Dinan exhaust sounds from my 2009 BMW 335i.
Dinan is well know for their high quality performance parts for BMW’s. They produces various parts from engine upgrades to suspension upgrades. In addition, they also have engine tuning options which change the ECU variables for more power. This company is unique in the aftermarket world because their parts still support factory BMW warranty. My personal BMW 335i has a handful of Dinan upgrades including a stage 2 ECU flash and suspension. In addition, I have the Dinan axle-back exhaust as well as some cosmetic upgrades. The Dinan exhaust produces a unique sound for the turbo-charged 335i which can be heard in my startup video below!
