4.4 vs 4.6 vs 4.8 exhaust tube dia

[Themoog2]

Right.. I f you have a 4.6 or a 4.8 can you do me a favour and measure the exhaust pipe outside diameter (as accurately as poss) just behind the rear mufflers please and post your results. I have a plan.. I think.

Does that include interest in after market exhausts as well, I have a Magnaflow fitted.

Mine is an Eisenmann exhaust,cost me (wife actually, birthday pressie) £700 secondhand, each pipe (4) is 83mm OD.

Working from memory now (could be dodgy)
The 4.6is has different size primary pipes (Cat back to resonator) Drivers side 50mm near side 55mm. Central resonator to rear silencers 55mm
The 4.8 from memory is 60mm all the way

hope this hasn't put a crimp in your cunning plan

+1 on details, 50mm passengers side 55mm drivers side to cats, 55 mm out of cats to resonator. There was some dispute as to whether the resonator had x pipes, when mine were removed they definitely did NOT. The Magnaflow does have x pipes. Then 2 small resonators but no back boxes as you can see in the picture above. Sounds more V8 at idle.No drone, I didn’t notice any more interior noise. Only problem I’ve had was due to the fact that there were no joints. Had to cut near cats and fit a join because of removing the rear subframe.
