Resurrecting a thread here with an exhaust question. I’ve read lots of post here and over at another site with some helpful E39 gents, but exhaust and muffler mods seem to have as many opinions as there are upgrades.

I’m thinking of a simple rear muffler(s) delete and adding glasspacks and 3.5” dual tips. I’m looking for better sound, but not obnoxious for my equal parts style and substance amateur build. So far I can’t find any feedback on glasspacks on the M62.

I appreciate the feedback on the single and dual walled tips that several have post3d about. The 3.5” look super nice on our cars.
