SLP muffler swap?

[redx2c]

I got a IRS SLP LM1 catback and want to swap out the mufflers?

Does any one know what muffler will swap right in its place?

looking to quiet in down a little bit

Magnaflow will fit into the piping and loudmouth11 will also.. There may be others but I had these in place of the loudmouth1s...
