These Super 40's really woke the car up. Very noticeable gain in acceleration. I also had my muffler shop install an X-Pipe and wow did this pairing wake this GTO up. Spent half of what a cat back system would of cost.

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.
