Does anyone know the diameter of the MRT h-pipe with cats?

[HPLouis]

Hi,
I'm looking at replacing the mid pipe on this car with a catted h-pipe (I want to stay emissions legal) and I read that the stock pipe is 2.75 in diameter. I also read somewhere that the MRT pipe is actually smaller in diameter because it's made for the 11-14 Shelby's and the 11's-12's had a smaller pipe.

Can anyone confirm that the MRT is actually smaller than stock? If that's true, then I'll just stick with stock.

Thanks

Forget it, found the answer right on their website: Shop MRT | 2011 - 2014 Mustang GT500 MRT MaxFlow H-Pipe : Race Cats #93P602 Sport Touring Exhaust

Under feel the performance, it asks, what is the tube diameter and the answer is, "Large 2.5" tube is used for reduced exhaust flow restrictions".

It's smaller than a stock 2013-2014 Shelby's 2.75"

Good that you posted the answer you found. Hopefully it will help others going forward who might have the same question.

Thanks. It would have been an expensive mistake if I got it. I bought a 3” from Stainless Works instead

I think the opening on the exhaust manifolds is also 2.5"
True 2.75" pipe does have more room for expansion.

The stock mid pipe is 2.75" on 11-14 GT500s BTW and 07-10 is 2.5"
