The Active Autowerke S58 downpipes for the X3M and X4M helps unleash some of the potential that is restricted by the OEM downpipes.\u003c\/p\u003e\n\u003cp\u003eTurbochargers are powered by spent exhaust gases created during the combustion process. The quicker these gases are evacuated, the better. Unfortunately, the factory down pipe in the S58 is a bit restrictive, which results in slower exhaust gases and slower turbo spool.\u003c\/p\u003e\n\u003cp\u003eThe Active Autowerke X3M\/X4M S58 Signature down pipe utilizes 3 inch diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability.
