wasn't really sure how they would sound with a 3.8L but I guess it is what it is its not some monster v8.But yes I Really do enjoy the deep sound, Ive ALWAYS loved the sound of FLOWMASTER.

Quiet Power

Reviewed By Carroll J (Palm Springs, FL) Reviewed for a 2016 Ford F-150 —5/14/2017 6:00 PM

I have a MBRP 4 inch system on my 2016 Ford F150 3.5 ecoboost, System gives great power but is loud as heck. When the original MBRP Muffler split at the seams I decided to give this a try. It's perfect. No raspy ricer whine or drone, It's deep and throaty, and not loud. Doesn't sound like a V8 obviously, but doesn't sound like Ricer Crap either.
