On the german ebay edition I bid 75 Euro on an original 328 exhaust, and surprisingly i won it, for 72 Euro. http://cgi.ebay.nl/ws/eBayISAPI.dll?ViewItem&item=2440227860&category=28638&rd=1 I have 2 good original exhausts now and I intend to modify one to get some more sound from it. Has anybody done this before? I'm thinking of cutting of the double 1 in 2 endpipes form the 328 exhaust and fit "megaphones" single endpipes, they were an option on the GTO (see picture). I think this will already make an improvement in sound, as the original twin pipes have some sort of absorber/damping material in them. If I want it real loud, I could open up the silencer and replace the perforated pipes inside (I suppose they are there) with closed pipes. Does anybody know how the silencer looks like from the inside, how the pipes run? Has anybody changed a damper before? Anybody has tips? Thanks, Bert.
