Active Autowerke Racing Catless Downpipe for the BMW S58 F97 F98 X3 M & X4 M.

Please Note: **This product is a part of the Active Autowerke Motorsport Collection. It is for RACE and OFF-ROAD USE ONLY!

BMW introduced a new valvetronic, single turbo version of its direct-injection engine for the later F-Chassis models beginning in 2016 and continues into the G-Chassis models - the evolution to the S58 engine continues with the twin turbo variant used in the M-series vehicles. The Active Autowerke S58 downpipes for the X3M and X4M helps unleash some of the potential that is restricted by the OEM downpipes.

Turbochargers are powered by spent exhaust gases created during the combustion process. The quicker these gases are evacuated, the better. Unfortunately, the factory downpipe in the S58 is a bit restrictive, which results in slower exhaust gases and slower turbo spool.

The Active Autowerke X3M/X4M S58 Signature downpipe utilizes 3-inch diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability. We've incorporated stainless flex joints and then down to 70mm to meet the OEM exhaust system. We never drop the diameter to smaller than the stock diameter of 70mm.

 

  • Casted upper stainless steel V-Band for precise fitment
  • 4.50" diameter piping allows for maximum power output
  • Quicker turbo spool
  • Easily bolts-on no cutting or welding required
  • Durable construction from TIG welded 304 stainless steel
  • Precise fitment
  • 304 stainless steel substrate is furnace braised to the mantle for outstanding durability
  • Ideal for Forced Induction Applications with no loss of HP
  • Made in Miami, Florida


Active Autowerke S58 Signature Downpipe Benefits

The speed of a turbo's impeller wheel is limited by exhaust back pressure. A larger down pipe relieves some of this pressure, resulting in quicker and more efficient spool. With Active Autowerke's Signature downpipes, your S58 can rev quicker, and deliver more horsepower and torque.

Minimizing back pressure while retaining daily drive-ability was the goal of our S58 downpipes. Owners can now upgrade to a product that is affordable, reliable, and easy to install.

After months of research and development, our engineers settled on a 3 inch diameter pipe which utilizes the least number of bends possible. The large volume helps the turbo spool as quickly as possible by eliminating back pressure during spool up.

Constructed entirely from 304 stainless steel with 1.5MM wall thickness, we are confident that you'll be pleased with how robust and durable this down pipe is. Trouble-free installation and a long lifespan ensure that you'll enjoy many miles of performance with your S58!
