BMW G20/G22/G26 M340i/M440i Valved Sport Exhaust System

The seller answered all my questions about fitment, options (valves, material, etc.) And shipping. The exhaust arrived quickly using the faster shipping method (approx. 10 days). The build quality (stainless steel) is good. All welds appear to have good penetration. Fitment is good. All of the pieces fit together properly and utilize the oem exhaust hangers. It would be worth using some gasket maker/exhaust cement or using a lap joints as there’s likely to be exhaust leaks using the supplied exhaust clamps (this is true for any aftermarket exhaust and not a criticism of the product). Sound is very good. Almost the same noise level as stock with the valves closed and a nice loud sound with the valves open. All the pieces needed to install the new actuator and swap over the oem actuator were included. Absolutely recommend purchasing from this seller.

Besides waiting almost 3 months, my only real complaint was the exhaust arriving dirty in the inlets. The exhaust setup is practically identical to the Valvetronic and sounds tough with my Active Autowerke downpipe. Super happy for a exhaust setup in it's price point. Remote does have limited range to reach the valves in the rear so I learned its best to point the remote closer to the back from the driver seat. Other than that, the thing sounds aggressive and looks amazing aesthetically.
