We're currently working to get more reviews for this product. In the meantime, please take a look at our reviews from other platforms.
Firstly, I want to start off by complimenting the customer service I received from Fabspeed. I worked with Gary from the beginning and he was nothing but helpful, answering all of my questions and helping me understand exactly what I wanted for my car. Once I picked out what I wanted, the ordering process was easy and the package came FAST! Install was easy and the end results were AMAZING. Simply installing their headers took my car from sounding cool to COOL!! I get so many compliments on how the car sounds and everyone is blown away to learn that I only installed headers with no tune. I could not be happier with the result, especially at a relatively low cost. THANK YOU FABSPEED!! Can't wait to work with this company again in the future.
Very special thank you to DJ at Fabspeed. DJ answered my call late in the business day. We chatted about exhaust options available for my air cooled Porsche. He was very patient and knowledgeable. I told him I'd call the next day to follow up as I wanted to do more research on their products. I call the next day, speak to DJ, and settle on several performance parts for my Porsche. Best part, all items were in stock and able to be picked up since I'm local to their shop. I arrive at the shop at the agreed upon time. Items were already packaged and ready for pick up. The cherry on top was an offer from DJ to tour the shop and see "where the magic happens." I really appreciated this and enjoyed hearing about how Fabspeed started and where it's headed. Now that I'm part of their community, I'm looking forward to attending their open houses. I will be back in the future. Fabspeed is more than a "shop." They want to build lasting relationships with their clients while remaining on the cutting edge of product development. Kudos to the entire team.
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.
Fabspeed earned these 5 stars. They design and deliver amazing products. They also stand behind their products. I purchased their Porsche 981 X-pipes as well as their proprietary tune. The XperTune made an immediate difference in my base Boxster (2.7 H6). It’s well worth the price in my opinion. The car is so much more fun to drive now! My Fabspeed purchases exceeded my expectations. Joe and Justin made the tune upgrade process seamless and their customer experience and support are industry leading. Fabspeed is the only business I’ll return to for my Porsche needs if I can help it.
