The item listed is a premium quality, stainless steel, cat-back Valvetronic full replacement exhaust system for the BMW 4 Series 435i F32. It comes lifetime guaranteed by Top Gear, is professionally mandrel bent and TIG welded out from 304 Grade Stainless Steel in order to provide a more free-flowing system, gaining both power and torque as well as an enhanced sound that is true to the character of the 4 series. The install is complete- featuring the front, centre and rear sections, with sleek chrome finish stainless steel tailpipes. The exhaust includes all relevant fittings required to install it, however, please note that we recommend professional installation.

The sound level this exhaust is configured for is an aggressive, sporty tone without sounding obnoxious. This unique exhaust configures a dual-tone setup controlled by OEM valves 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 electronic valved system for this exhaust is a new state of the art wireless control that even allows hand gestures to open and shut the valves. we are currently in the process of having videos made for this product and they will be added here when possible.
