The Dinan 535i exhaust systems

dinan exhaust bmw As a serious BMW Tuner, Dinan’s objective is to offer complete performance solutions for the entire range of BMW models. Dinan’s free flow exhaust for the 335 improves exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be and pleasantly aggressive under harder acceleration.

100% stainless steel construction and exacting specifications ensure that the system fits correctly using the factory hangers and will resist corrosion for years to come. The design reduces overall weight as well and features 3.5” polished stainless tips for a tasteful high performance look.

There are two major areas of the complete exhaust system that are typically tuned for enhanced performance; the exhaust manifold or header and the rear muffler(s). The exhaust manifold’s length, tubing diameter and the manner in which each cylinder is linked to the other is critical when attempting to maximize an engine’s power output. The manifold configuration can be manipulated in order to generate maximum power at low, middle or high rpm, changing the shape of the power curve accordingly.

Naturally some compromise must be accepted when tuning an exhaust manifold for a street-car as the goal is typically to ensure balanced power output at low, middle and high rpm. This is in contrast to a race-engine where the exhaust manifold can be tuned specifically for maximum performance at high rpm. Dinan knows all that and makes lots of reasearch and tuning to achieve best performance from their products.

Founded in 1979, Dinan is well established as North America’s premiere BMW tuner. Dinan develops, manufactures and markets a comprehensive line of high performance products and systems, distributed through a nationwide network of Authorized Dinan BMW Performance Centers that includes select BMW Dealerships and Independent BMW Service/High Performance facilities.
