As time goes on, emissions restrictions are forcing automobile manufacturers to use smaller and more efficient engines. Cars that used to have six-cylinder engines now have turbocharged four-cylinder engines, with more and more consumers picking the smaller engine over the larger engine. A big concern that many enthusiasts have is how the smaller four-cylinder engine will sound when compared to the six-cylinder of the same car. This exact situation is affecting the BMW G30/G31 520i/530i.
Armytrix decided to show the world just how awesome the 520i and 530i sound with a proper exhaust system. Now that the development is completely finished up, this new Valvetronic exhaust system for the G30/G31 is available for purchase. One of the great things about the Valvetronic system found inside an Armytrix exhaust is the ability to change the volume of your exhaust on the fly. This is great if you don’t want to upset your neighbors, but want to let your exhaust sing out on the road.
Separate from the Valvetronix catback exhaust is a new high-performance downpipe. These are offered without a catalytic converter for maximum performance, but a cat simulator is included to keep your engine light from coming on. With increased horsepower, Valvetronic mufflers, and a lightweight construction, the new Armytrix exhaust is a perfect addition to your 520i/530i.
