"Replaced entire exhaust and this item was part of it. Couple days for shipping arrived undamaged had everything welded and installed and sounds great. This is a fraction of the cost of a direct fit/bolt on converter so was pretty much a no-brainer." posted by: on May 18, 2014

"i bought both left and right side. passenger side was installed with no problem. driver side though was a real headache. it wouldn't fit correctly. I ordered another one from different company (same part number) and it was the same problem (actualy this time it was even worse). I don't know what is with Bosal i thought that they were making quality parts. at the end i have to cut, adjust properly and weld it back. Wrote to Bosal, still no response... In future i'll try to avoid BOSAL" posted by: KK on January 10, 2011

Bosal Catalytic Converter

The catalytic converter from Bosal is engineered to fit directly on most types of street cars, and it doesn't require labor-intensive pipe bending or cutting. Aside from its easy-to-install feature, the catalytic converter is built with a 16-gauge, fully aluminized tubing that allows the consistent flow of exhaust and limits engine backpressure. Specifically designed with a ribbed, oval body for durability and stability, the Bosal catalytic converter contains a monolithic honeycomb catalyst that reduces the harmful effects of the exhaust gases. Although this catalytic converter is only 49-state legal, it comes with a 5-year or 25,000-mile Bosal warranty that ensures the durability of the product.

Eastern Catalytic Catalytic Converter

Designed with NANO technology to withstand extreme temperature and reduce significant amount of backpressure, the catalytic converter from Eastern Catalytic ensures maximum performance for most types of cars. The ceramic catalyst inside the catalytic converter has 300 cells per square inch that let the gases flow smoother compared to a standard catalyst that only has a total of 400 cells. Apart from that, the ceramic catalyst can also lessen the engine backpressure by at least 8%, thus increasing the engine's horsepower and torque. Consumer-friendly and easy-to-install, the bolt-on type catalytic converter has different inlet and outlet sizes to ensure a perfect fit.

EvanFisher Catalytic Converter

Made from high-quality and durable stainless steel, the EvanFischer catalytic converter is designed for optimum performance under high-temperature for a long period of time. It has a honeycomb catalyst that allows maximum exhaust flow, and 16-gauge aluminized steel tubes that reduce backpressure from the engine. It also has a heat shield that gives more durability and protection. The catalytic converter contains two oxygen ports and a single inlet and single outlet configuration. With a silver, powder-coated, oval body, the catalytic converter is easy to install because the gaskets are already included and doesn't require cutting or welding. The catalytic converter is 49-state legal and has a two-year or 25-000 mile EvanFischer warranty.
