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 \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 \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. 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.\u003c\/p\u003e \u003ch3\u003eFeatures:\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eDesigned to be as unrestrictive as possible\u003c\/li\u003e \u003cli\u003e3 inch diameter piping allows for maximum power output\u003c\/li\u003e \u003cli\u003eQuicker turbo spool\u003c\/li\u003e \u003cli\u003eEasily bolts-on u2013 no cutting or welding required\u003c\/li\u003e \u003cli\u003eDurable construction from TIG welded 304 stainless steel\u003c\/li\u003e \u003cli\u003ePrecise fitment\u003c\/li\u003e \u003cli\u003eMade in Miami, Florida\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eActive Autowerke S58 Signature Downpipe Benefits\u003c\/h2\u003e \u003cp\u003eThe 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.\u003c\/p\u003e \u003cp\u003eMinimizing 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. \u003cem\u003eNote: Because these down pipes modify the factory emissions system it is designed for off-road or racing use only.\u003c\/em\u003e\u003c\/p\u003e \u003cp\u003eAfter 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.\u003c\/p\u003e \u003cp\u003eConstructed 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!\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003cb\u003eFITS S58 VEHICLE X3M and X4M\u003cbr\u003e\u003c\/b\u003e\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003eTHIS DOWNPIPE SYSTEM IS DESIGNED FOR OFF ROAD AND RACING APPLICATIONS ONLY.\u003c\/strong\u003e\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003eBMW S58 WITH THESE DOWNPIPES WILL THROW A CEL WITHOUT AN ACTIVE AUTOWERKE SOFTWARE UPGRADE FOR OFF-ROAD USE ONLY.\u003c\/strong\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cbr\u003e\u003c\/p\u003e \u003cdiv class=\"sb-car-tag-by-description\" style=\"display: none;\"\u003eyear-2019,year-2019-make-bmw,year-2019-make-bmw-model-x3m,year-2019-make-bmw-model-x4m,year-2020,year-2020-make-bmw,year-2020-make-bmw-model-x3m,year-2020-make-bmw-model-x4m,year-2021,year-2021-make-bmw,year-2021-make-bmw-model-x3m,year-2021-make-bmw-model-x4m\u003c\/div\u003e","brand":"Active Autowerke","offers":[{"title":"X3M S58 Exhaust Upgrade Downpipes","offer_id":41121014644799,"sku":"11-064","price":1499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0046\/5770\/9120\/files\/S58NC1_139afc4f-3ec5-42ff-8636-f32a5e49de77.jpg?v=1756059897","url":"https:\/\/shop.precision-sport.com\/products\/active-autowerke-bmw-s58-x3m-downpipe","provider":"Precision Sport Industries","version":"1.0","type":"link"}
