Our valved catback exhaust system for the BMW F30 335 or F32 435i gives you the versatility you want in an exhaust system. Valves open, you can let everyone know you're here - loud pipes save lives, right? Valves closed for when the kids or the dogs are sleeping in the back seat on a long road trip. Our valved catback system functions differently from other alternatives on the market, including the factory system; most of these we've found only utilize one side of the exhaust system for either valve closed or valve open operation. Accordingly, we designed our Turner valved catback to utilize both muffler exits for valve open and valve closed operation. We use beautiful 1.25mm thick, 80mm 304SS pipes with smooth mandrel bends to create our catbacks, ensuring that our systems are as visually appealing as they are audibly. We believe we've done the F30 335i and F32 435i the justice it deserves from an exhaust perspective - your turn to judge!
