This is very much a track/race oriented car.You need to remove the integral pre-catalysers in the OEM headers/manifolds to improve performance and reduce engine-bay heat.On a supercharged install, you need larger-bore manifolds and downpipes to handle the increased gas-flow. Only 2bular offers two different manifold/downpipe designs for the N/A and the Supercharged V6 - two different motors, two different manifold/downpipe combinations.The 2bular 3-1 manifolds for the supercharged V6 feature a stepped-primary design to improve torque throughout the rev range and have the capacity to handle serious increases in power. No other manifold on the market has this feature. Most don't have a merged/TIG-welded 3-1 collector either - some use a pressed design - not the best for optimising gas-flow, minimising turbulence.The manifold collectors are matched to the big-bore downpipes which follow the OEM layout for best clearances and best heat-management.
The 2bular downpipe set for the Exige V6 has a 57mm bore - (up from 51mm on the OEM designs) to handle the increased gas-flow/performance. There's a lot of potential in the V6 supercharged motor and you need these big-bore downpipes matched to the 2bular 3-1 stepped-primary manifolds if you're looking for best power and torque.
The downpipe bore after the collector and into the Cat/De-Cat/System is 70mm - not 63.5 mm! - you need that bigger-bore for best performance.
IF YOU'RE RUNNING A 63.5mm SYSTEM ON YOUR CAR, YOU'RE LOSING POWER!
Plug-and-play wiring extensions for the re-positioned Lambda sensors and all necessary gaskets/fitting kits are supplied with your exhaust.
