V&H slip-ons

Vance & Hines SS2r slip-on cans. Stainless end caps with aluminum oval canisters. They are the glass-pack type, so you can "adjust" sound and backpressure. I use fiberglass cloth. I pack the outlet half. really tight and leave in inlet half open.

I got these in pretty rough shape and spent some hours cleaning them up. Started with 800 grit, then 1000,2000. Final polish was with Mothers' aluminum polish and a felt disk on my grinder. I think they came out pretty well. I replaced all the rivets and screws. I was able to find the SS screws at a local nut and bolt store.

They are almost identical to what I have on my 900F; the only difference is that these have the mount attachment on the top, so much better for fitting on the GS500F.


Install complete. We were not able to copy the original angle of the stock exhaust due to the length of the V&H can and the location of its mount without modifications to the frame; and I like all mods to be reversible. (I still have the stock exhaust system that came with the bike)

It's hard to beat the upswept look of the original; but on the other hand, it gives the bike a longer stretched out profile.

Once again Domingo comes through with some nice welding: steel to stainless to steel. Haven't decided if I'll paint it or not.

In order to use the original mounting point he made some bends in this thick aluminum dog-bone, sourced from spare parts from my R6 shock install. I'll probably paint this part black, and find some nicer looking fasteners.

I've been riding around without my side fairings for a while now. I sourced an NOS K&N drop-in complete with instructions and restrictor from a Canadian shop (about half price delivered). So I'll need to do some re-jetting soon. But the bike runs well with this can and the stock air filter. The off-idle power gap that always bothered me is almost completely eliminated, might be the added length giving a bit more low-end torque. I'm hopeful that I can tune it out completely.



How's the sound? The V&H full system for the GS500 sounds like an unbearably lowed and angry lawnmower. Was not my cup of tea with a tone higher pitched than stock.


Armandorf, yeah he's pretty good. He knows his stuff and I was impressed that he can join stainless to regular steel so well, as some people struggle with that. I was talking to him today and showed him a pic...he said to come by when he's not so busy and he'll try and correct the angle to match the angle of the rear fairing, more like the original. I don't see it as a huge problem, but he offered to do it for no charge because he wants it to look good--cool guy.

Bluesmudge, I think the full system V&H had a round steel can with a mechanical baffle. This is an aluminum oval glass-pack. There is no baffle or obstruction, just a straight-thru perforated tube wrapped in fiberglass insulation to absorb the high frequencies. Back in the day when they were new, this was a top-of-line product, an expensive upgrade for the Ducati's and other high-end sport bikes.

I had it half-wrapped which worked very well for my other bike; that is I wrap the output side of the tube, first with layers of fiberglass cloth and then with a thicker layer of the regular non-woven fiberglass--the inlet side is unwrapped to the halfway point so you get an expansion pulse using the open half as a resonator. Again this sounds great on the 4-cylinder Honda but I felt it was too loud and percussive on the GS--even though it's a similar displacement per muffler.

Riding home I felt conspicuously loud, it's a really "punchy" sound. So the next day I pulled the baffle tube and packed the inlet side with a copious amount of Rockwool. I don't know why the sound is so different between the two bikes: 243.5cc vs 225cc per cylinder, both with 9:1 compression. I came to the conclusion that 2 large valves vs 4 smaller valves must have something to do with it.

Anyhow here's a short clip. The camera has auto level for audio, I tried to place it in a similar position. I didn't rev too much because I was trying to spare my neighbours, but it's enough to give you an idea. It's definitely sounds louder than stock when riding, but it's mostly a bass-y low-end increase. At about 100km/hr the wind noise in my helmet drowns it out, but when riding at lower speeds where you can hear it has a very satisfying "motorbike" tone...punching it of a corner will make you grin every time :D
