Tip Options


The G30 M550i exhaust ushers in a new era of Dinan exhaust design. To date, Dinan has been synonymous with welded on, thin walled tips and a philosophy of exuding a civilized note when you want, yet a pleasantly aggressive one under hard acceleration. This mantra is maintained, albeit tweaked, with the emergence of mid-pipes and resonator deletes to those who want an even more aggressive sound. Dinan is further extending their offerings with the unique styling of their drastically-transformed tips. The new massive 4" diameter tips on the M550i exhaust are the biggest Dinan has done thus far, in addition to being double walled, the polar opposite of their normal thin-walled style. Perhaps most importantly is that the new tips are clamp-on. In departing from the welded tips of the past, tips can now be easily swapped to new styles, or replaced as the need arises.
