  1. Really feel the increase in response and torque 5 Star Review

    Posted by on 11th Dec 2015

    I started a my relationship with Fabspeed in April of 2015. I toured their facility and was quite impressed. I purchased their mini max flo exhaust for my 991 GT3. I was able to install it myself in a few hours in my garage with basic tools. I say that because if you’re moderately mechanically inclined and possess basic tools, this can be done in 4 hours give or take. To be honest, this exhaust is not quiet, but it’s a GT3 and if you wanted a quiet car, by a M car or a Benz. I had the stock version, then the Sharkwerks, and now this. I couldn’t be happier. I get tons of compliments and people say it’s sounds like a street bike. It is what I was looking for. I still get goose bumps driving it with windows down. Please keep in mind, that it is not obnoxious or overbearing, it is appropriate for the car. I am highly satisfied. Next I recently went with the ECU tune (stage 2 due to the exhaust set up). I was able to remove the ECU myself which took about 25 mins and the same time to reinstall. It was fairly easy and directions were provided. The car is much more lively. I am very happy that I did this. Overall the drivability is improved through all RPM ranges. You really feel the increase in response and torque through the mid range, 3500-5500 to be precise. My 991 GT3 is my favorite car I have owned thus far and doing these two modifications have made the overall experience in this ownership substantially better and fun. I am very happy with the products and people I have dealt with at Fabspeed.
