Ford, 2011 - 2016, 6.2L, Stainless - MPI Exhaust Cat-Back Dual Stainless Kits

I definitely do not recommend this exhaust system from MPI. It made absolutely no difference in fuel consumption, and the issue is not with my vehicle — the car is in perfect working condition. There was no improvement in performance or efficiency whatsoever. On top of that, in less than a year after purchasing this exhaust system — which was advertised as stainless steel — it is now completely rusted. It looks like it has been in use for over 10 years. Every part of the exhaust is heavily rusted, and it’s starting to affect the overall condition of my vehicle. This is completely unacceptable. I strongly do not recommend purchasing this product.
