Default xr1 borlamouth question

Hey ive searched and am wondering where you find the right size borla xr1 to replace the loudmouth resonator? All i see is 3 in 3 out,, and my resonator on LM1 measures 2.75, where are you finding the direct fit one? swapping to headers and ory's so the loudmouth is gonna be too much. is this borlamouth going to quiet me down a bit? live in apts riht now , thinking of chambered catbackbut this sounds the easiest and been told its alot better.

I'm in the middle of swapping out my LM2 muffler for a XR1 right now. The 3 in/3 out ends are slightly larger than 3 ", they are designed to slp over 3" pipe. It fits perfectly over the inermediate pipe, but the pipes are the same diameter on outlet vs where it goes over the axle. I'm taking mine to a muffler shop to modify the end a little so they slip together.

yeah, well my prob is when I measure the pipe going into the LM1 it measures 2.75 inches, not 3. but SLP says its intermediary pipe is 3" .... when i measure where the ypipe conects it measures 2.75... on a SSA long tube header set.... im trying to figure out how they can claim 3" when it measures 2.75 and if a 3" borlamouth will fit into this picture seeing as I see nothign thats 3". were loudmouths EVER 2.75? Its incredibly confusing because my tape measurer says 2.75 even though all documents say 3.... anyone else ever have this prob??
