Valvetronic BMW M3 / M4 Equal Length Valved Sport Exhaust System (F80 / F82 / F83)

This full catback is comprised of a 2.75" equal length mid section with an H pipe configuration. After traveling through the H pipe the exhaust is combined into a 3.5-inch axle back. This combination helps smooth the exhaust tones to provide a very enjoyable sound through the entire rev range. When operating with the valves open, the exhaust gases exit unrestricted out of the passenger side exhaust tips. With the valves closed the exhaust passes through our quad chambered muffler and out of the drivers side exhaust tips for a lower volume experience, very well suited to daily driving. This system mounts up to factory mounting points and is a direct bolt-on. No cutting or welding necessary.
