Top Gear BMW Z4 (E89) 3.0t Valvetronic Cat Back Exhaust System

This is the electronic valved exhaust system for the BMW Z4 E89, built with our valved technology. The part consists of 100% stainless steel, direct fit tubing, and a sports silencer. This exhaust is also Valvetronic, meaning the silencer has been built with two different flow paths, depending on whether the valves are open or shut. With the valves shut, the exhaust is sportier but only a little louder than OEM while with the press of a key fob the valves open and the tone becomes even louder and sportier! The product is lifetime guaranteed.

This unique exhaust configures a dual-tone setup controlled by a key fob which you can switch on the fly, changing from an aggressive sports note ideal for the open road to a tamer, spouse, and inner city-friendly note with the valves closed. The system comes as pictured and includes 2 valved chambered rear silencers, 2 valves, a valve controller, and high-quality carbon-fibre tailpipes. The exhaust system is fully mandrel bent and TIG welded in order to provide optimal gas flows and increase the performance of the vehicle. The exhaust is priced competitively, sounds fantastic, and is the only bolt-on exhaust replacement you will ever need with our Topgear lifetime guarantee.
