Fister Install on 991.1 3.4L Base
I recently replaced my side mufflers with Fister mufflers from FD Motorsports. There was aa 6 week wait but easy install, except for moving the damping pieces and installing retaining bar from the original mufflers to the Fister. The damping pieces look like steel wool donuts, the difficult part for me was getting the retaining rod pushed thru the damping pieces. 2 mounts per muffler and one of the 4 kicked my ***. Fister mufflers were the only aftermarket exhaust that allowed me to retain the base model exhaust tips and didn't require some type of vacuum valve retrofit. Fister is not an aggressive sounding exhaust, deeper and more authoritative then stock, but not intrusive and no drone at highway speed.
Fister on the left, stock on the right
damping pieces and retaining rod being moved over
had trouble on one of the mufflers getting the retaining rod pressed through the damping pieces
some individuals replace the side mufflers without removing the bumper or the wheels, for me it was much better to remove both for ease of access
removing retaining pin and damping pieces from original muffler to put on the Fister muffler

Very nice. Gopd job.
I just added a set of small resonators to my system.
So I now have AWE x-pipe with small resonators and fister mufflers.
Althought it took down the overall volume a touch, it did take out allot of raspiness. So I'm happy overall.
