CO emission testing and cam swap Anyone here live in An emission testing county in Colorado?
Car won't pass in its current condition ( long tubes and 3in ofy). I'm looking at doing a 228r cam swap and 5.3 heads, along with new tsp long tubes and the catted 3in ypipe. Any have something similar tested? How "good" are the tsp cats? I know the 228r is a "smaller" cam, but would it be to much exhaust to pass a sniff test?
