One comment.... not sure what you mean by 'poor maintenance'.


Only issues with air/fuel ruin cats...did you fix those issues?




Funny story. MANY years ago I needed a cat for a VW scirocco. Went to a junk yard, dump young kid, and asked if they had any. Counter guy looks me over, says 'cant sell them, thats illegal'. I was crestfallen. Incredulous.... 'really?!?'..... he locked eyes and asked "maybe you mean the pre-muffler?". I pause a beat, and said "Oh, yeah- I need a pre-muffler".
