Billy Boat or Fister?

[brybart]

I have an opportunity to get a Billy Boat catback system (used) or a modification of my existing muffler by Fister (I live in the bay area so I can drive it over to get modded). I'd appreciate any input by the community.

My buddy has a Fister modded muffler. Sounds awesome and no drone. I have seen people say the BB has a lot of drone, although I have never heard one in person.

Can't speak to a BB cat back exhaust on my Boxster but can on my 03 Carrera. It's definitely a quality piece and the sound is really nice without being obnoxious and no drone.

I've got the Fister mod on my 2000 S along with 2nd cat delete pipes and I love it. No drone and quiet in the cabin with the windows and top up at around 2800-3000 cruising RPM.
