With regards to the manifold, its a lovely piece of kit and makes a very noticable difference! A said in the JMS thread about it, the way the torque is delivered evenly across the rev range and making peak power near on the limiter makes for a rather quick car! A worthwhile modification if your thinking of taking the next step in tuning the engine.
I considered Itbs before putting my car to them for development but seeing as it makes similar power and the a better torque spread throughout the rev range in comparison to a cheap ITB kit and also being cheaper kind of made my mind up. No permanent 'adaptations' on this manifold unlike the ITB kits which leaves the car in a arkward position if ever needing to be put back to standard was a great benefit also.
Are those slipstreams? Anymore pics of the whole car, from that pic they look like the suit it well!
Yeah slipstreams matey, have a look in my project thread as theres a few pictures there.
Cheers
