Fabspeed Sport Cats for Chevrolet Corvette C8 2020-2021

Descriptions:

The 2020 Chevrolet Corvette C8 6.2L LT2 V8 is a true enthusiast car and it dramatically benefits from a Fabspeed Motorsport Sport Catalytic converters. You’ll appreciate the more aggressive exhaust note and significant horsepower increase.

These sport cats feature German made HJS 200 cell EURO 6 EC certified compliant tri-metallic catalytic converters. We use enlarged piping from the engine side to the cat, and from the cat to the rest of the exhaust. These are the largest and highest flowing catalytic converters you can fit on the 2020+ Corvette C8. Larger catalytic converters are better because they allow for more exhaust flow and the increased catalysts surface area allows for better exhaust gas filtering which means emissions compliance and will NOT trigger a check engine light. Our Sport Cats are a direct bolt-on replacement for the factory C8 catalytic converters.

Sound:

These Sport Cats will help bring out the signature lopey American V8 sound from your LT2 engine. Check out our videos below to hear for yourself! Designed in collaboration and partnership with HJS Germany Emissions technology Fabspeed is HJS Germany's official partner for Corvette C8 licensed systems.

Power:

We dyno tested these Sport Cats on a Z51 package C8 that had the NPP valved exhaust. At the wheels we gained 6 HP and 6 ft/lbs TQ at the peak and curve gains as much as 9 hp and 9ft/lbs of TQ over the stock catalytic converters. Both dyno runs were done with the valves open on the NPP exhaust.

The new 2020 C8 Corvette is a modern marvel of engineering. It’s mid engined design is a first for the Corvette, but here at Fabspeed Motorsport USA we’re no stranger to mid engined cars. One potential engineering hurdle introduced by a mid engined layout is cooling and some have speculated that an aftermarket exhaust system for the C8 would have to include heat shielding to protect engine bay components. Here at Fabspeed, we strive to provide our customers with the best possible product. That means it needs to meet or exceed OE reliability and performance. So the Fabspeed Engineering Team conducted extensive heat testing of the critical areas in the C8 engine bay.

The goal was to accurately measure the maximum surface temperatures reached in multiple areas. This was achieved by applying temperature test labels together in groups of four in specific numbered locations in the space occupied by the OEM muffler. The test vehicle was a 2020 C8 Corvette Z51 package with NPP exhaust. A total of 16 locations were chosen for the test (See Figures 3 - 6 below). Note: The temperature labels are adhesive backed and operate by turning black once their specified temperature threshold has been exceeded, they are non reversible. These test labels are the most accurate way of determining surface temperature.

Once the temperature labels were applied and the exhaust components installed, the rear of the car was fully assembled (bumper cover, wheel well liners, splash shield) and ran through this test process:

• 1. A 15-20 minute spirited road test.
• 2. 5 Dyno pulls in 4th gear
• 3. 5 minutes at 4k RPM on the dyno (until fluid temperatures reached a critical point)

To establish a baseline, the OEM muffler with OEM heat shielding was installed and ran through the 3 test steps above. The rear of the car was dis-assembled and the maximum temperature results from each area were recorded in the “OEM Muffler” column in Table 1 below. The Fabspeed Supersport X-Pipe with Fabspeed heat shielding (See Figures 1 + 2 above) was then installed, the rear of the car was fully assembled and ran through the same 3 steps listed above. The rear of the car was again dis-assembled and the maximum temperature from each area was recorded in the “Fabspeed X-Pipe” column in Table 1.

The results of our heat testing shows that the Fabspeed Supersport X-Pipe heat signature was exactly the same as the OEM muffler in all 16 test locations. That means that our Supersport X-Pipe and Valvetronic Maxflo Exhaust (which shares a similar design and the same heat shielding) meet OE radiant heat levels and will provide the same reliability and heat control as the stock exhaust system. There will be absolutely no heat related problems when installing the Fabspeed Supersport X-Pipe or Valvetronic Maxflo Exhaust System on the C8 Corvette.

Why We Choose HJS Catalytic Converters:

HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.
