How can i eliminate the cats with out throwin a cell light? i cut off the muffler and dumped the exhaust under the truck for now... it sounds good buts its not as loud as i want it to be. How could i make it louder? any ideas would be helpful. im finally home and want to work on my truck this was one of the first project.

 

welcome home,you can eliminate the two rear cats with no c.e.l. My friend got rid of all four of his cats and erased the c.e.l with his programmer and he has put 100,000 hard miles on it like that with no problems.I just deleted my rear ones and it made it way louder.

 

Im wondering this too. A buddy of mine will be taking mine off soon and he said it ill trip a cel even though the O2s are on the outside of the cat on each side, on the pipe. Didnt make sense to me.

 

A buddy of mine removed the o2 sensers and installed them up closer on the heads (drill and tap). Said it didnt trip his CEL as it was a heat sensitive sensor and that was why they were in the cat. Never tripped his CEL.

 

ive heard from a few people u can cut the back two and a code wont come up. i just ran 2 inch pipe after the cats true duals and 45 out the back

 

I've heard all different stories on it haha. I've got many friends that ran straights or cut off the 2 and had no problem, others that did. There's 2 different set ups on those sensors, either right after the cat, or in the bigger one, like mine is, when their in the cat, you gotta do the whole drill a new hole and put it back in as someone else mentioned, and if you do it right, your good, but the other setup, where its after the cat, just in the pipe, is super easy, and shouldn't throw a code
