Review on 🚀 MagnaFlow Universal Catalytic Converter HM Grade Federal/EPA Compliant 99306HM - Stainless Steel 2.5in Inlet/Outlet Diameter, 15in Overall Length, Post Converter O2 Sensor - HM Replacement: High-performance emissions control solution by Brant Watson

Got rid of the hum of the engine, not to mention the exhaust. Code P0420 also solved. Look at the old cat I cut off my car. Completely empty! I have no idea where the catalytic converters went because the resonator and muffler were clean too. I've also included a photo of the new Magnaflow cat before welding. I tried the clamps but they wanted to leak so I had to squeeze. Anyway, the car drives so well now! Just like old times. Two thumbs up Magnaflow! I drive a 2000 Buick LeSabre Custom. I will update if anything changes.
