How can I tell the difference between a Cossie 2WD & 4wd Exhaust system any major differences? I know of a system going but the guy says they are all the same but I am pretty sure they are not. Any way I can tell?

Cheers.

 

they are different as exhaust manifold is not the same so turbo would be in a different position, but do not know how to tell which is which.

 

4x4 echsut downpipe crosses over under the gearbox parallell with the ARB, 2wd one doesn't.

4x4 exhaust will fit a 2wd car if it has a 4x4 manifold, but not the other way round.
