Has anybody found a SS free flow muffler to fit the 2k2 3.5 without making any mods?

You'll have to go to your local shop and have them take a look. I think everyone else here has replaced CAT back.

They'll be universal mufflers, since there aren't any made specifically for the Altima yet.

Needs to be smaller than the right muffler to fit both sides.
