Peace, mercy, and blessings of God be upon you. May God bless you. A pipe that simulates the catalytic converter to solve the P0420 and P0430 code problem after emptying the converters. It is necessary for the sensor to be intact to give a correct reading, reduce the carbon smell and fuel consumption, and turn off the check engine light. If it is broken, we can provide it within a month from China at a competitive price. Contact me. The part is installed only on the rear sensors after the catalytic converter. When the codes turn off, the following problems often improve: 1- Carbon smell 2- Fuel consumption 3- Starting problem afterwards. The product was recently imported. I noticed that 8-cylinder car owners did not benefit in terms of carbon and fuel consumption; only the light turned off. A Lexus owner claims he benefited. However, for 6-cylinder cars, some benefited from fuel consumption and carbon smell, while others did not. The number of customers is very small and not enough to judge the product, and there are many videos praising it. I am only talking about my customers' experience. This product is non-refundable. You may benefit or you may not, and your purchase of it is a risk you bear the consequences of or reap its benefits. Therefore, do not buy unless you know someone who has installed it on your car and benefited, and ask other sellers, perhaps they can help you.
