Hi RWMT, the money was £200 for the manifold from pro-tech of ebay .....really good fit and good quality manifold.
Then I decided against fitting myself...garage only charged £180 to fit and fit the gearbox linkage kit, so all in all not that expensive, and really makes a massive difference to the overall sound of the car, at idle and when driving

I dont feel that the car is much faster...but it does feel more free and revs easier, for sure i would do this mod again and wish i had done this sooner....I had a leaking downpipe for months, but was dreading the hassle...but now im happy it is done
