My 998S MON (EU spec, deep sump) is fitted with carbon Termignoni's 54mm full system (with the correct ECU) from the showroom (so said the seller). Time has long taken its toll on the shine of the carbon material and I am not so confident in having them professionally clear coated over.

So, if any of you happen to have a pair of titanium Termignoni 54mm end pipes, either new (you never know) or in good used nick, more than happy to discuss taking them off you.
