Senior Aftermarket was introduced in the 1990’s to serve the impending requirement of catalyst related products entering the aftermarket for the first time.

Since then we have witnessed the evolution of the exhaust system and the introduction of catalyst based systems in other markets that means we now operate in many more markets than just passenger car – where we started almost 30 years ago.
