The MagnaFlow Cat-Back Exhaust not only offers dyno-proven gains and superior fitment for your SULEV (Super Ultra Low Emissions Vehicle) model F30 328i xDrive and F32 428i xDrive, as well as all 2017 and 2018 F30 330i xDrive and F32 430i xDrive. 

Starting in 2012, BMW had two versions of the F30 328i and F32 428i engine: The standard (regular) N20 2.0 liter Turbo and the SULEV (lower emissions) N26 2.0 liter Turbo, which was found in all California, New York, Massachusetts and other states with SULEV emissions legislation. This exhaust is for the SULEV and xDrive models of 3/4 series from 2012-2016, as well as all of the 2017+ 330i and 430i (with xDrive). 

If you have a 2012, 2013, 2014, 2015, or 2016 SULEV (N26) model 328i and 428i (with xDrive) this exhaust will fit. This exhaust also fits all of the newer (2017+) B-series engine equipped 330i and 430i (with xDrive). 

The F30 328i/330i and F32 428i/430i sound just "OK" from the factory, but this is because they are designed to have a more subtle tone for the average BMW owner. There's basically only a whisper of the 328i or 428i's available performance! The MagnaFlow exhaust for F30 328i SULEV + 330i and F32 428i SULEV + 430i 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 your 2.0 liter twin-power turbo's rev limiter.

Each MagnaFlow Cat-Back Exhaust is 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.

MagnaFlow exhausts are 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 for the F30 328i xDrive SULEV and F32 428i xDrive SULEV is significantly lighter than the factory parts -- so it doesn't just look beautiful and sound great; the weight reduction actually improves handling as well.
