Glad your starting to see sence over the matter.

Exhaust wise alot of people are telling me to remove everything big bore striaght through sort of thing. The problem is that I spent ages reading david vizards books on induction and exhaust design and it just seems like the "powerflow" approach which is something I am 100% against.

Alot of things are contradicting from n/a to turbo like camshaft overlap is completely different, induction design is completely different, inlet is completely different on a diesel from petrol so it might be one of those contradictions but I would rather do some more research before I part with my cash and regret it.

In 3/4 years of owning my punto I had 8 exhaust setups before I was happy, I don't want to make the same mistakes this time.
