Without having to.... What? I don't know if there's more to that, if so then the app doesn't show it. Are you wanting to put an aftermarket mid-pipe with high flow cats in? If so then they come with 2 cats instead of 4, they will work just fine but you may fail emissions since you have 2 instead of 4 cats (depends on your local emissions laws)
Yes aftermarket cats with x pipe, the local muffler shop told me to make sure that I get 4.6 ones that replace my stock ones because the labor would be high?, so which ones would you recommend for me to get?
Are they cutting and welding on your current mid-pipe? I would just buy a nice Bassani or Magnaflow catted X-pipe and have them install it. As for the cats themselves Magnaflow and Bassani both sell them. Is there anything wrong with your current cats?
I personally don't think so because I liked the change in tone I got with changing to my O/R X. But that's all personal preference
