The Buick Regal Catalytic Converter is a part which lowers the quantity of carbon monoxide gas emitted by your vehicle's exhaust, allowing you pass the emissions test. Situated inside the exhaust system of a car or truck, the Buick Regal Catalytic Converter functions to minimize the entire toxic emissions of the car or truck's by catalyzing a chemical reaction in your emissions. Buick Regal Catalytic Converters work by oxidizing pollutants into harmless water and CO2, using a metal catalyst, often platinum, and expelling the catalyzed gas out the tailpipe. No matter whether you drive an exotic sports car or a minivan, we have the parts and accessories you are searching for right here at www.partsgeek.com.

What can I say. Flowmaster corrected not only the code issue but made my Buick Regal breath the way it was meant to. Nice and quiet, easy install, fit was perfect with minor retrofit need. Fast delivery and as for looks, it's everything my exaust system needed. Thanks Parts Geek. I'll be back for more parts in the near future. - MoreFlow!!
