Hey guyz,
it's been a while that I have changed my back exhaust and now I am thinking of changing the whole system.

I have a Civic Coupe 97 LSi (Euro) and been looking on the net for a good manifold to start with. I have seen many diff types and I am not sure which one is the best to choose.

What I have in mind is a 4-1 design. here is a link:

But I have seen dif types like 4-2-1 or 3-2-1 (Y type or something like that). and i don't know which one is the best for performance (and also the sound!)

Wut you suggest guyz?

 

btw sound doesn't matter, 90% of your exhaust tone is going to come from your exhaust piping, muffler, and cat...

the oem style 4-1 manifold is what's called a 'log manifold' bad flow, but popular for turbo applications because it is so compact...

the 4-1 manifold you are looking at isn't bad, but the flow is much better with a 4-2-1 setup... The exhust pressure from the cylinders equalizes itself when it's coming out...

there's no such thing as a 3-2-1 setup unless your running a three cylinder geo metro... lol

the numbers represent how the piping reduces...
4 exhaust cylinders-go into 2 pipes-and then those 2 pipes reduce into one...

 

my first car was a 3-cylinder metro h:

got great gas milage :deek:

 

my friend had one with a 1.6 turbo storm motor in it... lol

it looked like shit, but hauled balls... lol
