For sale is a set of Dinan mufflers (D660-0036-BLK) for the 550i that I bought back in Jan 2020. They are in excellent condition with less than 6K miles . They slip right on without any welding, just a cut of the original exhaust at the “punch mark” is all that’s needed. They work with the stock 550i diffuser or any aftermarket V-style diffuser *.

In terms of sound, these have a mean growl to them when you put your foot down to bring out the V8, but also subtle during cruising speed. They are by far the only 100% drone-free aftermarket option.

Diffuser in pictures is also available for sale in another listing.

Asking $1,300 + shipping. Purchased originally for $2,100, but prices have now shot up to $2,700.

Mufflers will be removed and ready to ship by 12/31. Taking offers now and/or deposits.
