BMW Exhaust System Upgrades for BMW 3 Series E46 (1999-2005)

Clear BMW chassis
A performance exhaust is a modification that you get constant benefit from - at every change of the throttle you are rewarded with that tuned sound. It's not like other modifications where you may not realize all of its benefits all the time. It's an upgrade that you enjoy at all times when you're behind the wheel. We offer exhaust upgrades from multiple performance manufacturers like Borla, Corsa, Supersprint, and Akrapovic but we have also developed or sourced other exhaust systems to meet specific needs.

The Active Autowerke Exhaust SECTION 1 only comes into play if the E46 M3 already has a performance header already installed. One will experience a high smell of unburnt fuel. (due to the open exhaust w/o any catalysts) and development of a RASPY like sound of which the BMW S54 engine is notorious for with the BMW Stock Section 1 when equipped. This raspy like sound is a matter of engine sound harmonics at a specific RPM range, a sort of resonance that is very loud and noticeable when the engine is revving at or above 4,000 rpm

With the Active Autowerke Exhaust SECTION 1 installed, the BMW performance gains are about the same as running the factory section 1. However, that's impressive considering the exhaust flow is also being filtered while running through a pair of 100 cell catalysts. The power and performance is still there.

E46 Section One Features:

  • Dyno-tested & Track Proven
  • Brushed 100% 304 stainless steel construction
  • Pair of 100 CELL Hi-Flow metallic exhaust catalysts included
  • Easy installation, no instructions necessary
  • Two-year warranty with free tech support

High flow exhaust system directly from aFe, one of the top after market performance manufacturers. In recent testing this system produced 15 horsepower and 13 lbs. x ft. of torque. This exhaust system is constructed from 3.0aEUR mandrel bent stainless steel and is hand TIG-welded. The system uses a high flow transverse muffler with 3" diameter tubing which improves performance across the power band while maintaining a great tone. To finish off this exhaust are dual double wall resonated angle cut gloss black 304 stainless steel tips. The factory actuator drive is retained with the aFe exhaust so that a check engine light does not occur. This exhaust uses all factory hanger locations for a hassle free installation.

This is the exhaust for the Spec E46 racing series and listed in the SE46 rules ( http://spece46.com/spece46-regulations/ ). Per SE46 rules, this must be used with stock E36 OBD-II exhaust manifolds that are sold separately. Together with the E36 manifolds this complete system eliminates the catalytic converters without the need to extensively modify the stock E46 exhaust. It's Made in the USA by Magnaflow with 3" stainless and mandrel-bent piping. The entire system, especially the front Y-pipe, has been designed to provide the least exhaust obstruction and promote flow. The front Y-pipe and merge collector simulates an equal-length header when used with the E36 OBD-II manifolds. V-band clamps make it easy to work on the exhaust or chassis in sections rather than dropping the entire exhaust system. A center resonator and rear muffler have been designed to cut noise levels for the more restrictive tracks.

E36 OBD-II exhaust manifolds required (1996-1999 E36 328i/M3). These can be purchased new but good used manifolds should be easy to find.

This is a race-only part and intended only for use in the Spec E46 racing series. Because this part alters or deletes the emissions equipment on your car we require a waiver of emissions compliance to be signed and sent in to Turner Motorsport. You can download the waiver here.

This item fits the following BMWs:

Rogue Engineering IKON Axle-Back Exhaust - E46 325/330

What makes the IKON unique?
Like all Rogue Engineering products, the IKON exhaust system is entirely designed and developed in the US in our facility in Hohokus, NJ. By doing the development, fitting, evaluation, and testing here, you're assured a product that not only looks and sounds great but a product you can have installed with confidence.

The budget-minded enthusiast will quickly notice that the first IKON offering, for the BMW E46 325/330 is price much lower than our DMS exhaust. With a price of only $550, this is undoubtedly the most affordable BMW specific exhaust offered to date. Isn't it time an affordable exhaust solution be available for the E46?

By utilizing a custom-made, single muffler (instead of producing two, individual mufflers in our DMS system), Rogue was able to save manufacturing costs with this simpler design, and pass this savings to the performance customer. Many enthusiasts do not pay particular attention to the shape or size of the muffler, as long as it fits well and sounds good. The RE IKON fits this bill perfectly.

How much performance should I expect to gain?
In testing, replacing only a muffler or even the complete exhaust system on an E46 yields small measurable gains. Of course, these minute gains may be depicted on a carefully constructed dyno chart. Rogue Engineering looks at an exhaust with reality in mind, designing the exhaust to deliver great looks and sound, with minimal issues of fit. Of course, all of this at an affordable price would be a bonus. These are features that the Rogue Engineering IKON deliver!

For real-world exhaust performance gains, this typically means replacing the largest restriction, the catalytic converters, located in the factory exhaust manifolds. From there, free flow aftermarket catalytic converters could be added downstream, after the exhaust gas velocity had an opportunity to accelerate out of the engine, allowing for the most LEGAL gas velocity allowable. This course of action, however, can typically can exceed more than $3000 plus installation.

Replacing the ENTIRE factory exhaust system (resonators and rear muffler) with larger tubing WITHOUT addressing the largest restriction is an exercise in futility. This kind of exhaust "upgrade" will generally cost needless additional installation charges, fit issues (can 6 clamps on an exhaust REALLY fit like factory?), and ultimately, drain your wallet faster than a Bugatti Veyron.

IKON Features
Just because the IKON exhaust system is easy on the wallet does not mean you are getting short-changed. Features of the RE IKON E46 system include:

  • Only 21 pounds (replaces the 30-pound unit from the factory)
  • Full 304 Stainless Steel construction
  • Mandrel bent, dual 57mm tubing (stock is dual 50mm), allowing for increased air flow yielding positive performance gains.
  • Mill-finished pipes and muffler, mirror polished dual 3" angle cut, double-walled, staggered tips.
  • Entire exhaust utilizes TIG welded construction
  • Deep tone (stock center resonator is retained)
  • Maintains BMW factory warranty
  • Rogue Engineering logo tastefully stamped in the body of the muffler
  • Adjustable mounting positions allow variable positioning with aftermarket bodywork
  • Can be clamped or welded (because factory exhaust must be cut, professional installation recommended)
