The MagnaFlow Performance Exhaust for either your 2001-2005 325i & 330i, or 2001-2006 325Ci & 330Ci coupe not only offers dyno-proven gains and superior fitment, it also makes your 2.5 or 3.0 liter E46 sound the way it should've from the factory. This system installs just after the stock front resonator, using a very simple cut/clamp installation (see the full instructions below.) The results of this exhaust are superb, and make any RWD non-convertible 325 or 330 models sound fantastic!
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. This E46-specific exhaust cures that problem with free-flowing 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 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 acoustic fiber fill to deliver the performance and sound your car deserves.
Simple Cut/Clamp Install - Just like many BMW Performance Exhausts
This performance exhaust installs by cutting the stock front resonator section and clamping the complete MagnaFlow system downstream of the front resonator. The location for the "cut" is a very straight section and is an easy way to retain the front cats and resonator (keeping the car street legal) but enhancing the sound and performance by mating MagnaFlow components downstream.
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 system is significantly lighter than the factory parts, so it doesn't just look beautiful and sound great - it improves handling as well.
