BMW 335i/435i Valved Catback Exhaust 2012-2016 (N55 F3X) | WSTN Performance

More flow, more sound and more power from the N55 straight six. WSTN Performance valved catback exhaust for the BMW 335i and 435i (F30, F31, F32, F33 and F36, N55 3.0 turbo straight six). It replaces the factory exhaust from behind the downpipe back to the tips with free-flowing stainless steel pipework, a rear muffler with two valves and quad black tips. The result is more flow, a louder and deeper six-cylinder note, and more power through the rev range. Select your car below, enter your VIN, and we double check fitment before your order ships. Why Upgrade? ✓ More Flow: Free-flowing stainless steel pipework replaces the restrictive factory rear section, so there is less in the way of the exhaust gas on its way from the downpipe to the tips. ✓ More Sound: A louder, deeper straight-six note when you are on the throttle and more character when you lift off. The sound the factory system holds back. ✓ More Power: Less restriction behind the turbo lets the N55 breathe easier, for sharper throttle response and more power through the rev range. ✓ Perfect Fit: Use the car selector on this page to confirm your model and year, and enter your VIN so we can double check fitment. If entered, your VIN is submitted with your order at checkout.
