Hey everyone! I live in Colorado and was thinking about doing a muffler delete on my 06 5.9. Could not find any emissions laws to see if I would fail emissions because of visual inspection. Thanks!
wouldn't the 06 have the same set up as the 04.5 early 07..? with the football cat, post downpipe? there's nothing inside the factory downpipe except soot.
Ya I was going to keep my cats on and just remove muffler^^^ This is correct.
Jacobstrom, if your catalytic converter is gone, you won't pass a visual emissions test.
Deleting the muffler won't affect an emissions test but the truck will be loud and they may ding you on that.
You can go with a less restrictive muffler. No muffler's going to be loud and negatively yours and other's hearing. Take it from an old coot,protect your hearing. It's a cumulative loss starting from adolescence. Loud's obnoxious not power enhancing.Ya I was going to keep my cats on and just remove muffler
