The MagnaFlow Cat-Back Exhaust for your 2001-2005 325i/330i not only offers dyno-proven gains and superior fitment, it also makes your E46 sound the way it should've from the factory. Fits E46 coupe and sedan models with manual transmission only.

MagnaFlow has two systems for the E46 325i/330i: this system and part #16748. The difference is that this system includes flanges for a true bolt-on to the stock manifolds and adds a 330-tuned front resonator. This is a complete bolt-on solution from the catalytic converter back. If you're looking for the "full" cat-back system for 325i/330i you should consider this system over the standard cut/clamp version we also offer. You can view a schematic of the full system by viewing the instructions PDF below. 

Not for convertible models or cars with automatic transmission. 

Most BMWs sound nice from the factory, but they're designed to have a more subtle tone for the average BMW owner, so there's only a whisper of the available performance. MagnaFlow's full E46 cat-back system cures that problem with wide-open performance mufflers that offer a moderately aggressive sound. The smooth, deep tone is suitable for mild-mannered street cars driving around town, yet it opens up nicely under wide-open throttle to have you smiling all the way to the rev limiter.

MagnaFlow Cat-Back Exhausts are constructed of 100% polished stainless steel. The mufflers are lap-joint welded for solid construction and rugged reliability even in the most extreme conditions, and they feature a free-flowing, straight-through perforated stainless steel core, stainless steel mesh wrap, and acoustical fiber fill to deliver the performance and sound your car deserves.

Each MagnaFlow exhaust is designed to provide years of trouble-free performance with better-than-stock looks, plus a lifetime warranty to back it all up. Plus, the MagnaFlow Cat-Back is significantly lighter than the factory 330i exhaust, so it doesn't just look beautiful and sound great - it improves handling and power-to-weight ratio as well.

  • Dyno-proven gains
  • Superior fit and finish
  • Neighborhood-friendly sound on the street
  • Full German-American soundtrack at wide-open-throttle
  • Exceptional weight savings

325i Note: the system pipes and muffler were designed around the larger 330i engine. Based on our experience there is more drone in a narrow RPM range on the 325i models.
