When your catalytic converter requires replacement, you can install a factory-like unit that will let you pass a smog check, or you can install a Magnaflow converter that will pass the smog check and increase exhaust flow. If you want to be legal and get a performance increase, the choice is clear. Magnaflow is a performance exhaust system manufacturer, so they know all the tricks to increase exhaust flow for more power. They’ve also been producing catalytic converters for 30 years, so they’ve learned a thing or two along the way. All the exhaust flow knowledge they’ve accumulated has been packed into the design of this Direct Fit Catalytic Converter.

The heart of the Magnaflow converter is the monolithic ceramic honeycomb catalyst, which is specially designed for maximum exhaust flow and surface area. Magnaflow carefully controls the application of the precious metal catalyst to the honeycomb surface to prevent flow restriction or an emissions test failure. All Magnaflow converters have a ½” lap joint where the neck meets the body, and the neck is formed so it doesn’t extend into the converter body where it could hamper exhaust flow. As a result, the Magnaflow converter has a smoother flowing inlet/outlet joint than any other manufacturer. Magnaflow also carefully matches the size of the inlet to the converter body, because putting a larger neck on a smaller body would reduce airflow.

Besides incorporating features that increase exhaust flow for better performance, Magnaflow also builds their converters to last. The converter body is manufactured from heavy-duty stainless steel for maximum durability. All converters are seam welded close to the converter body for a strong, tight bond, not along the edge, which would allow the converter to expand and let the catalyst move around. And the aluminized steel or stainless steel heat shield creates a rigid wall of protection against heat and adds to the structural stability of the converter.

The Direct Fit Catalytic Converter is an exact replacement for your stock converter, with an interface at either end that will allow it to be bolted into the exhaust system. No fabrication or modifications are usually required. It’s available in OBD II (On-Board Diagnostics, 2nd Generation), Pre-OBD II, and OEM Grade OBD II configurations. Pre-OBD II is for early vehicles (generally 1995 or older), which were equipped with 2-way, 3-way, or 3-way with air injection converters. Two-way converters oxidize harmful Hydrocarbons (HC) and Carbon Monoxide (CO) along with secondary oxygen into water (H2O) and Carbon Dioxide (CO2). Along with the previously detailed conversion, a 3-way converter also reduces oxides of nitrogen (NOx) into Nitrogen (N2). The 3-way with air injection converter operates the same as a 3-way converter but with the addition of air pumped into the converter to improve the oxidation capabilities.

OBD II converters are for 1995 and newer vehicles and are 3-way converters. OEM Grade OBD II converters are for vehicles registered outside of the state of California, with California spec emissions. More precious metals are applied to the substrate on these converters to further reduce emissions. To determine if this converter is right for your vehicle, find the VECI (Vehicle Emissions Control Information) label in the engine compartment and look for the word “California” on the label.

On vehicles registered outside the state of California, Magnaflow warrants the Direct Fit Catalytic Converter to be free of manufacturer’s defects for a period of 5 years and emissions failure for 25,000 miles. Direct Fit Catalytic Converters on vehicles registered in California carry a 5 year, 50,000 mile warranty against manufacturer’s defects and emissions failure.

Note: Always consult emissions regulations before replacing a catalytic converter.

Sounds Great
I purchased the entire header back that was offered by MagnaFlow. So first off is the noticeable increase in power. Second, is the great sound that now my exhaust makes. The only complaint I have and they do send a warning, so it's not like I was unaware, is that I had to do minor modifications to the driver's side header and to the catalytic converter. Neither one was a direct fit. Putting that aside the system is worth every penny. I would recommend it to any Camry owner. FYI, if you are not use to a louder exhaust note be prepared. Love the sound!

MagnaFlow Catalytic Converter
Item was as described. Very easy installation, For anyone who has an 07-09 Camry 2.4 L Just make sure you remove the Alternator to get to the one header bolt. Other than that it was easy and the performance is much better than the factory.

What a Deal
When I brought my car to have a new converter installed at my local mechanic, he wanted 1700.00 including the install. Thinking that seemed too high a price, I did some online searches and came across selling the converter for 550.00, so naturally I purchased it. When I brought it to my mechanic he could not believe the price nor the quality. Anyway he charged 450.00 for the install saving me 700.00. thank you oh and yes, thanks for the free shipping.
