Replaces the factory rear muffler with a lightweight valved high-performance exhaust system for increased performance and adjustable sports car sound.
We had a customer request an even more aggressive sound from his Maxflo Exhaust System with the ability to quiet it back down at the press of a button. It sounded like a great idea, and it sounded even better once it hit the streets. Now we'd like to offer it you. Our Valvetronic Exhaust System offers the same sophisticated tone that our Maxflo systems are known for with valve closed, but once it's open you'll unleash the full unmuffled roar of the 328's 3.2L heart. Two fantastic tones in one exhaust.
It sounds amazing. I have a key fob to open or close at will. The sound when closed is a little louder than stock and no drone. When open it is straight through and has a nice wail with burble when off the gas. It is the best of both worlds loud when you want if and back to normal when you want to talk or just cruise.
