I think part of my heat issue is the cats are 20 years old, and are starting their decline to fail. I want to pull the cat after echeck and put in a resonated race pipe from corksport. Also, both my mufflers are rotted out from age, so they need replaced. For the same money, i can get the single cat back from corksport and get some flow, so that's the plan. Plus then she will shoot flames naturally.
