Been a regular customer for a while now and I must say that they're the best at what they do! Bought a number of upgrades for my 991.1 911 Turbo from Scott and absolutely love the extra power and sounds! Top notch quality and service, would recommend to anyone looking to upgrade their car at any level of performance.
i have made the installation of the FABSPEED Sport cats and Sport headers on my 2017 Porsche 991.2 Carrera 4 cab at my Porsche Center yesterday and iam very satisfied. Still quiet when the PSE is off and very loud in sport and sport+ mode, i like so much the backfire who are this time stronger and the turbo noise who is more noticeable. Iam very happy of the sound a lot better of the original one, thanks you FABSPEED
I have been using Fabspeed products in my cars. I've tried different things, Resonator bypass X-Pipe, Sports headers and blankets and others on my Ferrari, Audi, Porsche, Maserati, etc.... They are reliable as advertised and have a great customer supporting system available everywhere. I have a great confidence in their products and will continue to use them in future... A reliable company that really follows up with you.
months before i put down my deposit on my custom ordered P car, i already knew which exhaust was going on it. even though there weren't any youtube vids of the system, i relied on the opinion of the Fabspeed employee and other forum members who had the system on their cars to tell me the characteristics of the exhaust. so, when there was a Father's Day sale, i pounced on it and had the exhaust sitting in my living room several weeks before i took delivery of my car. craftsmanship on the macan turbo slip system is flawless. no damage during shipping transit, either. the CF tips look awesome. install, done by a specialty shop near me, was done within 1.5 hours. system sounds exactly how i wanted it to sound; loud, pops, bangs, burbles, etc., etc. i even ordered some extra decals and they were kind enough to not charge me for shipping! now that's customer service.
By far the most professional and experienced when it comes to Exotic Motorsports, Performance and Tuning. I have been to many of their shows, and have had Maserati Tuning done here! Definitely recommended as well as their Exotic Shows are a great fun time for the whole family!
