Fabspeed did everything they could to help me with my exhaust system for my 718 GT4 (Miami Blue baby!). Joe Torchiana was my point of contact and he was exceedingly helpful throughout the whole process. I can’t recommend them more highly. The exhaust sounds great and really opens up the noise given the addition of the GPF on the 718 series. Thanks!
I absolutely love my new X Pipe exhaust for my Porsche Cayman. There was an issue with the new exhaust tips fitting correctly. I contacted Fabspeed and spoke with Ted. Their customer service is beyond anything I have ever experienced before. Ted shipped me a set of new exhaust tips and they fit perfectly. I've gotten many compliments on how they transform the look of the car. I will be ordering a full exhaust sometime next year and am excited it will be from Fabspeed. I recommend this company 12/10.
I purchased the Sport Headers for my Porsche 981 and it was worth every penny! They sound so much better than factory. I noticed improved throttle response and more pull when accelerating. Alec and Jason were my customer service contacts and they were friendly, knowledgeable, and helped me make the best decision for my car. Clean welds, superior craftsmanship, and no CEL. I will definitely be going with Fabspeed again when it comes time to upgrade the exhaust. No regrets and very pleased with my experience.
I have nothing but good stuff to day about working with Fabspeed. From start to finish which includes working with someone on message boards for my M235i, finishing the sale, the product finish, and the east of installation and and final look and sound with my sport cat and muffler delete system with some awesome carbon fiber tips.
Was there for Porsche club event. Staff was incredibly knowledgeable and helpful with my questions about track upgrades for my car. The place was as clean as an operating room. Attention to detail in their engineering and fabrication were impressive. Looking forward to having them do some work for me.
