I'm seriously thinking of installing a true dual exhaust out back my 535 but I'm a little concerned about any drone issues.

Thinking of using 4x7 oval Turbo Mufflers at the back and possibly adding a couple resonators in between the cats and the mufflers. Or I might try a pair of 4 inch round mufflers at each end with resonators.

Do you think I'll even need the resonators?

What are your experiences?

Give me your thoughts and ideas.

Thanks
