DEC Catalytic Converters

DEC has more than 26 years specializing in the manufacture of replacement catalytic converters that fit properly and perform efficiently. You will not find their quality and expertise from other manufactures. All DEC products are assembled in dedicated Steel Jigs using machined mounting flanges, silent flex tubes, heavy duty tubing, heavily loaded substrates and precision stainless steel shells to assure the proper fit. They have a skilled, quality team that is dedicated to providing the best parts in this industry. Their experience assures you that the product they produce is of the top most quality. Their post manufacturing quality control staff gives them the additional insurance of that top quality. An experienced DEC quality control specialist fits all assembled parts into a completed jig to verify all dimensions. This unique concept of dedicated steel jigs for each model assures perfect fit and repeatability.

Exhaust

Burning fuel in the engine of your BMW or MINI produces a lot of sound along with nitrogen oxide, carbon monoxide, hydrocarbons and other harmful gases during the combustion process. Your vehicle's exhaust and emissions system helps control some of that sound and cleans up the gasses in the process of routing them out of the engine bay.

For more than four decades, Bavarian Autosport has been helping BMW and MINI enthusiasts maintain, repair, and upgrade their vehicles while saving thousands of dollars in shop fees. Throughout our history it has been our mission to give every BMW or MINI owner the resources to take on nearly any repair or maintenance task themselves. With more than 100 DIY videos and free tech help available on our site, there is no job that is too big. We have a full team of advisors ready to answer your technical questions and help you find the right part for your BMW or MINI by phone or email. And if you aren't 100% satisfied with your purchase, returns are easy and hassle-free.
