i want to run a unsilenced screamer pipe on my s1 with a stage3 t3 and run high boost of around 25psi as my engine is built for this....

whats the best way of doing it?
and would i need a custom manifold?
and did raj at autoflock ever get his kit to work?

i want a naughty sounding car again as my last real toy was a 220bhp+ aspirated cosworth mk2 escort on 48s ect and miss the mental noises lol
