VENOM EXHAUST WORKS would like to introduce their bolt on range of High Flow Cats to suit High Performance Nissan Vehicles, including the S13, R32 and R33 Skylines and R34 GTR. This Bolt-on cat is our new 400 Series unit which comprises of a 4" Body Cat (3" in/out) with a 100CPSI substrate for uncompromised flow. It will bolt up to all of the above models where the cat is in the factory position with 3" Pipework.
The High Flow Cat on this piece is also our latest design where the metallic substrate, as well as being welded to the casing, is also welded along the inner edges for extra strength, helping to prevent core substrate shift. The piece is also made from 304 Grade Stainless for long lasting durability.
Turbocharged cars are more sensitive to exhaust restrictions than their NA counterparts, so by replacing the factory catalytic converter on your Nissan with a high flow unit, the result will be an increase in power, increased boost pressure and response, as well as giving your car the ability to build more boost earlier in the rev range. The standard catalytic converter is only a 400CPSI design and features a ceramic substrate. Not only can it not flow the necessary amount to support higher power at efficient boost levels, the ceramic substrate is much weaker in design than a metal core cat.
