Downward Exhaust

New user so forgive me if this is already covered and I didn't find it on my search.

Is there any reason that the exhaust at the rear of my bike is diverted downward right as it comes out that nice chrome pipe? It is driving me crazy cleaning the black of the otherwise spotless chrome.

My riding partner with a Harley can't believe they aim it downwards right into the pipe.

Is this needed for some reason and is there anything out there to adapt to run straight out?

Don't want my bike louder or anything, just want to keep it as spotless as possible.

Thanks,

Re: Downward Exhaust

It's a feature! The carbon on the chrome is your assurance that the fuel injection mapping is indeed going full rich on startup!


Just wipe it off or better yet just ignore it and ride the socks off it!

Spotless and chrome should be classified as some what Oxymoron.
Go ride the damn bike, collect some splattered bugs ..... get a life and forget about being a clean freak with your LT.

Nah, he's all right. It doesn't become pathological until he starts cleaning and waxing his fuel cell! Then we need to start worrying!

Hey Frank, how's your shiny gas tank looking?

Re: Downward Exhaust

First, to answer your question about the down turn, it most likely was to keep the exhaust noise to a minimum. I put a Remus exhaust on mine for a short time and the noise was disturbing to Ol' What's Her Name. It wasn't really the sound of the exhaust that bothered her (and eventually US), but rather the fact that the exhaust pipe came straight out the back and directly under the left pannier. It seemed to pick up the exhaust note and amplify it through the pannier very similar to banging on an empty 55 gallon barrel with a hammer. Several people have fixed this problem by putting a 4 inch extension on their Remus. Unfortunately for me, I didn't find out about this fix until after I returned mine to stock and got rid of the pipe.

The other added bonus of the down turned pipe is that every time you drive in and out of your garage/parking area you get the floor dusted and the leaves blown off your driveway. The last good reason for the down turn is that when you start your LT after being on the side stand it doesn't blow the oil smoke in your Harley buddies faces, but rather lets it waft gently up to them similar to fog in a Lon Chaney movie.

Now, as to polishing the chrome...I do clean mine from time to time (read here, about three times a year) but my motto is: "If I have time to wash it, I have time to ride it" The road grime, bugs and soot are what distinguish us from our clean freak Harley brothers. Well, that and helmets, appropriate riding gear, gloves with fingers on them, smiles instead of scowls, odometers with more than 4 digits showing, the ability to hear our radios over the din of blaring exhaust pipes, tires with wear on the outer edges too, and......well, you get the picture. I'm envious that you take the time to clean your LT. They're great looking bikes especially when clean but as you spend more time riding you'll find less need to clean because you just won't want to pull yourself off the road that much. Enjoy! and be safe.

BTW, welcome to the forum.

Re: Downward Exhaust

Rumor is it rains and snows occasionally in Germany...and Europe. If the bike should be parked outside.. (I know.. silly) then with the pipe turned down there is less likely to be a problem with precipitation finding it's way into the muffler... then exhaust.. then the rest of the exhaust.. and even into the cylinder with open exhaust valve.. and rust..

Who wants to wax inside the engine?

Re: Downward Exhaust

"Hey Frank, how's your shiny gas tank looking?"

Well, the outside looks real good (click, twitch, click click), but I'm having a biotch of a time getting the inside the way I want (twitch twich, click, twitch). I've purchased an endoscope and dremmel tool to get down inside (click twitch), and am planning to use it to remove the built up carbon deposits inside my exhaust pipe. I th-th-th-think it'll be OK OK OK now (twitch click twitch).
I jus-jus-just h-h-h-hate that (click) exhaust s-s-s-s-tuff on my e-e-e-e-xhau---sssst p-p-pipe (click click click twitch)
Oh fu-fu-fu-fu-fu, screw it, I'm gettin' a Ha-Ha-Harley and pi-pi-pi-pirate suit.

Re: Downward Exhaust

Along the same lines...anyone ever "remedy" this issue by, perhaps, cutting the down-turn and putting a straight extension on the OEM pipe that extends from the factory muffler? If you did, do you have details and a pic?

I would swap a decibel or two if it would mean I wouldn't have to use two different sponges every time I wash the beast and then spend a couple minutes with chrome polish (yeah, I'm "that guy" that likes the chrome to sparkle)

You're supposed to clean it???? I thought that's what the rain was for. Sure don't want to waste valuable riding time with soap and a rag.

Re: Downward Exhaust

Somewhere in the distant past, I was told it was turned downward in order to help meet the then-current Euro noise regs -- the air pulses (sound) dissipates as it reflects off of the pavement across 360 degrees, before it returns back up to where the sound test microphone is located.

It's too hard to tell from that description. What do they taste like? And are they soft or crunchy?

Re: Downward Exhaust

Well, thank you for the replys, it is very entertaining. Bugs are very plentiful up here in Alberta and a guy can waste alot of time attempting to keep it clean. It isn't until you get in the mountains that you are able to ride all day and still see through your windshield.

All the responses as to the downward turn seem to make sense...thank you. I am definitely not interested in making my bike louder. I definitely get the two different rags comment!

Anyway, she is beautiful when she is clean!!!! I promise to ride her even if she is bug covered and dirty but I will still pamper her when I have the time!

Thanks,
Colin

Re: Downward Exhaust

I would rather clean the end of the exhaust occasionally than have to clean the soot off the back of the left side case. If the exhaust was straight, I am sure the airflow around the back of the bike would cause sooting on the lower rear much more than with the turn down, since the LT does put out soot on hard acceleration. And occasionally on start up so I hear.

I don't want to achieve immortality through my work...I want to achieve it through not dying.

Re: Downward Exhaust

With my cleaning supplies, I have a small tube of metal polish and an old sock. Just a dab of polish on the sock, a quick wipe on the end of the Remus pipe and I'm done. I probably do this several times a year after each oil change.
