Wrapping baffles....anyone done this?

[Swartzy]

Hi gang,

I have a set of 6x6 cobras (actually 2 sets).  A couple years ago, I tried removing my baffles to wrap them in fiberglass and reinsert.  To no avail, they would not come out.  So, last year a buddy gave me a set, albeit they needed serious cleaning and polishing.  Now that I have them looking great and the baffles DO come out of this set, I was considering wrapping those baffles and inserting them...then swapping out my set for these.

Has anyone wrapped their baffles?  What I wish to achieve is "lessen" the noise.  I always were a helmet and at times, dependent on which way the wind if blowing, it can be quite deafening.  The overall drone for many miles makes me want to put stockers on.  On trips, Lori & I typically wear ear plugs as our helmets are rigged with "Edsets" as we communicate with one another.

So, big question is....has anyone done this?  Is it worth the effort?

All help is greatly appreciated.

Thanks

I used fiberglass like you would buy to put a patch on your boat.  It comes in a sheet and you can cut it to fit with scissors.  I used enough to go around the baffle a couple of times and installed it between the parts that contact the inside of the pipe.  I used stainless steel wire wrapped around the fiberglass to hold it on.

Thanks Thunderbolt!  Did it affect performance (as in needing to adjust carbs or anything?)

I wrapped each baffle with 2 stainless steel scouring pads
wrapped with wire
attached a freeze plug onto the end of the baffle with a 3/4 inch hole drilled in it.

No loss in power (1/2" hole had loss of power), it works great!!!

of course nothing scientific here.

Thanks!  This is very helpful....I think I'll give it a shot!

Are you saying that you stuck a freeze plug into the opening at the rear of the baffles and just drilled a hole in the plug?

Yep, I sized it to fit over tube of the exhaust end of the baffle. That tube was about 1 1/4?
By drilling the 3/4" hole (same size as the piggy), I know that I have not exceeded the OEM exhaust back pressure. I did try 1/2" for grins and giggles, but that was too much and a corresponding power decrease.
This step decreased the volume another step beyond wrapping the baffles.
It made enough difference that I kept the 6 pak, otherwise I would have been shopping for an OEM replacement.
