C-10 Exhaust Questions- AGAIN
« on: February 11, 2019, 03:06:48 am »
New to this style of bike but not at all new to motorcycling.  I've read lots of threads on here regarding a bafflectomy and such.  I used the long rod and BFH approach.  However, its not loud enough for me.  I don't have the inclination to spend anymore on this bike than I need to and buying aftermarket cans are not an option.  With that said, let me state that I have other bikes as well more for bar hopping and the like and are of the chopper and bobber variety.  I also ride for an MC, so this bike does absolutely beautiful on long rides. No fatigue or numbness in the hands.  Just an amazing bike.  But being in a club and riding in formation its hard to have anyone hear me when I rev check to get the attention of the others. As well, they are listening for other bikes for change in engine noise, and distance.  So here is the question.  If I were to say, just remove the cans completely from the union underneath the peg area and run it open like that, is there any adverse affect I would need to be concerned about, loss of back pressure?  Valve burn?  Any insight is greatly appreciated!

Yes, without any back pressure you will do no good except be annoying.
The jetting will be way off and yes you may damage parts.
I never understood the loud pipes thing. I used to ride with a group of cruisers and I stopped because of the annoying open pipe bikes riding in front and behind me. Loud pipes do not save lives as the sticker says, they only aggravate your neighbors. Bafflectomy can be done with the extended hole saw and sound very nice. If you desire to do that I will lend you the hole saw and extension tools if needed.

I remember seeing a post from someone who shortened their OEM cans to get more noise on the cheap.  Maybe that would be an option.

I rode mine around the block without the cans once...it's annoying..but kind of fun.  :motonoises:

Another case of someone buying the wrong bike. If you want to be annoying
trade it in on an HD or give it to someone who will appreciate it for what if
can do and does well.

I think the stock exhaust with the bafflectomy is one of the most pleasing decibel wise and comfortable at fast cruise speeds as any of the aftermarket exhausts i've heard.

You're not revving it enough....  Blip it up to about 9 grand...
4k rpm is for cruisers.   :)

 I ride with a cruiser group occasionally.  Ear plugs and
patience gets me an enjoyable ride every time.  Great folks.

Thankfully, I'm one that is completely happy with the sound of the C10 in stock form.  My wallet is happy about that too.  One less thing to spend money on! :nananana:

I've never even touched 8 grand yet,4-5 grand is just perfect with an occasional sprint up to 7 grand at appropriate times lets me wear my ear buds enjoying my playlist and still stay in tune with the hum of that smooth sounding stock system

I agree I drilled mine with the largest hole saw that would go down the tube and I really like it.

I hit 9k in second gear just this morning.  That is where the fun starts!!!

To the O.P.

I think I remember on this forum or the other one that someone had got some Harley stock take off cans either free or really cheap.
I don't remember if they were that much louder but maybe you could search the forum and find the old thread.

912DMC, It wouldn't hurt to remove the mufflers and try it 1 time to see...
It is EZ to remove the mufflers for a test.

By the way we're not all totally opposed to some additional sound from a Connie.
   {Some of us have aftermarket cans on our bikes as we like the sound}
But we are aware how loud a Connie really is without the mufflers..
You'll be amazed how loud and how much of a Police Magnet the bike will become..
  Makes a Harley with straights seem mild...

If you like the sound, I would recommend extensions to replace the mufflers {to prevent possible engine damage}.
But OMG it's gonna be LOUD!!!

That said, I recently came across an inexpensive muffler option that might accomplish what you want.
Would definitely be louder than mine, but not as loud as open pipes, and cost less than $200.
I'll try to find them and post as a possibility.

Ride safe, Ted

My C10 came with aftermarket slip ons, I love the sound except at about 2-3k rpm .  Like on a back road cruising at 55 in sixth gear, it has an insanely loud echo chamber effect behind the full faring.  Below 2k, people always look to see what sounds so huge, above 5 grand, she becomes a beast most Harley riders try to avoid confronting.  7 to 9.5 grand sounds like  a super modified funny car.  I don't have to use my horn, but I do to be polite. :motonoises:  If it were any louder, it would become painful to my ears for sure, already I'll shift gears to get out of the rumbling echo chamber, deafening range.  But Harley riders hear me coming, and I can rarely hear them.

IF you try it, id suggest a 90 degree turn down tip on the raw pipe.  that last change of direction reduces the 'snap' quite a bit. will still be super loud but will help reduce the backfiring and open shotgun pipe rasp a bit. below is a pic of my buddy mitches bike that another friend built.  its not my style of thing.. but if you notice the exhaust, it has the turndowns at the end  . we added those and it made a huge difference in the sound. (and yes, as you see it is exactly how its ridden sabs the zip tie on the pipe. lol) .  :motonoises:

Cool looking bike!  Never ridden a hard tail before.  Not sure my back could handle it, but I'd do it once anyway! :motonoises:  Before I picked up some Harley mufflers for my GL650, I rode it a few times with nothing but pipes.  OMG! :-\

That's super interesting bike. Not typically my thing but I love the raw steel look, twin Kawi engine (400cc?), and belt drive.

I did come back several times I had issues logging in I apologize.  Well, I did take them off and give it a shot.  Its fu***** loud. I don't mind it however I think the unwanted attention I'll receive will out weigh the benefits.  I'm thinking of going to a 2 into 1 with a two bros exhaust tip.  My buddy has that set up on his and its no where near as loud and sounds very clean.  Thank you to all who replied and if y'all have any more suggestions I'd love to hear em!   :))

I believe you can mount stock Harley mufflers on the C10. I have seen people pick up factory take offs on Craigslist for $50. They are straight through mufflers. Should be loud without attracting too much attention. In my case I am running a set of old Cobra F1's that i picked up for $125 off of COG. Much louder than the baffelectomy but not as loud as the Delkevics with the baffle removed. Good luck and let us know what you end up with.

  Its even odder than that. its a csr305. jockey shift, etc. its weird as hell but rides better than youd think. Guy who built it is an ex F1 fabricator. It was the result of a lot of cheap beer, a german chopper buddy, and a cold night in a heated shop.

Regarding the exhaust: they are stainless hand rails for a bathroom for disabled people, bought from home depot.  :motonoises:  we put them on prior to the DGR in charlotte last year so not to have the issue the OP had talked about, was ear splitting.
