Lee McDonald from Australia submits this:
Fitting the stock SV exhaust muffler on stock GS
pipes was a simple cut and weld job. Had to cut the GS pipe about two inches up towards the can from the bend. The SV muffler
pipe was cut about two inches from the muffler itself. In the SV pipe there was another pipe in it. I just grinded off the
two welds from the inside and remove this secondary pipe. I cut two lines of about 15mm long into the Sv pipe so I could clamp
it onto the GS pipe since it is about 4mm smaller in diameter.
Then
I just removed the battery, slid on the SV can over the GS pipe and tack welded it on. Then removed the whole system and welded
it properly, then painted.
Performance wise I would have to say it gave it a better
mid and top range, guessing maybe 2 or 3 hp. The bottom end from 1000 to about 3000 rpm is a bit more sluggish
I think. An ignition advancer or rejetting might fix that.
Sound-wise it is probably a few decibels louder. Certainly not
a barky exhaust and the cops will not pick on people about
it. Worth doing if people have a welder and can get a SV exhaust for free. Since the SV exhaust
has to be cut to fit performance ones on there should be an abundance of free
ones to be found.
These can be found on ebay and in the classified
forum of www.svrider.com .
