        sounds good, looks good

        You might be on the fence about whether to buy this version of the race version. I bought the street because I did not want to hear a loud drone in the cabin during everyday driving when you're staying around 2k RPM most of the time and this achieves that. It still has a nice loud sound when you get on it but won't annoy you if you just want to chill with the windows up. Easy enough install but it does take some work to get everything to line up properly.

        SO happy with this exhaust

        Went with the street version rather than the race. I'm not looking to be obnoxious to my neighbors. Those same neighbors, immediately noticed the difference and were as impressed as I! Installation was very easy, made easier by the fact I found a shop that let me use their lift. Everything fit well. I had the stock system out and the new system in place in less than 30 minutes. Looks great, and the sound matches the performance. Totally worth it.

        5 2016 EcoBoost - Richiedodges Installation Time: Less than 1 Hour

        Nice rumble, next to no idle drone

        Sounds great. Gives a nice hum when you accelerate but no annoying drone for highway drives. Cold start sounds nice and after a few minutes the drone is almost silent. Nice for the early mornings. Only problem with the install was the connection point of the exhaust and the cat. The pipes were the same size. They neglect to give you any connections and tell you to reuse the factory clamp when you remove the stock exhaust. This can’t be done. Connecting two pipes of the same size with nothing connecting could cause a leak. Was forced to add a small piece of pipe and weld it all together. No going back now !

        Had some issues with my order but they were resolved quick. This exhaust is perfect for someone who daily drives and does not want much to any drone. Very low and deep at ideal. Perfectly balanced exhaust in my opinion.

        ITS SO GOOD

        It’s very loud and performs very well. It caused a more aggressive take-off for my car, and has a nice crackle to it during the cold months. It’s hard to believe it’s just a 4-cylinder with this exhaust installed!

      I just installed the MBRP Black Series Exhausts on my Eco Boost last week. They sound incredible, now I want to install a CAI would anyone recommend the Roush CAI for this car

      • The Roush cold air intake would be a great pairing for your Ecoboost! You can find that cold air intake here:

      How loud is this exhaust inside the car? More specifically I'm worried about drone when I'm in 6th gear doing 70 on the highway. Thanks!

      • This MBRP Street cat-back is one will not be as loud as some of the other cat-back exhaust options that we offer. With that being said, there has been very minimal droning if any at all. Please check out some customer reviews to see what others who have purchased this exhaust are saying about it!
