I have just been to try and fit a new exhaust on my girlfriends 1.8 Astra SXi. It is fitted with a standard Witter tow bar which is in exactly the wrong place for a larger back box to go into. I tried systems from Magnex and Remus but both were bigger than the standard box and neither would fit in with the tow bar frames there.
Anyone know of a manufacturer who make back boxes the same size or smaller than the standard Vauxhall one? Are exhausts likley to fit in with a tow bar? Anyone had this problem?
I'd ask my local Vaux dealership, but they seem clueless about technical issues (they're much happier selling Agilas to the over 70s)
