[Jordan99940]

obviously the difference for those who cannot be bothered to read the links is one is a decat and the other isnt yet the one that is not the decat say its a much better option than the cat (is that only on practicality Basis or is there away the sports cat would be better (if it is even a sports cat))

Better for what?

 

Better for power? negligible

Better for torque? negligible

Better for corroding? definitely

Better for talking about your car down the pub? definitely

better for wasting money? definitely

 

 

This may not be the answer you are looking for.

always count on stu for honesty

 

where would be the best place to source a manifold to fit then?

[Stu]

For what? If you want more power then a new exhaust manifold is the last of your concerns.

[Jordan99940]

well its more the sound for now but the power side of it any extra is a bonus if you get me but dont want to pay and arm and leg for a mega one

[Stu]

Sound? Lose the cat and stuck a cherry bomb on the back if you want a slow noisy car.

[Jordan99940]

id rather have a bigger E-penis by buying one of them manifolds then have a cherry bomb

[Stu]

Well there you go, you've already made your mind up.

[Jordan99940]

what i'm trying to say is i don't like cherry bomb exhaust or most universal ones for that fact i already have a stainless steel cat back system and want something to compliment the rest of the system so any suggestions

 

thanks for your time thou

[Stu]

What do you mean by compliment? You said "sound" above, but tubular manifolds can make your engine sound quieter and raspier, which doesn't sound like what you're after.

 

If you want a manifold for power, then you need the appropriate engine to go with it. Then I would point you to a specialist, like tube torque, tony law, H&S, or someone who could make you a manifold of the right length and diameters for your engine/power requirement.

thanks for the input

You may also loose power from badly designed cheap manifold. I can't comment on their design but the price try are advertised at could mean they arnt great good luck.

I know a lot less about pipes than some others on here, but even I can see how bad both designs are.

The supra has a clever little setup whereby it effectively changes the intake runner length for a given engine speed / throttle position. I think its designed so that torque is not lost in certain circumstances. Could something like this be designed for the zetec or is it not something that every engine can take advantage of?
