VENOM PRODUCTS
All of the Venom High Flow Cats are constructed from highly polished stainless steel and feature a secondary outer stainless casing that acts as a heat shield. Unlike factory cats which run a ceramic internal substrate, the Venom Cats are constructed with a metal core substrate which offers many advantages.
• Firstly, is its ability to withstand higher operating temperatures, meaning less chance of a substrate meltdown, which is a very important consideration in High Horsepower Turbocharged applications.
• Secondly, ceramic is brittle in nature, and a metallic core sports a much stronger structure making it less prone to cracking on impact. This is important as on a vast majority of vehicles the catalytic converter has a close contact point with the road surface and in some cars it represents the lowest point. This becomes even more of an issue with cars that are running lowered springs. Metal core cats do not crack on impact like their ceramic counterparts and can withstand much more abuse.
• Finally, the Metallic substrate can support higher flowing configurations compared to Ceramic Cats as they are limited to just 400CPSI. This is because the Ceramics strength and integrity is compromised even further with larger spaced holes in the substrate. Our highest flowing 100 CPSI design means that the internal holes of the cats are 4 times the size of most standard or Ceramic High Flow Cats, and in conjunction with a much larger body diameter you can see how they offer uncompromised flow.
The Venom Cats are available in many different sizes and substrate specifications which is why we have split them into 3 different categories, the 400, 450 and 500 Series.
400 SeriesThe 400 Series Cats have a 4” body and are perfect for the majority of street cars whether your running a single cat in a 4 or 6 cylinder application or as a twin configuration in a V8. They are available in 2.25”, 2.5” and 3” inlet/outlet sizes and are available in 100, 200 and 400 CPSI configurations.
2.25" 100, 200 & 400 CPSI - $170 ($330 Twin Package) |

450 SeriesThe 450 Series Cats have a larger 4.5” body and are more suited to Higher HP NA and Turbo/Supercharged applications where extra flow is required. They are available in 3” and 3.5” inlet/outlet sizes and are recommended for cars with single cat systems running 300+rwkw or 350+rwkw in twin cat systems. The 450 Series Cats are available in 100 and 200CPSI configurations.
3" 100 & 200 CPSI - $210 ($400 Twin Package) |

500 SeriesThe 500 Series Cats are our largest and highest flowing catalytic converters sporting a massive 5” body and are suitable for High Horsepower Turbo/Supercharged/NA applications where maximum exhaust flow is needed. They are available in 3”, 3.5” and 4” inlet/outlet sizes and are recommended for power levels greater than 350rwkw for cars with single cat systems and 450+rwkw for cars with twin cat systems. The 500 Series cats are only available with a 100CPSI Metal Substrate.

Comparison between a 2.5" Ceramic High Flow Cat
and the Venom 3" (4" Body) 100 CPSI Metal Core Cat

If we don’t have the cat or size you’re looking for or you need a Catalytic Converter for a custom application, we can custom make any Cat according to the inlet/outlet size, body size, substrate specs and length you’re after!!
All of our Catalytic Converters are also backed by our 1 year Warranty, covering all aspects of the product.
