My Tru Duals Questions.
You are supposed to have cats but again most do not give a ****.
If you live in an area that does emissions testing, you want to keep the cats so you can pass, though do some searches I am not sure if you can trick the system or not. If you do not have emissions testing, you are good to go, no worries.
The TSP is good stuff, I have the headers and X pipe.
