Howdy all! My titan had modified exhaust on it when I bought it and I'm not sure which portions are stock and which aren't. Trying to modify it and need to know what I'm starting with.

Thanks!!!!

Thanks guys. Sadly I'm a little more confused. Are the cats only in the b pipes and the headers? And removing the cats in the b pipes is ok?

yes you have a set of cats that attach to the rear of your stock manifold and a secondary set at the end of the b pipes. A lot of guys here delete their secondary cats including myself. it all depends on if you have state emissions if you will pass or not, luckily for me.... I don't. I also have never had a CEL with my setup.
