Anyone know of a good high flow cat for the 05's since you HAVE to have one? Larry, if you sell one, PM me the price. or a delete pipe.

wow, guess they only make them for gassers.

I have the highest flowing cat around - it's my own design.......

Your truck already has a high flow cat on it. As a matter of fact your injectors have a third pulse that helps increase temps in the cat to keep it clean.

Removing your cat will do little except to violate current EPA regulations. You have to be pushing some pretty high HP numbers before it becomes an issue. I can get you a delete pipe but I do not recommend it.

My only problem is that there is something weird with the factory cat. it has a strange down slope to the tube as it comes out and it causes a bad connection between the new pipes and the old pipes. I clamped it realy good but on pumps it forces itself out. I may have to just hit one of the welding shops and get that taken care of.
