  1. Nice product 5 Star Review

    Posted by on 5th Sep 2015

    All parts (bolts, nuts, gaskets) included. After cursing heavily during factory cat converter removal, you will want to use anti-seize on the bots/nuts. I combined this with a upgraded Steve Wong DME chip install and the combination provides a noticeable mid-range RPM power/torque boost between 3000-4500 RPM. Very well made piece and deepens the exhaust note with the factory muffler without drone. Overall very satisfied!

  2. quality superb 5 Star Review

    Like a other review I had a problem. The hardest part of the installation was wrenching it out of my sons' grip, By the time I removed the old cat he had it mounted on his wall. After hours of pleading he relented and the installation went without a hitch,
    With stock muffler it has given the car a nice deep tone.

  3. 911 SC Catbypass 5 Star Review

    Posted by on 12th Mar 2014

    I am very upset about the recent purchase of a Fabspeed pre-muffler/cat-bypass pipe. First, and foremost, I was expecting $300 worth of quality and I received $600. I was also expecting a wrestling match with the install and it fit perfectly. The high quality fasteners and copper gaskets were really, really annoying . I will bet that little Fabspeed nameplate is stainless too. Oh, let's talk about weld quality. What's up with no spatter and the beautiful uniform beads? The flanges are disgustingly stout and the overall finish is astounding. As to performance, the 81 SC only sounds better, revs quicker and has more pull. In short, I was hoping for a whole lot less.
    When I scrounge up the cash for my next Fabspeed product, I hope you do a better job of meeting my expectations.
