BMW Exhaust Parts, Mufflers & Catalytic Converters for BMW 3 Series E46 (1999-2005)

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)

Exhaust gaskets should be replaced any time the exhaust is taken apart or when a leak occurs. This Elring gasket is perfect to prevent any future leaks and to fix old ones.

Elring is one of the biggest OEM names in the manufacturing of high quality gaskets that are available for very affordable prices. Elring has supplied many automotive names for years with the gaskets that seal your car's components from day 1 so you can rest assured that these components will last for a long time to come!

OE BMW exhaust manifold mounting hex nuts. Best to replace when installing new headers or removing the old exhaust headers for any reason. We also recommend replacing the exhaust studs as well do to corrosion often building up on the end, preventing them from being removed or installed easily.

Crafted from high-strength 6031 billet aluminum and finished in a sleek black anodized coating, it delivers both durability and corrosion resistance. With this collar in place, your exhaust stays exactly where it should—no rattles, no surprises.
