Quick phase-based exhaust question...

[EngineerD]

Am I right in thinking that the only difference between Ph1 and Ph2 exhausts is the length of the middle section - i.e. a Phase 2 catback exhaust would fit a Phase 1 fine and vise versa, and that it would only be a problem if I wanted to mix Phase 1 and 2 mid section and backbox?

Cheers

not sure exactly but iv'e seen a little stub that come with some exhausts that makes up the difference at the cat join

some phs1 had a single sensor cat some had 2 sensor cats which are longer in length (hence shorter centre)

twin sensor cat is identical in length to the phs2

Yeah it's the cat thats confusing me, it's got a sports cat on it and custom exhaust so it's hard to tell what to change it with (way too loud!). I'll look for the lambda sensors, if it has 2 when it must be longer size hopefully!
