yea, once i get enough funds saved up i think im gonna hacksaw the entire muffler off infront of cat, weld a straight pipe in through the cat, weld cat around pipe and eliminate u-bend and all. I'd weld the cat back around it so it will pass inspection ;]. Then a PCM if i can find a dealer who will CASE learn it :/.. It actually runs alot better and gas mileage isn't bad. filled up and set trip, gone 125 miles on a 1/4 tank of gas. We have a lot of hills here in WV and it wasn't all highway. It sure is better than when the converter was all messed up lol 150 miles to the tank >.>
