I've used Dinan products for over 20 years. My current M3 had almost every Dinan mod added the day the car hit the dealer 3 years ago. I am extremely please the performance and sound of their mods. The exhaust sound is to die for. I get compliments almost every day, with absolutely no drone.

As a matter of fact I have not had a single issue since the day I got the car, and just bought it from BMW leasing to keep forever.

Their warranty adds some comfort, but I can say Steve Dinan doesn't put a product on the market unless it's been thoroughly tested over several months. Consequently why they're slow to market.

I won't ever run anyone else's tune but theirs, period!
