If you don't have enough money for a down pipe and cat assembly, this is the way to go

Both catalytic converters were great with excellent pricing and received in a timely matter. I recommend others to purchase from parts geek with reasonable prices and great customer service

Perfect fit. Perfect price. Fast shipping. No more check engine light.

2004 Audi A4 Catalytic Converter

Very Satisfied
Reviewer: It works and great savings

I had this installed on my 2007 Audi A4 and it works well. I passed my emissions test, no engine light or cat inefficiency code as well. Its 1/4 the cost of the dealer model and I expect that it may not last as long as the more expensive models, but its a great value and comes with a 5 year warranty.
