" This is not a direct replacement for a BMW Z3. You will need to cut the exhaust and weld in some elbows. It fixed my catalyst problems but plan on taking it to a muffler shop or have your wire welder ready. "

" Finally...my engine light is off!!! I never heard of JC Whitney prior to my purchase. I'm always cautious of ordering anything online, but the Catalytic Converter came within 3 days of my order and fixed my car. Great company good customer service and they actually pick up their phone when you call. no automated system. lovely!! I have much more work to do on my Honda, now I have a company I can trust. "
