Please note: This exhaust is designed to fit the E46 chassis 323/328 models. If you have a 1999 model 2-door coupe or convertible, you have an E36 chassis and this exhaust will not work.
The MagnaFlow Cat-Back Exhaust for all 1999 and 2000 model E46 323i & 328i 4 door sedans, and 2000 model 323Ci & 328Ci coupe/convertible not only offers dyno-proven gains and superior fitment, it also makes your E46 323/328 sound the way it should've from the factory.
Unless your E46 323/328 has a rust hole or exhaust leak (which by now, it may suffer from) you probably can't hear the exhaust note all that well. The M52TU power 2.5 liter in the 323i/323Ci and 2.8 liter in the 328/328Ci sounded pretty quiet from the factory. This is because they were designed for the average non-enthusiast BMW owner. With much added restriction built into the heavy factory exhaust, there's only a whisper of the M52TU engine's available performance. This MagnaFlow exhaust for your BMW cures that problem by using a wide-open performance muffler, giving your 323/328 a tastefully 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 your 323i / 323Ci / 328i / 328Ci BMW's 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 parts, so it doesn't just look beautiful and sound great - it improves handling as well.
