  3. Do you all recommend the Roush Mustang Axle-Back Exhaust?

    Mustang EcoBoost Discussions
    I recently got a Mustang ecoboost 2018 and wanted to get an exhaust system for it to make it louder. Do you all recommend this one: Roush Mustang Axle-Back Exhaust 421837 (15-19 EcoBoost w/o Active Exhaust) Does it have a lot of drone? If you don't recommend that one, which do you recommend...
  4. New Roush Cat Back Exhaust

    Mustang EcoBoost Discussions
    Does anyone know where I can find a sound clip of the Roush Cat Back exhaust for the ecoboost? I think it just came out. American muscle nor Roush website doesn't have a sound clip. Im trying to compare the sound to the Borla Atak.

  6. Mishimoto vs Roush CAI

    Mustang EcoBoost Performance
    Hey, I'm going to be purchasing a CAI but I'm torn between the two ( mishimoto and roush). Which one should I go for? The mishimoto looks a bit higher quality but the roush looks better under the hood. 2015-2017 Mustang 2.3L ROUSH EcoBoost Cold Air Kit Ford Mustang EcoBoost Performance Air...

  8. Is this tacky re-badging?

    Mustang EcoBoost Appearance
    I'm looking to get rid of the chrome pony on the deck lid, and I originally planned to go with a GT style, EB emblem. I was searching online the other day and came across this Roush faux gas cap deck lid. I like the look but at the same time I'm not trying to badge the car as something that it's...
  9. Roush Cold Air Intake CAI Performance issues

    Mustang EcoBoost Performance
    Total Ecoboost noob here (still have temp plates) but already threw the Roush intake on the car. Great sound while accelerating and release but the sound actually seems to be the intake sucking out power. At 50% throttle it feels fine but mashing it down, even for a few seconds, the car doesn't...

  11. Roush Fascia Grill Change....Thoughts on my idea..

    Mustang EcoBoost Discussions
    So I really like the look of the Roush Fascia, but part of the reason I love my car is the Pony Pack grille. From what I can see the Roush Fascia has lip in the top grille that makes it so that a stock grill would not be able to be put on. But I wonder if I can modify my grille slightly to make...
