OEM M Performance back box with valves and carbon tips need lacquer and some tlc because of scrapes(see pics). Off a M240i but I think it will fit an M140i. Some hairline cracks due to rust on the end that fits to your exhaust see pics. Anyone that can fit an exhaust can cut those out/weld them up + I’ve reduced the price by 50 pounds.
