We now offer an improved range of both 100cpsi cats and 200cpsi performance cats, which come standard with a stainless steel monolith. Having fewer cells per square inch improves the gas flow through the catalytic converter, and can boost performance by up to 15bhp. The stainless steel monolith gives extra longevity, especially on lowered vehicles.

BM Catalysts can supply a wide range of universal catalysts with both metallic and ceramic monoliths that are suitable for both petrol and diesel engines. They are available in a variety of lengths and bore sizes. All our unicats are manufactured neck-less but stubs of any bore can be welded in for a small additional cost at the time of purchase.
