BMW E82 Performance Exhaust Systems

BMW E82 Performance Exhaust Systems BMW Performance exhaust systems are tuned by in-house BMW engineers to subtly enhance the sound and performance of your BMW. They have engineered these systems to fit perfectly, sound beautiful, utilize advanced materials, and blend with the styling of your car. BMW Performance exhausts are not too loud - focusing on enhancing the sound rather than blaring it. By opening up the exhaust and removing restrictions, the engine can work less to move the exhaust gasses through the system. This means a bit more power in addition to that sexy growl they produce.

AFE Twisted Steel Downpipe with Cats - E9x 335i, E82 135i (N55)

Features:

  • In house testing produced a max gain of +14 horsepower and +39 ft. lbs. of torque verified by our in house dyno (results from the "Race" version down pipe)
  • This system utilizes a 400 CPSI (cell per square inch) 48-state legal catalytic converter for maximum flow
  • A unique 2.5" to 3" stepped design is used to increase exhaust velocity
  • Constructed of durable mandrel bent brushed 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking
  • 100% hand TIG-Welded by certified craftsmen for race proven strength and durability
  •  
  • aFe power introduces an all new Elite Twisted Steel catted down pipe for the BMW 335i (E9x) /135i (E82/88) 11-13 with L6-3.0L (t) N55 engine. This down pipe is designed using a 48-state legal 400 cpsi catalytic converter and mandrel-bent, 304 stainless steel tubing for optimum flow resulting in added horse power and torque. The down pipe is 100% hand TIG-Welded and uses a 2-1/2" into 3” stepped design that increases exhaust velocity and eliminates low pressure drops which helps to scavenge the exhaust for increased intake charge and more power.

    48-State Legal Catalytic Converter:
    This system utilizes a 400 CPSI (cell per square inch) 48-state legal catalytic converter for maximum flow.

    2-1/2" to 3" Stepped Design:
    A unique 2.5" to 3" stepped design, is used to increase exhaust velocity and increase usable torque. This means more aggressive throttle response and increased passing power.

    TIG-Welded: 
    100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks.

    Brushed 304 SS Construction:
    This down pipe is constructed of durable mandrel bent brushed 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking.

    Hassle-Free Installation:
    All hardware and brackets are included for a hassle-free installation. This unit also comes with a 2-year warranty.

    Also Fits:
    BMW 135i (E82/88) 10-14 L6-3.0L (t) N55
    BMW 335i/xi (E90/92) 09-13 L6-3.0L (t) N55
    BMW X1 35xi (E84) 09-15 L6-3.0L (t) N55

    aFe down pipes are engineered and manufactured in our Corona, California manufacturing facility.

This product modifies (but does not remove or defeat) emissions equipment. For this reason this product may not be CARB compliant, and therefore not emissions legal in some states. Consult local laws and regulations in your area. For more information on this product, feel free to contact our sales department.

Active Autowerke Signature Exhaust Muffler Generation 2 - E82 135i

After months of testing this system with various size piping AA's engineering team decided that 3.5” piping is the best suited size for a true free flowing design on the BMW 135i exhaust. The increase in piping size decreases back pressure allowing the BMW 135i’s twin turbo to spool even faster resulting in increased horsepower and torque throughout the entire RPM range. This was the design feature of the GEN 1 E82.

However, when a set of Down Pipe was installed, some customers experienced a higher sound decibel tone with the total package.

What they created was the development where no increase in the decibel level was noted, even with the addition of a set of down pipes. The solution is the creation of the GEN 2 Signature Rear Exhaust. 

The 3.50" stainless steel exhaust tubing was still maintained to keep the power, but the addition of a High Flow sound regulating muffler was incorporated. This design showed no decrease in power and successfully lowering the decibels.   

Manufactured from 100% polished 304 stainless steel this bolt on system is well suited for the BMW E82 135i owner who wants a louder than stock but quieter than gen 1 exhaust with down pipes.

FEATURES:

  • Full 304 stainless steel with hi-polish finish 
  • 3.50" Mandrel Bent Piping for Optimum Exhaust Flow
  • High Flow sound regulating muffler 
  • Dual 80 mm Active Autowerke Signature tips mounted staggered 
  • Measured 5-7+ horsepower increase at the rear wheels on the Active in-house chassis  dyno 
  • Designed to use existing factory mounts and hardware
  • Full adjustable mounting positions 
  • True Bolt On System

AFE Twisted Steel Cat-Less Downpipes - E9x 335i E82 135i 2008-2010 (N54)

The aFe Power Twisted Steel, cat-delete, race down-pipes eliminate the catalytic converters for maximum exhaust flow for the popular BMW 1 series and 3 series with the N54 twin turbo motor. In recent dyno testing, these race pipes produced 17 horsepower and 32 x ft. torque over the factory down-pipes. These high performance race pipes are constructed out of lightweight, TIG-welded, 3 inch, brushed finish, 304 stainless steel and use thick 3/8 inch 304 stainless steel flanges for a leak-free seal and a factory fit.

All aFe exhaust systems are engineered and manufactured in the Corona, California manufacturing facility.

Tig-Welded:
100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks.

Factory O2 Sensor Locations:
These down-pipes use factory mounting locations for the O2 sensors.

Hassle-Free Installation:
All hardware and brackets are included for a hassle-free installation.

Note: This is a "Race Only" product used solely for competition. Its use is limited to closed-course and open-course racing that is formally sanctioned by a recognized racing organization. Any other use including recreational off-road use could be in violation of local, state and federal laws. A check engine light will emit and aFe recommends using a programmer but it is not necessary.

This part alters or deletes the emissions equipment on your car, and may not meet emissions standards in all states. Because of this, we require a waiver of emissions compliance to be signed and sent in to TMS. You can download the waiver here.

AFE Twisted Steel Headers - E9x 325i 328i 330i 2006-2013, E82 128i

aFe Power’s new “Race Only” Twisted Steel Headers deliver an astounding 16hp and 18lbs. x ft. torque while outflowing the factory exhaust manifolds. The headers are constructed of near equal length 1.5” 16-gauge 304 stainless steel tubing with thick flanges to ensure a leak free seal. To eliminate dead space that can cause turbulence and hinder flow that formed collectors are prone to produce, true merge collectors and optimized tube lengths are used for true pulse control technology improving flow and performance. 100% TIG-welded, the smooth curves and increased diameter of this header helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability. It uses dual, high flow, 300 cell catalytic converters for maximum flow providing an astonishing low end torque improvement. All components are supplied for a hassle-free installation with no modifications necessary.

Tig-Welded: 
100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks.

Dual High Flow Catalytic Converters:
The semi-metallic 300 cell catalyst is designed for maximum surface area and flow.

Retains Factory Sensors:
aFe has designed this system to retain all your factory sensors for a hassle free installation. Also included are 6 O-ring header flange gaskets.

Mitered Collectors: 
Mitered collectors not only extend the tube lengths and decrease turbulence, but provide optimal exhaust scavenging. The result is increased horsepower, torque and improved throttle response.

304 SS Construction: 
These headers are constructed of durable CNC mandrel bent brushed 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking.

aFe headers are engineered and manufactured in our Corona, California manufacturing facility.
