I have the truck listed above, i’m looking into replacing my exhaust. However, the ones i’m looking at are for the 3.5 ecoboost and 5.0. I’m wondering if an exhaust for a 3.5 or 5.0 will fit properly? I’ve read both yes and no answers.

Hello, I'm Danny.

Just a few questions first. Are you looking for an exhaust system from another truck to put on or are you having a new exhaust system installed? I can find out but need to know what truck model like Lariat, XLT, FX2, etc, and what is the bed length? 67.0, 78.8, or 97.4? Let me know and we'll go from there. Hope this helps and thanks for using 2CarPros.

Thank you sir I appreciate it... I’m going to have whatever I decide on delivered to my farm and I can weld it up from there. I need something to also replace my catalytic converters. Do you have any recommendations on a catless down pipe or catless y pipes?
