BMW Downpipes for BMW X6 M S63 4.4L

Clear BMW chassis

Please ensure your correct model is selected

When BMW began to offer more and more forced induction vehicles, some enthusiasts were upset and others were excited about the big power potential. While we love older, naturally aspirated BMWs, we LOVE forced induction BMWs. Upgrading your downpipe (or downpipes) is one of the easiest ways to reduce restriction and add more power to your BMW. We offer several brands, including our own designs, of downpipes for your BMW!

The stock down pipes cause a major restriction in the exhaust flow. BMW's solution to deal with the limited space in the engine compartment is to crush the turbo outlet tubes to reduce the size of the tubing. Doing this created undesirable backpressure. For emission purposes the factory also incorporated built-in pre-cats directly after the turbo outlet ports. This make the exhaust gas backpressure rise to extremely high levels at all rpm and engine loads. This design retains excessive heat in the engine and affects performance in a negative way. The design of the Supersprint down pipes takes advantage of even the smallest space available and frees the exhaust gas flow dramatically. The SS pipe cross section (no crushed pipe) remains constant all along the down pipes and the pre-cats are totally eliminated.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Restrictions in the exhaust system rob horsepower and torque, especially on turbocharged cars. Thus, removing as many exhaust flow restrictions as possible will increase horsepower and torque significantly. The factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction. Evolution Racewerks use a 200 cell metallic core for their Sports Series High Flow Catted Downpipes. By having fewer cells per square inch, these individual "cells" are bigger in size thus allowing exhaust gas to pass through them more easily. Therefore, the lower the cell count, the higher the flow. Higher flow = more power, faster turbo spool up (less turbocharger lag) and better throttle response. Bottom line, faster. The benefits of a metallic catalytic converter vs a ceramic, like the factory, is that it can take higher temperatures and is more durable (last longer). They are also lighter than their ceramic counterparts. The Evolution Racewerks catted downpipe is constructed out of grade 304 stainless steel and utilizes mandrel bent 3" piping. They are 100% TIG welded by in-house fabricators and built in the USA. The factory turbocharger turbine housing utilizes a V-Band flange which has been duplicated and CNC machined cut out of billet 304 stainless steel. Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods. The O2 sensor is positioned at the factory location. Evolution's downpipes are designed to fit perfectly with either the factory exhaust system or your aftermarket exhaust system. There are no compatibility issues whatsoever with any exhaust designed to bolt up to stock downpipes. The downpipes will come by default with a brushed finish. Features & Specifications: High Flow 200 cell metallic catalytic converter used Higher Max Horsepower Power Curve Higher Initial Torque Curve. Torque curve hits faster and higher and longer. Mandrel Bent 3" piping. Smooth transition to the exhaust system - Better throttle response and faster turbo spool-up times. 100% Stainless Steel Construction 100% TIG welded for better quality welds Precision CNC machined turbocharger V-Band flange. Retains factory slip-on style connection. Compatible with the factory or aftermarket exhaust systems. Track tested durability. Includes all hardware for complete installation. Limited Lifetime Warranty. CAUTION: This product is intended for OFF ROAD COMPETITION USE ONLY. Not legal for use on pollution-controlled vehicles upon public roads/highways. THIS PRODUCT IS FOR SALE FOR ALL 49 STATES EXCLUDING CALIFORNIA. THIS ITEM IS NOT FOR SALE, INSTALLATION, OR USE ON LICENSED VEHICLES IN THE STATE OF CALIFORNIA.

The S63 and N63 twin-turbo V8s are world-class powerplants, but they’ve got a breathing problem. From the factory, your BMW X5M, X6M, 550i, or 650i is suffocating under massive backpressure caused by restrictive, bulky catalytic converters that trap heat and kill momentum. If you want real power, you have to let those turbos spin. Active Autowerke’s Signature High-Flow Downpipes are the ultimate "no-compromise" upgrade for the serious BMW enthusiast. Hand-fabricated in Miami, these 3.0" downpipes utilize GESi G-Sport Ultra High Output technology. You get the raw performance and rapid spool of a track setup with the refined, odorless experience of a daily driver—and most importantly, no Check Engine Light. Why These Downpipes Belong on Your BMW: Turbo performance is all about the pressure differential. By clearing the path behind the turbine wheel, you allow the turbos to work significantly less to produce significantly more. Instant Turbo Response: Experience a massive reduction in lag with quicker spool-up and instant throttle tip-in. Massive Power Ceiling: The 4.5" GESi 400-cell cores are rated for 500hp to 850hp, ensuring they won't become a bottleneck as you climb the ladder of modifications. Clean & Odorless: Forget the "gas station" smell of catless downpipes. These proprietary precious-metal catalysts keep the air clean and your cabin comfortable. Hand-Built Precision These aren't mass-produced units. Each set is TIG-welded 304 stainless steel with cast upper V-band flanges for a factory-perfect, leak-free seal. Because Active Autowerke builds these in-house, the fitment is surgical—designed for a straightforward bolt-on installation with no cutting or welding required. Turner Fitment Note: To guarantee 100% accuracy for your build, please provide your VIN at checkout. Note: These are F-chassis specific; G-body vehicles with the N63B engine require a different configuration. Core Features: No CEL Guarantee: Optimized for catalytic efficiency to keep your dashboard clear. 49-State Legal: EPA Registered and fully OBD2 compliant (Excludes CA). Built for Heat: Rated to withstand up to 1,500°F and reaches operational efficiency in just 9 seconds. Legendary Durability: 304 stainless substrate is furnace-braised to the mantle for maximum vibration resistance. Warranty Protected: Includes a 5-year/50,000-mile structural warranty and a 2-year/25,000-mile catalyst core warranty.* Technical Specs: Material: TIG-Welded 304 Stainless Steel Tubing: Full 3.0" (76mm) Mandrel-Bent Piping Catalyst: GESi Ultra High Output (400 CPI) HP Rating: 500hp - 850hp Lead Time: Custom made-to-order (Approx. 2 weeks) *A Note on Burble Tunes: We love a good exhaust crackle as much as anyone, but "aggressive" burble or pop maps physically destroy catalytic substrates. Use of such tunes will void the warranty on the GESi core.

There are no compatibility issues whatsoever with any exhaust designed to bolt up to stock downpipes. The downpipes will come by default with a brushed finish. Ceramic Thermal Coating - The purpose of ceramic coating downpipes is to keep heat from the exhaust gases inside the downpipe from radiating out. This keeps underhood temperatures lower and less heat absorption by nearby parts/surfaces. Another added benefit is that by keeping in heat (energy) in the exhaust gases inside the downpipe, exhaust flow velocities stay up, resulting in lower backpressure. The ceramic coating also adds additional corrosion resistance. Evolution utilizes the best ceramic coating possible. Their thermal coating can resist up to 2000F of heat. It is available in black only (all the other colors cannot withstand the heat that high).
