I would keep the cat . I just received notification by mail that medium duty diesel trucks here in Nashville will have to pass emmissions testing . I'm glad I kept the cat and put on Mark's cat-back system . I guess I will have to go to the dealer and get the P-0191 code removed before testing . I have heard that you will not pass if you have any engine codes .

 

Whitesport, and anyone else, do you still have the downpipe and would there be a chance of allowing a wimpy 04 305 to acquire it and utilize it? Let me know the best deal..... Thanks, John

 

I made the mistake for buying the pre bent pipe and spending $90. I did this to a buddies truck and it is the easiest and cheapest. Instead of having some muffler shop charge an arm and a leg for their work do it yourself. Go to you local auto parts store (NAPA is where I went) and get 3 feet of flex pipe and two 4 inch band clamps. Total cost is $35. Cut the muffler out and put in the flex pipe and clamps. You retain the stock location and the sound is not loud but a nice deep groan WOT.

 

jwtuc,

Yep it's hit the big city now on all the light to meduim duty diesels. I wonder if I should start e baying all the old cats I have collected from customers over the years!!!

The info they sent with my renewal was a little vague, you seem to think it's just a sniff test, or what? Have you been thru it yet? Let me know if you would or stop by the office if you want.

Hehehe....you guys should have bought an '03. If it didn't COME with a cat, it doesn't have to have one.
