Anyone done it without making the original pipes rust? I think that cutting them at the weld and pulling out the packing/baffle and welding it back on then getting chromed again would work but sounds expensive.

I would just go and buy a loud set on silencers.

That way, when you get bored of the noise (if you ever do) or you sell the bike, you can put the originals back on.

I have some loud ones on mine and I never tire of the melody they play - especially on the over-run - they pop and burble a little bit.

However, not sure what the neighbours think - not that anyone has complained. ;)

The last time I was closely looked at by the 'Rozzers', they just smiled and laughed.  They were obviously after a speeding/screaming 4 cylinder machines with dayglow riders.

I try my best, but I am obviously not dangerous enough these days!

i have and your right about them rusting again. the only time i hade them not rust i had them dipped with an industrial chrome and not a show chrome.

i ran mine with a couple sets of cans, the first ones where some cheap emgo mini mufflers, basically they are nothing but glass packs and dont drop the tone much, i ran also with just a straight pipe exhaust and ours bikes do have a good loud bark to them (my wife said it sounded like a harley ;D) now i have the tuneable supertrapps. i like them because i can make them free flowing or restrict them down, they are not as quiet as the stockers but enough to keeps johnny law from looking at me to close. really cool thing is when i go to track day i ride up pull ou the disc's and ride

Be aware that cities and subdivisions across the country have enacted or are considering legislation to restrict motorcycles (or ban them entirely!) due to concerns non-motorcyclists have about noise.

It doesn't take many "loud" bikes to bring the wrath of the activists down on the majority of us with legal exhausts.......  :-/

Are load exhausts not causing less torque - ?

If you want something just a bit throatier than stock the MAC replacement mufflers sound nice and the price isn't that bad.  If your current mufflers are in real nice shape then you could probably e-Bay them for most of what a pair of MACs will set you back.  Our 1980 had MACs on it when we got it but I bought a pair of excellent used ones (year old/low mileage) for my '81 R100 off e-Bay for $125.

let the engine breathe, free air flow in and free exhaust out will produce more horsepower. there is some mid range stumble but there are gains in the low and uppers

I have heard of folks using a really long drill bit or extension adapter [think cable TV installer type stuff] to drill out the restriction plate at the inner end of the baffle. Take a long dowel or some such and poke it in there, you'll feel the plate just before the point where the silencer changes angle. I do have a 3' bit but once it is done you cant turn back and new silencers can be costly. If your trapped inside and have a lot of time to read there is a rambling article on the subject which also makes brief mention of torque / noise as a matter of the writers opinion. http://tinyurl.com/2kvjjo
