So as previously stated, cat back can be either from the downpipes or the middle cats.
No wonder our V8’s sound like a sick mosquito

So the secondary cats and resonator have been removed. The beast has awoken, so pleased i didn't go the downpipe replacement route first because the sound is just right and ive got pops and bangs to go with it.
Three hour job in total to drop the exhaust to weld the tops of straights.
As you can see, in the EU we have secondary cats just in front of the resonator. I stall have the OPF's and cats on the downpipe so i hope it wont fail emissions or locate a friendly tester
