Has anyone had a custom 3” exhaust made for their Maverick? Looking into getting one made and curious to see what others have done.

I am curious as to what you would hope to gain with a 3" exhaust???

Although my 3” is aftermarket, you should expect deeper tone, more drone, and less clearance between pipe & heat shielding.

Also, since the Maverick exhaust is routed over the RDU - you end up with a bit less ground clearance.

Could not notice any +/- to performance or mpg’s because I installed during break in period

I inquired about this to MRT when buying my catback from them. I actually just called and spoke with Dave to reiterate what he said so I’m as accurate as possible.
So basically there isn’t enough flow from a four cylinder engine to warrant a 3” exhaust. It’s a “bigger is always better” mindset/mentality but the goal with exhaust is to increase flow and with too large a diameter exhaust rather than exit it would create tumble where the exhaust is bouncing all around rather than exiting and create a situation where instead of reducing back pressure it could actually create some back pressure negating the goal of increasing performance.
I know some owners are already running a 3” setup and may argue/differ that opinion and that’s fine, I won’t go back and forth, but I’ve never had a company sway me from something unless they didn’t want to risk their reputation of performance by doing something that could end up being more detrimental than helpful.
I did let him know I have installed the Livernois tune and I’m pushing more power and boost and that I’ll also be adding my CVF downpipe, that’s when he said it’s not about power, it’s about VOLUME.
He said the same was true for intercoolers, that bigger isn’t always better and the same situation can happen where rather than increasing flow there isn’t enough volume and the flow bounces around rather than straight through, which hits me as I type this and I’ll probably opt to spend the extra few hundred on MISHIMOTO Ford performance intercooler than the other less expensive intercoolers available just to be on the safe side as the side tanks on the MISHIMOTO are noticeably smaller than the other aftermarket brands.
Again I’m sure some will say that’s BS because their truck or a civic or a Focus RS or whatever 4banger runs a 3” “just fine” and again I’m not here to argue, I’ve said my piece and that’s all. Just wanted to add to the DISCUSSION.
I’ll take the better performance option for less money all day!
Also note the sport exhaust Ford performance offers is 2.5” diameter. I would think if there were actual gains to be made they would have went that route.
