clubman or stainless steel expansion

Hi Chaps,
I have always assumed a clubman would be an all round good exhaust for a standard GP 150 Vijaii MKI..However there are stainless steel expansions exhaust on eBay at similar cost .I have to remove my leaky exhaust to fix a clutch problem so may fit new exhaust....So which would give best performance scoot is Vijaii MkI with the lower final drive 5.65 .( my MkII has the high 4.82.)
KBA clubman or stainless steel expansion?
Thanks
Grandpa
P's on expansion is there a seal between down pipe and expansion chamber do the springs pull it tight as there appears no clamp?
