Help, I ordered catted dp’s thinking they were catless....
So I just received my catted downpipes today but when I placed the order I could’ve sworn I had bought catless. So I checked the order and it does indeed say catted. So now idk if I should return them and get what I wanted or just keep them. What do you guys think? Pros and cons of both?

Also, the dp’s that I got today are Heat Shield - 200cpsi High Flow Cats

1) Well one requires a Tune, the other doesnt..
2) One will prob introduce more "smell" then the other (fumes)

etc and or course all the other normal stuff ith catless dp's

what state you in?
​​​​catted is much closer to being legal at least, i doubt catless is really gonna provide much more power

I asked that question to my engine builder:

"Will catless pipes make a big difference"

"....... well I've never heard of anyone fitting them to go faster"

If you are going to use spacers, why pay the extra for catted downpipes, just go catless and get the spacers with cat material in them to avoid getting a CEL.
