Active Autowerke BMW S58 F97/F98 X3M/X4M Downpipe no cat **NEW PRODUCT**
**This product is a part of the Active Autowerke Motorsport Collection. It is for RACE and OFF-ROAD USE ONLY! Active Autowerke BMW X3M/X4M S58 Downpipe 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 down pipe in the S58 is a bit restrictive, which results in slower exhaust gases and slower turbo spool. The 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. 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. Features: Designed to be as unrestrictive as possible 3 inch 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 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. Note: Because these down pipes modify the factory emissions system it is designed for off-road or racing use only. 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! NOTE: FITS S58 VEHICLE X3M and X4M THIS DOWNPIPE SYSTEM IS DESIGNED FOR OFF ROAD AND RACING APPLICATIONS ONLY. BMW S58 WITH THESE DOWNPIPES WILL THROW A CEL WITHOUT AN ACTIVE AUTOWERKE SOFTWARE UPGRADE FOR OFF-ROAD USE ONLY. With heat shield

Those are nice indeed. The photos (from my standpoint) looks like they have sport cats in them...

I’m assuming these are sport cat downpipes?
Same as the ones in the link below? https://www.mlperformance.co.uk/prod...6bb83430&_ss=r Also you have mentioned these will throw up a CEL light (check engine light) but on the link I have added they list it will not bring up any CEL (check engine light?
