True Helmholtz Technology maximizes performance while reducing drone The BMW 435i is one of the best cars on the road when it comes to driver experience. When road testing, the Thermal R&D team knew that new owners might soon desire a more aggressive, more sophisticated sound that matches the prowess of the BMW coupe. After rigorous testing, a bolt-on rear section exhaust was developed that delivers more powerful sound without adding drone or irritating cabin noise. The goal of the exhaust design was to improve the owner’s overall experience, and the results were better than we could have hoped for. The dual 3.5” polished angle cut tips finish off the high quality look, fitting seamlessly into the signature BMW rear bumper.
