I sold my MaxFlo�s and installed some Fisters with the headers and Cats.

The parts were installed under a previous ownership.

Are your also running Fabspeed headers and x-pipe (w/ cats)?

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hoping to get some info from anyone with experience on Fabspeed parts with 996.
I currently have Fabspeed sports headers, x-pipe with 200 cell cats, and muffler in my '99 996. The parts were installed under a previous ownership. I was hoping to reduce some of the sound and cabin drone (when cruising at around 2-2700 rpm) but not take away much of the performance gains.
I was wondering if anyone else is running this exact setup who thinks they are too loud, and what actions were taken to reduce the sound. Basically, I want to switch some of the parts back to stock but I'm not quite sure which to switch back.
@Imo000
Thanks! Just wanted to note, I have less the aggressive Maxflo performance exhaust, not the Supercups. I'm not sure if that changes your opinion.
Thanks for everyone's input. I will see if switching back to stock mufflers will be enough. If not, I will also switch back to stock cats.
Had the car come with stock exhaust when I got it, I would have definitely gone with a simple Fister exhaust.
That is definitely good to hear. Hopefully that will do the job in my case. I also have the sports headers so I'm not sure if that will keep sound louder than I would like to.
I was running the same set up. Same noise/drone issue. It�s not that they were bad but they were always on. The Fabspeed set up sounds killer on the track.
I sold my MaxFlo�s and installed some Fisters with the headers and Cats. It�s quiet compared to the Fabspeed set up I had but with the Fisters you can make them scream at your leisure.
