Hello Thor, Which ones did you compare the european one with? I have one like Jdubbya/John and thought I would have to change it back to european stile to get the papers here in switzerland because the installed one is louder. If it is not, all the better.
PAUL --- I'm still looking for an operational, used OEM muffler, p/n 114683, for an '81, US spec, 308 GTSi. Do you have one you want to sell?
