View Full Version : Exhaust pipe about to break off!

My exhaust has been making funny noises, like an extra higher-pitched buzz in addition to the normal buzz recently. I finally got around to looking at my exhaust pipe this evening, and this is what I found.

This pipe is also loose now, and wobbles side to side:

It hangs so far down now, that it holds the center stand down. As of tonight, I've started scraping the center stand's feet when I make a tight enough turn.
My guess is that the screw/bolt either came out or wasn't replaced after a trip to the shop, and the stresses from hard bumps caused the connecting bracket to break. Further bumps caused the pipe to bend, bringing it lower.

The metal bracket that holds the pipe to the frame is obviously broken, so what is my next step? My stock exhaust isn't the prettiest thing in the world, so it may be time for a new one anyway. I was thinking about the Leo Vince ZX(as it's readily available and seems to be reliable) if ETS couldn't weld the assembly back together. I'm kinda wary about playing w/ roller weights tho, if I get the ZX or some other pipe.

What's next?

Wow, I am always amazed that they stay on being so heavy (14 lb) Leo Vince ZX is half of that including the bracket. How do I know how much it weighs? I just weighed my old one. I have a 03 and did the change a few weeks ago. I got a chrome one because I live on the coast, every thing rust out here with the salt air. Isnít that bracket broken on the engine side and not part of the muffler bracket? If you have the money I would say go for the exhaust and the roller together. The difference is night and day, especially on acceleration. You donít need an Impact wrench, I just used a craftsman wrench I donít know the technical name I think they are called box wrench/close wrench you know the other side of the open wrench. I think it was 1 1/8 inch or and 1 ľ to hold the large nut wile I use a ratchet in the center of it. I think it was a 17 mm the nut came off easy and it was simple to change the rollers. I know in the search they have a walk though.

No, that's def part of what hold the muffler on. The bottom half of that bracket is welded right to the exhaust.

Yeah, that's what I hear, is that part of the performance improvement from a performance pipe is shedding the weight of the stock pipe.

...what gram rollers? As far as I can tell, its a black art, playing w/ rollers and contra springs. :(

6.8, 7, 7.2 grams I would start with 7 grams,you will get 90% of the improvement with out messing with springs. It with will be very different feel to what is on there now,with I think stock is 11 grams .

I was just going to work and I checked to see if the part that was broken is part of the exhaust or engine it is the engine.whet to http://www.easyparts.nl/choosedrawings.php3?brandid=1&modelid=305&submodelindex=du-gr&grouppath=-s757
and they said that it was no longer sold.I think you might not be the only one that it happen to.if you look at your muffler the part that is still on your muffler thats broken screws off. I can see the shinny washer in the middle of it.he is a pic of what the new set will look in chrome.has this happen to any one else?

Oh cripes, it is the engine. Guess its a trip to the welding shop for me.

I would periodically coat your pipe with WD40, just to prevent rust from building up.

Do to the stock or to your performance pipes too (non chrome versions)

Yeah, that rust is mostly from riding through winter, and I haven't gotten around to taking care of post winter stuff. Tho it being in the shop for 2 months for that fuel leak didn't help any. The exhaust gasket is shot, too. Time to do some work!
I'll end up bending the stock exhaust back up and bolting it to the top attachment point so I can get it to the nearest welding shop. I'll let you all know how it goes.

Lucky for me I've got 2 scoots.
