I'm Awesome
I've owned 3 of these truck now. The '92 & '93 had larger exhaust pipes coming off the manifold into a large cat. Both were 2 wheel drive. One was a 4.3 and the other a 5.7. My '98 4 wheel drive had smaller exhaust pipes coming off the manifold into two small cats and then continues to be dual all the way to the muffler. It's a 5.7 as well. Just wondering what models/years/options had the dual cat set up. Is the dual set up better?
