Does anyone know if the SLP Loud Mouth exhaust is legal? Meaning will I pass my emissions test when I go? Thanks!

You won't fail emmissions unless you remove the cats. (Or if you switch to different cats possibly.)

Yea, I'm sure. You won't fail emissions by putting a cat-back on.

A lot of it depends on how big an a$$ you make of yourself in front of the right/wrong crowd. Those systems are loud alone as cat-backs and are seriously satanic when coupled with off-road mid pipes.

Proceed with caution.
