Joe gandy Posted May 22, 2020 Share Posted May 22, 2020 Hello everyone, in desperate help as I cannot find it anywhere, I have an Audi a4 b7 with a k04 hybrid conversion. It's has a decat downpipe system on it and need to find a cat downpipe for emissions but haven't had luck finding a K04 downpipe for my car! I cry for help and I'm grateful if anyone can help me!

Steve Q Posted May 23, 2020 Share Posted May 23, 2020 As what you have sounds specialised I'd recommend you look at an aftermarket performance cat by demon tweeks or similar band have it custom made for your car. Quote Link to comment Share on other sites More sharing options...
