you really want to hear that roar you need to get rid of the stock pipes and get an x-pipe to unleash the raw sound. sounds even better with this exhaust.

      videos are deceiving

      the sound is amazing, I didn't think it would have a good sound because the videos on this cat back sound "ricey" but in person its a low deep growl and it sounds perfect around 3,00 rpms. would recommend to someone!

      Drones when installed on my V6 w/Auto. Trans.

      Before buying this Roush $547.00 exhaust system, I read several of these reviews. Most said they didn't experience any drone at highway speeds. From this I would assume No Drone. I have an automatic trans. and there IS drone when in 6th gear, regardless of the speed. In otherwards, it drones at Any speed when in top gear, even at 40 MPH! My solution is to shift manually in city driving. I do like the sound when accelerating! I'm very pleased with the sound!

      Roush Axle-back Exhaust

      What to expect from Roush? Excellent performance and it is just what I wanted. The loudness is there when you want it but also calm when you’re cruising around.

      Worth the Price

      When I bought this axle-back, I was looking for an exhaust that was going to add an impressive deeper "roar" that was more respectful over something loud and flamboyant. I'm a daily commuter (50 miles daily), driving almost always on the highway. This exhaust has a small drone initially, but you quickly get used to it. Around 2 RPM , you'll definitely hear it in the acceleration, but it isn't annoying or sounds cheap. Sounds like a high performing sports car. Remote-Start sounds 10x better. this was definitely a great buy for me. Friend of mine is an engineer and put this on for me in about 90 minutes.

      Review from Roush Axle-Back Exhaust (15-18 EcoBoost)

      Wonderful note, not as loud as a Roush

      I've had a GT with Roush axlebacks, these axlebacks had kind of a similar note, which I like. However, Roush axlebacks alone won't give you the desired loudness since its a 4-cylinder car. I am getting an off-road downpipes and a resonator delete and will see how the sound will be.

      Very good Exhaust

      I've had this exhaust on my V6 automatic for about 4 months (shop install for $120) now so i think its enough to see how I feel about it. It sounds really good at low RPMs. Nice, deep tone at a good volume. It's not obnoxiously loud, you probably wont be awakening any neighbors. My car is stock besides this exhaust so I plan on adding more mods to see how loud i can make it. I really like the exhaust at lower RPM but at higher RPMs it starts to sound lawnmower-ish to me. I'm hoping other mods will help with that. As for drone, there is the smallest amount of drone lower in the low RPMs at higher gears, this drone is so small i cant see it bothering anyone. All in all i do really like the exhaust hence me giving it 5 stars. Very good for a daily driver.
