B6 3.0 Cat delete. need advice
I have a 2002 A4 quattro B6 3.0 manual. I need a new exhaust so I figured I would just upgrade from stock. Also my cats are bad and need to be replaced. luckily where I live they don't do emissions testing. Can I just buy headers to totally cut it out? and if so any brand suggestions? I was planning on putting in a spacer on the O2 censor bung so it wont throw a code. Any advice would be great! thanks

after doing some research I understand they don't make headers for the 3.0 and the spacers don't really work. I've come to the point where i'm just going to find a high flow cat set up. does anyone know of a brand that wont cause the car to throw codes with out having to have it tuned?
