Im going to fit it myself, as im really not in the mood to pay for a mechanic to spend a day doing it; Ive already had it off once, it was easy to get it off. An axle stand to hold up the center pipe, and the normal jack to raise the front abit.
The stats look quite promising from the site.
just choose alfa romeo, 147 etc and they have the power graphs for a normal 147 and more for different pipe styles

I already have a pro speed 4.5inch back box with limited baffles. And it sounds amazing. Always get people looking in their rear mirrors, to find out what it is behind them.
Its one thing i love, dropping it into third and getting on some B roads, roll on the summer.
