hi all,

First post, been watchng you all for a while soaking up the knowledge . Now I could do with some advice.

I after upgrading my exhaust on my 1.9 cdti (120). I've heard all about the magnex and owerflow and janspeed cat-back systems. What I would like to kow is it possible to get an uprated manifold and cat?

I'm an engineer in the navy and understand the principles of balancing the exhaust flow pressure etc, but does doing this make any difference on my pride and joy and if so where and how much?
