California Direct-Fit Catalytic Converter

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 5551173. With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed to fit the 2009-2012 Mercedes-Benz GL450, 2009-2012 Mercedes-Benz GL550, and additional vehicles. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to comply with CARB guidelines to allow for legal use in California and CARB restricted states, for the listed vehicles.

Law
Format: Paperback
I have used this to build a Will and a Trust. Now I will take my papers to a lawyer and see if worked as expected. I think everything should be right but will wait and see. For now I give it 4 stars, but if a lawyer says it is all right, than 5 stars.

Code fails
Format: Paperback
Code failed to work on January 2, 2026. Yes it was entered correctly. Called customer service. They verified there was no issue with the code. One hour of assistance led to the agent attempting to email a huge file to me directly, which likely failed due to attachment size limitations. I cannot recommend this product at this time. Nolo needs to fix their download portal. Update: Amazon exchanged the book and the second one had a code which worked on the first try.

Great software for legacy planning
Format: Paperback
Great info. Use an AI to figure out what you need and to educate yourself, but this helps a lot for legacy planning for most of us.

We love these wipes! They smell great, they are super soft and tear resistant.. they clean well and don’t irritate our son’s sensitive skin (like other wipes have).. 10/10 recommend!
