when designing a custom exhaust manifold, do you have to take into account the size and length, displacement etc of the standard mainifold, becaus eof back pressures. if each cylinder manifold pipe is a differnt length will this cause the engine to suffer? any info, even the most basic greatfull.

 

Is the engine going to be turbocharged/supercharged?

 

s2 turbo m8

 

Something like this?

 

Nice design mate,

I have a 2.25" stainless magnex Manifold, on my N/A vaux redtop, and all the manifold tubes are the same length, as in the 2 outside go straight down, and the 2 in the middle come forward then go down to equal the length, although sorry cant say that this is the same on most manifolds.

Well ive done the basic info, anyone wanna add a more technical one. lmao

Steve

 

anyone?
