Question on De-baffling the pipes on a Voyager

[Bubba in TX]

Where is Gadgets page??? How about a link..... some of us are forum challenged... or search well....

GUTTING 1600 MUFFLERS, the pic is identical to our 1700 mufflers EXCEPT our mufflers have 2 baffles to remove from the rear, NOT 3.

Actually that is funny....... the same but different.... I heard that a lot from my troops when I was in the AF......

I'm kinda curious how it would sound, too, compared to stock. I don't really want mine any louder, but would like more of a low tone rumble.

I drilled out the 2 back plates on mine. In order to drill out the front plates, the mufflers have to come off. Not a problem on the right pipe, but you would have to cut the crossover pipe off the left one, drill the plate, and weld it back on. That's why I just drilled the back 2 plates. Sprayed some WD-40 on the hole saw and it chewed right through. It does sound a little better, but I still want to change out the mufflers.

With a longer extension you can do all 3. That’s what I did. No need to cut and weld.

Yes, but you would have to bore through and destroy the catalytic material to do it as you propose. Some may wish to leave it in place for the environmental benefits and sound dampening effects it provides.

Okay... I drilled out both of the rear baffle plates on each of the mufflers. I had to buy another 12" arbor extension because I was bottoming out the drill trying to reach the second plate with only one.

Question: Has anyone that has done this experienced a chirping sound on final decel when you roll off the throttle? 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.

Havent heard that sound on mine but i have also removed the baffle on the engine side of the muffler.

Did you remove all the pieces? If the chirping is from the engine/mufflers it should do it whether you are moving or not.

Normally a chirping on decel is the belt.

What I'm hearing seems to be coming from the pipes, not the belt. I've heard the noise the belt makes. Mine did it before I had the shop loosen it a bit on the 600 mile tune-up.

I'm curious if somehow the vibration of me drilling the baffles loosened a mounting point somewhere. I'm going to take a closer look at it tomorrow to see where all the mounting points are on the exhaust.
