I have a custom dp and HF cat setup. The cat is made from mild steel i think, but the downpipe is made from stainless. I think they need to be used in conjuction, but I'm not 100% sure. I tried to fit it up to my car but the HF cat didn't fit with my setup. I know this combo does fit if used in conjuction so i'm selling them together for 225 obo + shipping. thank you

how does 150 plus shipping for both pieces sound?
