When I last wrapped my baffles in my Denco chambers I wrapped them with fiberglass insulation and then wrapped loosely with some thin wire. I guess they were a snug fit going back in...
I removed them last night just to check things out (along with checking timing and starting in on syncing carbs, etc.) and found that I could hardly get them out the rear of the pipes. Hammers and punches and chisels all came into play
.
The insulation on the two outside pipes had virtually disintigrated, or it fell apart in the removal process.
The center remained intact but was completely cooked and crusty where in direct contact with the baffle.
All three left all kinds of $hit and debris inside the pipes - some of it oil-soaked but it looks like the insulation was also holding some moisture with rust developing on the inside surfaces of the pipes.
Scraping and scouring only got so much of the burnt-on insulation off and still left lots of clogged perforations in the baffles.
A quick trip to the BBQ and they cleaned right up.
Can anyone shed some light on the proper method of wrapping these things and is there a purpose other than to quieten the exhaust note a bit? The clean baffles slide in and out with no problem. I'm wondering if I overwrapped them, resulting in the grief getting them out. Maybe I shouldn't have held the wrap on with loose wire as is seemed to bind as the flared front end of the baffles tried pulling past it. Any performance differences with or without the wrapping? Is there any down side to not wrapping them?
Thanks for any feedback.
