My manifold is blowing, i'm wondering if I should replace it with a standard one or go for a performance one (ie. Lexmaul or similar). The engine is a X14XE, standard except for a panel filter and cat-back exhaust. Is it worth it, would I get any power gain at all with the existing setup? Cheers in advance.

3-4 Bhp get a janspeed one they are mild steel and cheaper, Lexmaul are over priced at £300+, any one heard of BTB exhaust manifolds?

There are good gains to be had from a better manifold, but to really get the best from them, you may have to invest in a programmable chip (such as a Unichip), which will enable you to adjust fuelling and timing

BTB are superb, but not cheap. Quoted me £1000 for a custom built cat-back system (excluding manifold) Needless to say I declined their offer

Lol, ouch. Probably wont be getting a mappable chip, as i'd rather save money for an engine conversion in the future rather than tune my 1.4. However if I can get 3-4 bhp from one I may as well, is this possible on its own?

Also will it fit the existing downpipe?

You'll get gains without an add-on chip - just not as much. As far as I know, the manifold should replace both your existing manifold and downpipe, but best to check with the suppliers about this
