F150 ECOBOOST Full Exhaust Install | MBRP SPD AMS 

Vaguely sounds like a Cummins😂

I feel ya on the rust. The bed sides have foam along wheel arch and they rust from inside out. My rockers are gone too. I have a Gibson stainless steel cat back exhaust. Love it

I have a cat-back from MBRP for 3+ years & I still haven't put it on yet. Ha.
