The Spec E46 exhaust system is a lightweight 3″ stainless steel exhaust that includes all necessary from rear of the headers to the tailpipe.
This system is built by Magnaflow and developed by BimmerWorld specifically for the SpecE46 racing class. It comes with two different center sections, one with a resonator and one with a straight pipe. You can swap the center section if your local track has noise restrictions that prevent running the straight pipe. Both sections produce identical power.
The entire system utilizes V-band clamps at three points for easy removal to effect repairs if need be.
The included Y-pipe bolts directly to the Spec E46 required S52/M52 headers (sold separately here) for a complete bolt-in installation. The Y-pipe also has an additional O2 sensor bung for installation of an optional wide-band oxygen sensor at the merge of the two exhaust banks.
Installation utilizes the stock rubber isolated mounting points. Some adjustments (bending of mounting tabs) may be required to achieve a clean fit without rattles.
While this kit was designed for the Spec E46 (330ci & 330i) it can be installed on any Non-M E46 if the complete SE46 setup is used (headers, y-pipe, exhaust).
This kit eliminates the catalytic converters and is designed for racing applications only and not legal for use on public roads.
