Just got back from the muffler shop. It is actually 2.25" exhaust. Good thing they could make the 2.5" X-Pipe I bought work.

So sorry for the incorrect response. I was going with what Corsa told me when I asked about the their cat-back vs. my stock Summit. I never personally measured the diam. Glad your shop could handle my error for you.

Ya that's what Corsa told me when I had the custom Corsa put on my '14 summit hemi so I fed that to OP but when he posted it was actually 2.25 I busted out my digital caliper and measured mine mid long pipe its definitely 2.25 od....hmmm strange yours is 2.5 supposedly same exhaust, only diff being end suitcase angle and its exit pipe and then bumper tips.

I was a card caring Journeyman Millwright in my day.
I know how to take measurements.
Serrette Calipers
MY exhaust system pipes taken at 3 places is beyond a doubt
2.5 in ---Outside Diameter.
Mandrel bent measuraments
2.498-2.51-2.50
Just not arguable at all for a - these - particular pipes.

Wasn't doubting just stating how strange it is to have 2 diff pipe diams on same year/engine.

Yes it is strange
Things get challenging sometime.
Doubting myself.
All things possible

This part number is
Corsa 14457.
They make several different sets I believe.
Different stages.
I got whatever Auto Anything had,
Silver Tips.
But I think they make a Touring and there are big pipes for the SRT-3inch.

Ya I have basically the exact same just modified with quad tips and custom suitcase exit pipe and hanger ... Corsa designed and installed at their factory, I live 10 miles from it.
