    I read all the reviews and watched the demo video and it was everything I expected! I love the sound of my 2020 EcoBoost now! The factory exhaust was lacking any sound but this is just right, I didn’t want an obnoxiously loud exhaust and this was perfect! Thank you!

  2. Greatnoise

    It makes an incredible sound. I love it. It was easy to install aparently.

  3. Kyle15

    Super easy install. Instructions were very clear and easy to understand. Took me and a buddy 45 minutes total to install.

  4. Photonarbiter

    This thing has transformed the car. I’ve had it on for a few months now and it really does feel like the best of both worlds. I’ve had the car mistaken for a V8 by people in parking lots and it’s surprising. While it doesn’t really sound like a V8 the deep tone is similar and makes the car sound much more powerful. While cruising around on the street or highway you can control the sound by how hard you press the throttle. If you’re gentle it’s as silent as the stock exhaust, if you’re on it the thing really sings.

    The welds are good, no leaks, and it sounds amazing. The fitment was a bit off however. The shop I took it to for installation had to make some adjustments to get it to fit right, so you definitely get what you pay for. Overall, I would recommend this to anyone looking to make their car sound better without breaking the bank.

  6. Archiavious

    If you want an annoyingly loud exhaust, this isn’t the one for you. MBRP balances it perfectly with this exhaust through a refined deep note throughout the rpm range. Even burbles and pops sometimes when it climbs down the rpm range. Definitely a good investment if you want a quality sounding ecoboost mustang. Worth the money

  7. Justin Smith

    I bought this simply for the piping. I expected it to be a trash system and not fit at all from other reviews. I bolted the two pieces together first. Then bolted to the cat pipe. After bolting tight I then put it in the hangers. Everything fit perfectly and sealed good. Even lined up in the bumper properly. The sound was a million times better than I expected. I will probably leave this muffler on until I go turbo.

  8. Deejfriend

    I first installed this cat back on my 2018 premium convertible. It sounds amazing with natural moderate exhaust bass. I have now included a mishimoto catted down pipe and wow, I still get that moderate volume but it is much richer and satisfying to the ears. No issue with neighbors or going top down with fatback or extra down pipe installed.
