'' Car was 100% stock, with 30 miles on it, Gas in the tank was original from Ford.

No tune was made, zero modifications aside from a cat back exhaust. No headers, OEM cats remained.

Gear dynoed in was 5th with 1:1 drive ratio.

Dyno used was a dynojet.

Multiple factors apply to the restriction, the piping size off the manifolds and for the whole exhaust is actually smaller than 2014, the cars have a super restrictive mufflers that are likely in place to keep it quiet for global standards, as well as the 3 muffler/resonator set up as opposed to the 2 muffler set up we are used to seeing on Mustangs.

I attribute that to Ford really stepping it up for global comforts.

Just a quote, I do not believe it. Seems like a big stretch for a catback/xpipe WITH CATS. 14' 5.0 XPIPE gains where awesome because of the cats removal or high flow cats replacing stock ones. Like when you replace your stock cats on a LS3..hello 15-20rwhp.
