Complete exhaust system from the downpipe. Un-restricted = no catalysts, resonators, or even a muffler - 3" diameter 304 stainless, a y-pipe, and 4" polished tips. Simple. Light weight. And all of the N55 sound!
This is a complete exhaust system from the downpipe. Photos above show only the rear section.
This exhaust was developed for our race 435i project. Loosely based on the factory M235i Racing exhaust, the rear section eliminates the large factory muffler. It is LOUD and obviously does not have the electronic valves or muffler packing to decrease exhaust volume. But without the large rear muffler this is a lot lighter than the factory system. The rest of the exhaust up to the downpipe is close to stock but with no other resonators or other obstructions.
Easy bolt-on with 4 sections using stainless clamps and factory hangers.
Fits RWD F30 335i and F32 435i models only. Not for xDrive.
Made in USA.
Note: This exhaust system is designed to change the tone and increase the volume of the exhaust. Some states or jurisdictions have strict sound regulations that prohibit any changes to the factory exhaust. It is the responsibility of the vehicle owner to ensure his/her vehicle complies with all federal, state, county, or local regulations. Installation of this exhaust will not increase emissions nor cause a check-engine light or fault codes on a properly maintained vehicle. It was developed to work with all factory emissions controls and equipment.
