Utilizing our two development McLarens, MP4-12C and 570S, we've experimented with many designs. After dozens of hours of testing and engineering, we have been able to craft the highest quality catted downpipes on the market. We are utilizing the bullet proof, high flow 200-cell HJS German Imported HD catalysts that flows 91% to 93% of a straight pipe for most possible power and no check engine light.

HJS Germany manufactures the highest quality catalysts in the world. Fabspeed has incorporated 200 cell-HJS HD catalysts into our latest design to maximize horsepower. Our complete redesign incorporates these high flowing catalysts in conjunction with heat blankets and makes incredible power gains especially when paired with a complete Fabspeed exhaust and ECU Tune package.

 

HEAT BLANKETS:

Included only at Fabspeed Motorsport. Protect your engine components from intense heat with thermal blankets. Keeping heat in the exhaust maintains the maximum velocity of exhaust gasses, allowing the turbos to spool faster while ensuring maximum power is extracted through increased thermodynamic efficiency and flow. Fabspeed thermal blankets are rated to 2200 degrees. T321L Stainless steel mesh over a 321L stainless steel inner liner covering ceramic insulation makes direct contact with the downpipes. The basalt fabric exterior covers sewn with stainless steel mesh covering all edges and high quality stainless steel spring fasteners ensure longevity.

    Joe and Amanda saves a bad situation. My friend is getting his exhaust for his 911. Looking forward to the improved sound and feedback.

    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

    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.

    I purchased an exhaust system from FS over 2 years ago for my 997.2 C2S. The sound was just glorious and I was pleased with the purchase. Unfortunately, last month, a weld broke on one of the mufflers and I needed it repaired. After one phone call, I could tell this company takes customer service seriously. In a world of voice mail and self help, Everyone I spoke with was very professional. In fact, Brian Jamison proactively called me 2 times and sent follow up emails, to keep me updated during the process. Fabspeed completely warranted their work and sent me 2 brand new mufflers with an improved design. (Not only is the engineering more simplistic but the welds and workmanship are gorgeous. They aligned perfectly and went on in minutes.) Very impressed with this company, its people, and it's product.

    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.
