Exhaust

[Nakita23]

I have an '11 XLT that I'm considering putting just a flowmaster muffler on. I have measured as best I could (with string measure around then divide that length by 3.14) What I came up with was 2.71" inlet & 2.6" on the exit.
Can anyone advise as to what size I need to look at buying. I'm also looking to get the 50 series as I don't want it loud just a nice rumble.

I used a 3" in / 3" out stainless muffler from summit racing.

Course, I am a welder so I made rings to adapt/ welded gaps.

I had local muff shop put a 50 Flowmaster on my 2010. Cost $160 parts and labor sounds just right.
