Ive got an 09 XVS650Y, and my muffs come apart where you have pointed out. No need to cut. Im on a lot of Vstar forums, and it seems that this is the going thing now. Be like Nike, and "Just do it"

It won't explode but you will loose half of your torque...
Although the sound will make you think you are going faster than light :)

absolutly right low and mid range torque will drop and top end will increase slightly. also any rejetting will not regain the lost torque. what would get the torque back is larger valves or higher performance cams which aren't available for 650s. i once removed the snorkle in the air filter and the bike ran like crap... no torque. pretty fussy engine if ya ask me, even small mods screw with it. just removing the final baffel cost me some torque, my guess around 10-15 percent which i can live with. because i like the sound and 3 more MPG

RE: Anyone here cut their stock mufflers off?
Id like to rephrase my original title to this post lol...

I didn't realize you can simply unbolt the mufflers. Im looking into slipping some baffles if I do this. I haven't yanked the exhaust apart yet so I don't know what size diameter I can use for a baffle.

I was thinking about trying out these...hell its cheap enough where if it doesn't work no biggie.

i used those in the 70s on my 66 bonniville 650 to get through inspection. as long as the size is smaller than the pipe the'll work, don't need to be a tight fit. just a reminder the cross over pipe and rear header pipe are part of the lower muffler,so you will need to make one cut. you will need to remove the lower muffler mounting bolts and the the two manifold bolts to remove the muffler for cutting

Anyone here cut their stock mufflers off?
So lil update...pulled one of my mufflers and it sounded ehhhh not great. So I slapped it back on and decided to slash cut my exhaust with a sawzall lol. Yeah I had a few beers it did not help that decision making process lol. Anyways the baffles are sticking out like a sore thumb. But I love the slash cut look. So next plan is to get out that baffles, file the ends, and wrap the exhaust.

Any ideas on how to gut the center is appreciated...

http://www.650ccnd.com/slash.htm when i removed the final exhaust pipe on mine i wrapped the muffler with wet rags and burned the pipe as far in as my cutting torch would reach. then i used a dremmel with a worn down cutoff wheel for last inch or so. i have a pic of it on my phone cam but i think it's to compressed to post. with a little grill paint it looks almost stock, but a lot deeper and much louder. it only get obnoxious over half throttle. your final pipe has the epoxy coating on it, meaning it's a catlytic converter muffler. which started in 2005. a torch may not cut through the epoxy but a grinder will. a machine shop will remove it for a little cash if you can't manage it. time is money as they say, and doing it yourself takes a lot of time.

Thanks for the advice and that coating...is me rattle canning the inside to see if it would look less horrible lol. I have access to a plasma cutter and hole saw right now. So one of those two will attempted and could try to find somebody with a torch worst case. My bike is a 1998 unless somebody installed newer pipes.

click the link i put up it shows 1998-2004 mufflers, somebody upgraded your's to the cat ones. maybe the original ones got banged up or something. another thing is strange with your exhaust, i don't see the crossover pipe which all stock 650 exhaust's have. it might be that there were slip on's on it at one time and the stock mufflers were reinstalled

Anyone here cut their stock mufflers off?
So Pauli was on to something... I pulled off one of my heat shields and what I saw made me sick. My exhaust went from big to small back to big. The previous owner/s did a hell of job welding my exhaust with what I'm only assuming could be a car battery and jumper cables. It would be incredibly embarrassing to be seen in public lol.

Spray paint ain't hiding that lol

After a bunch of working back and forth got the baffling out.

I already ordered that black exhaust wrap and this was before I knew about the mess under the chrome. If I wrap my current exhaust it's gonna be thick and thin and thick lol might be pretty ridiculous. I have no experience with this stuff.

So now I have no baffles in the previously semi gutted mufflers. I didn't think it would make that much of a difference. It kinda did and I can say the lack of back pressure is noticeable on decel and I felt a little loss of tq on low/mid. I'm thinking off buying more discreet baffles.

If the previous owner didn't mangle the hell out the exhaust id have something to work with. I would have love to just do a basic wrap from the head-pipe to muffler but like I said it would look pretty stupid I'd imagine. It's a crappy scenario and I think I'm gonna be hunting for some used pipes over the winter.

my stock mufflers are at least two inches higher up than those. i can see why they scrape, on e-bay i'v seen whole systems for under 150.00. if you go that route get one pre 2005 or you'll dealing with those mesh catylists. again! those are not stock pipes because there is no crossover pipe. and they are to low to the ground. i reworked the stock mufflers because they will outlast after market 3to 1 you can shim the jet needle with a #4 washer to get the torque back. they have various stainless sink/tub strainers that are cupped, at home improvement stores. you can modify them into baffles.
