@pitzer3 is it still street legal if you do so? like will it pass inspection?
-
yes you can remove them , but keep in mind you are breaking a federal law by doing so, and runnng the risk of not passing smog.

i have an 07 titan, if i remove the secondary cats will the check engine light come on? will i lose or gain horsepower or will it just be louder?
-
when you say "second set" do you mean the two closer to the back of the truck? and the Check Engine light will not come on?

I have an 07 also. i didnt remove the secondary cats but i did take them off and gut them. I am currently running open but i am either going with glass packs or 40's. There is no h pipe. The stock exhaust on an 07 runs true to the dual in single out muffler. the h pipe is custom. i went with an x pipe. The 05 isint true dual all the way back. And if it is a 2wd then you will have resonators not secondary cats.

These trucks have 4 catalytic converters. You can remove the second set because they are behind the rear o2 sensors. Helps flow and makes it louder.
