All the guys here won’t let you Fu$k up again.
Here is what you do. Make sure you can verify that the Dp’s you have are not catless. (I know I know) then from there. determine if you want to go full catless or if you need to for emissions. Some guys in your area are already catless and are able to pass emissions.
From there if your going full catless you have options and if you want and need to keep the cats go piggies.
Also AR has a large resource of members that might be able to help you sell and swap the Dp’s. So if you feel comfortable post your nearest location. This might help getting you to a different shop that can help remove the Dp’s and possibly source you piggies.
