One thing I forgot... moving the mufflers around a lot could have loosened your muffler gaskets as they are somewhat fragile. But when my Venture gaskets made noise it was like a chirp that moaned on a violin string.

Try tightening the gaskets some. Also check the exhaust gaskets at the heads. Those copper gaskets can leak also when disturbed.

Please forgive my ignorance, but I've never removed a set of OEM pipes from a bike. Can you tell me what gaskets you are referring to and where I can locate them?

When I roll on the throttle standing beside the bike, I hear some strange chirping like sound just as the pipes settle down back to idle. For the life of me, I can't tell if this sound is coming from the pipes themselves or I have a mount rattling somewhere near the rear of the bike. Never heard this sound before drilling out the baffle plates.
Did'nt leave any metal in the pipes?

Gaskets are where the mufflers join the header pipes

Both the rear baffles came out in the hole saw. The baffles right behind the cats did not. This is typical from what I understand from others that have drilled them out.

Still considering debaffling the Nomad, have found a diagram of the mufflers, will try & put it up her, bear with me, but am wondering about taking out the cats as well.
Will there be any problems, will I need to get a fuel procesor, not interested in these if not needed.
Thanks in advancer

Question on De-baffling the pipes on a Voyager

FammdwMike, did you isolate that chirpping sound? Just had a thought. On my brother-in-las 1100 V-Star with open shotgun pipes, I would hear a low wistle when he was off the throttle at certain speeds. Have heard it on my 800 classic also a time or to. I beleive it the air going through the open pipes, a side effect of less restriction maybe. Almost like a low pressure air line that is open. Any thoughts?

Never did figure out exactly what it was. Got a great deal on a used set of V&Hs. Put those pipes on - problem solved.

I'll say this about debaffled pipes... There is definately an improvement in sound over stock, but it does not hold a candle to the low rumble and tone of aftermarket slip-ons. I'm glad I made the investment in the V&H pipes.

This thread is bullshit. It wouldn't have been hard to post a few pics. All you find on YouTube is 900 and 1600 videos. So know I have a worthless exhaust because I did it the way they did. The original threads don't say removing the baffle plates. It says removing the baffles. There is a big difference in those 2 statements. I have been working for 6 hours to get these baffles out and now I see that no one is actually removing the baffles. Guess I'll drive my truck for a few months till I can get some pipes.

Just one more exhaust hypothosis

Please know that I'm as cheap as the come(I rode a KLR for ten years) so here's my question:

If you debaffle the stock pipe do you open it up enough to have enough flow to remove the left side pipe? Then I could have my 2-1 pipe without the cost. Just a thought.

thanks in advance for your consideration!!
