Exhaust Question

[daftada]

Does anyone know, are the exhaust systems the same/interchangble from the cats back on the 4.5, 4.2 and the SS6? Thanks inadvance.

No, the cats are different lengths on the 4.2 and 4.5 so the intermediate pipes are different. The S6 has different length intermediate pipes to the 4.2 but I am not sure if it is the same as the 4.5

I have an S6 back box on my 4.2 and I think the inlet pipes were a bit further apart. I know I had to fiddle around to use the crank in the intermediate pipe to make up the difference as well as a spacer tube to extend the intermediate pipes.
