RM Motors is a Poland based manufacturer, producing locally designed and hand-made downpipes from high quality raw materials. Selection covers a great variety of brands and models, as well as universal accessories and components for exhaust systems. Price/quality ratio is exceptional.

Main types of Downpipes

• RACE, so called decat, track downpipe. Strongest exhaust note, but generally not approved for road use as it doesn’t pass emission tests. (Check your local regulations)
• 100CPI Euro3 catalytic, a compromise with high flowing 100CPI matrix which filters the worst of the smells and odors while softening the exhaust note a bit.
• 200CPI Euro4 is the best seller, high flowing 200CPI metallic matrix. Filtration capacity meets allowed emission levels in most tests and vehicles (Check your logal regulations). Doesn’t restrict your exhaust flow in any significant way.
• For limited models, you can find additional OBD, EURO6 or FIA certified catalytic converters.

Catalytic converters

RM uses only catalytics of the highest quality. These cells can handle spiritful driving and tuned engines with ease. In most cases, the flow of a 100 or 200CPI cat won’t be different from a straight pipe in any way that would affect your cars performance.
