  1. Perfect fit, improved performance 5 Star Review

    Posted by on 27th Jun 2018

    Firstly, the product is well designed and manufactured. It literally bolted into place on my 83 Porsche 911 as if it was OEM. But the best part is, my gas mileage improved by almost 2MPH and I feel a bit more power. I don't hesitate to recommend FabSpeed!


  2. Perfect fit on a 1977 Carrera 3.0 (Euro)! 5 Star Review

    Very nice product, solid workmanship, perfect fit and noticeable performance improvement. Totally recommend this product!


  3. A performance boost with enough "growl" to get you some attention... 5 Star Review

    Posted by on 24th Aug 2016

    I installed both the Euro cat bypass and muffler bypass on my 1987 Porsche Carrera. As a retired engineer I am probably overly "pickey", but the quality of construction is evident from the moment you open the box. The installation went perfectly with the exception of having to slightly enlarge the gasket holes (not made by Fabspeed) and the results were wonderful. I am running this with a Steve Wong chip, and he has a dyno chart for a similar setup on his website, claiming 246 hp at he flywheel. My 0-60 times have definately improved. I would recommend this to anyone desiring better sound and more power from one of our beloved "airheads".
