Default Is an LS exhaust manifold the same length as an SI one?

As the topic says...is a Civic SI stock exhaust manifold/downpipe the same length (to cat/exhaust) the same as an Integra LS?

Im currently running an SI manifold/downpipe/exhaust on my B18B1 motor and the downpipe hits the oil pan, must be a different angle or something...so Im looking to get a stock LS unit.

I believe the b16 has a shorter deck height.. so therefore if u put a b16 header on a b18 series engine it would not clean properly... (to lazy to get the real info) =P

I've heard they are the same, but I don't see how since the b16 is a shorter motor.
