will a stainless/tubular exhaust manifold on a 1.6 zetec make much difference?

in other words is it pointless or not?

 

assuming its a silver top zetec e motor, for the price you'd pay for a new one you could fit a 1.8 or even 2.0 engine.

 

it would if you added throttle bodies on to the list and a couple of longer duration cams..., and maybe a tad more fuel, probably see you at least 50-60 hp gain.. but as said above... fit a 2.0 and you would be up 40hp and have spent alot less. then get with cams and TBs could see you over 200 hp if your lucky LOL
