High Flow Single Mid-pipe 3.5-Inch Stainless Steel

The VRSF High Flow Single Mid-pipe is engineered as a direct replacement for the factory mid-pipes on the F80/F82 BMW M3 and M4 models equipped with the S55 engine. This upgrade features a single 3.5-inch diameter, mandrel-bent, TIG-welded construction using 304-grade stainless steel, designed to significantly reduce back pressure. By removing the restrictive OEM mid-pipes, users can expect faster turbo spool, an increase in horsepower and torque, and a more aggressive exhaust note. The system offers a weight savings of nearly 20 lbs over the stock configuration. Its smooth radius bends are crafted to decrease turbulence and enhance flow. The mid-pipe is compatible with both RHD and LHD models without requiring any modifications and works with the OEM muffler as well as the M Performance Exhaust (MPE) found in Competition Pack models. Installation of this VRSF High Flow Single Mid-pipe is recommended to include the replacement of the downpipe to exhaust gaskets (2x part# 18307851168). It is important to note that this product is not for sale or use in the state of California on any pollution-controlled vehicle, as per the California Air Resources Board. The product is covered by a VRSF Lifetime Warranty against defects and fitment.
