Admittedly, my Spyder's juuust a little older'n yours David, but I have cut the end off my muffler & one other (or was it 2?? - I'll hafta check the shed, cos I don't think I ever finished the 3rd one...
) of a similar vintage, gutting what was effectively the last 2/3rds of their innards, and buttoned them all back up again. :thumbup: . It actually worked pretty well in the end; there's no measureable power loss & it frees up the mid range a whole bunch; plus, it does make for a pretty significant weight saving (especially with doing a cat delete too! 
) and the sound output is improved somewhat in 'quality' too, but not so much 'noise', if that makes sense - teamed with a cat delete, once gutted they make a fairly guttural throaty rumble, and that's from the V-Twin engines! But as to it being worthwhile, I don't really think I'd bother doing it again - there's just too many really good value offerings from our sponsors here that there's just no point! :lecturef_smilie:The insides of these OE mufflers are really a pain to strip out - there's basically two pipes snaking back thru the guts from the outlet end; and the inside's broken into three sections by fibre filled dividers/bulkheads with those 2 pipes starting & stopping in each in order to make it work as a muffler. So while once you've got all the covers & trim bits off the outside, it's fairly easy to see where you need to cut the terminating end off, it's a bloody pain to actually get the internals out because of the 2 stupid little pipes going thru each bulkhead & the bulkheads as well as the walls & ends being fibre packed too!! :sour: . The very first third on the muffler's engine end has the larger diameter engine side pipe entering from the engine, while the dividing panel/bulkhead for that section at the other end of it has the first 2 pipes taking gasses out on their way to exiting; then the next third has those 2 pipes coming in one side & another pair going out the other side; with a similar arrangement for the last compartment; and there's no real easy way of getting those bloody dividing panels/bulkheads out without either cutting the whole canister in halves (thru the double & fibre packed walls!
) or using a loooong cold chisel to cut & drive the bugga's out!!! :banghead: And looking back on it now, while trying was an interesting exercise that ended with a reasonable result, it really just isn't worth it!! :lecturef_smilie: . For each one I did, I coulda bought the most expensive replacement option out there and saved myself a fair few hours of painful effort & a few pints of leaked claret coloured bodily fluid, avoided scaring the Child Bride into leaving to spend the week at her sister's, and also saved all the kids in the surrounding few square miles from being exposed to numerous new & colourfully descriptive 'expletive deleted' words that they'd never before heard, and we ALL woulda been better off!
hyea: So while I like the result, it's not something I'd seriously suggest doing.... :dontknow: . Juuust Sayin' :cheers:
