aFe Power has introduced their all new Elite Twisted Steel Down-Pipes for the 2015 BMW M3/M4 (F80/82) with the L6-3.0L (tt) S55 engine. The performance down-pipes are available with 200 CPSI, 48-state legal cats or in a “Race” version without cats. These down-pipes are 100% TIG-welded and constructed out of 3” mandrel-bent, 304 stainless steel tubing with thick O.E. style flanges and V-band turbo flanges to ensure a leak-free seal. The smooth curves and increased diameter of the down-pipes help remove restrictions and keeps exhaust gas flowing smoothly for improved performance and durability. In testing, the catted down- pipes resulted in gains up to +21 horsepower and +23 lbs. x ft. of torque verified by our in house dyno. The down-pipes also retain factory 02 sensor locations and include all necessary hardware along with gaskets for a true bolt on application.
