mufflers & exhaust

 Minute Muffler & Brake provides a large selection of exhaust products for almost every vehicle, and if not we can build it.  We have the ability to replace original equipment exhaust, manufacture and custom build.  We also have a variety of performance products.  Bullydog programmers, Headers, Cold air intakes and much more. 

 Your muffler is designed for exhaust gases to expand slowly. If the gases are allowed to expand too quickly then the resulting noise can be quite deafening.  Muffler design needs to quieten the noise of flowing exhaust gases without creating too much backward pressure on the exhaust gas flow. If too much backward pressure occurs, the free flow of exhaust gases is restrained and engine power is compromised as a result of not all of the burned gases being forced from the cylinders efficiently. As well as a loss of engine power, the fuel consumption will increase as backward pressure increases.   The exhaust system also helps prevent harmful emissions from escaping into the environment.  

 A catalytic converter is a vehicle emissions control device which converts toxic byproducts of combustion in the exhaust to less toxic substances by way of catalyzed chemical reactions.  an oxidizing reaction converts carbon monoxide and unburned hydrocarbons, and a reduction reaction converts oxides of nitrogen (NOx) to produce carbon dioxide (CO2), nitrogen (N2), and water (H2O).  There are many different types and styles of converters, but the inside is the same for the most part.  The inside consists of a ceramic monolith in a honeycomb shape.  Catalytic converters have proven to be reliable and effective in reducing noxious tailpipe emissions.
