Question Muffler and soot

Has anyone cut the downward curved tip off the end of their muffler. This would allow the exhaust to go out the back, thus eliminating most of the soot.

As to how this might be done, I was thinking the combined use of a Dremet tool and a hole saw and drill. The Dremel tool would be used to at least start the pilot hole for the hole saw. The hole saw should be slightly smaller than the acutal diameter of the pipe, thus allow one to cut a complete opening. The Dremel tool or a die grinder could be used to smooth it out.

TIA

Before proceeding, check the price of a new exhaust system, it's all one piece.

If you end needing a new pipe, contact me, got one hanging on the wall.

I think one of the coolest design features of the LT is that turned-down exhaust tip. This allows for a much quieter ride when following a fellow LT'er.

The same amount of soot will still go out the back, and a lot more of it will then end up on the back of the bike instead of being directed down.

Remus exhaust is probably your best bet. You might as well go ahead and spend the money because I think you will spend similiar amount of money on new BMW exhaust system.

I have a Remus that exits straight out the back instead of turning down. While I have little to no soot on the pipe, I have to clean the left lower rear quarter of the bike with alcohol from time to time to get all the soot off the bodywork. It doesn't come off completely with soap and water during a regular cleaning. SO in the end it's a trade-off; sooty pipe or sooty bike.

Sure did not affect mine! Just as much soot as before. I don't think there is any reason it should affect it, as our understanding is that the sedondary map selected by cutting the wire only affects ignition timing/fuel mapping on acceleration around 2500-3000 RPM when ambient temps are above 85 deg. F

Only if you never start the bike again afterwards! I cut the wire on my previous LTs and got just as much soot on the pipe after as before.

Also, the "down turned" pipe keeps rain from easily entering the exhaust. That might not be a big deal for you guys who ride in a garage, but for folks around Houston recently, it might be important... also, If you get a bit of snow it might build up in the exhaust and might cause a moisture issue ...

Cool Brown Wire

I still had the same amount of soot with the brown wire cut. A tune up is what got rid of some of the heavy soot that I had....
