Where did I put the plates on the baffles??

I cut the baffles almost in two with a hacksaw and brazed the plate with the holes in it in the slot I cut. I bought the plate with the holes from a metal supply place in town (there is a name for the plate, but I can't think of it now). I put two of the plates in each baffle about a third of the way from each end. Then wrapped the whole thing with the fiberglass packing sheet and held the packing down with wire. It has a real nice sound and not too loud.

It has lasted about 8K miles so far with no problems. My buddy at the bike shop where I got the packing said it will eventually blow out and have to be replaced.

Meet Wall-E.




Simple angle iron from Lowe's, drilled through both sides of the baffle & secured with bolt, nuts & lock washers.




Broke up the sound a bit, but since the baffle walls on HK 3" big straights are solid pipe, wrapping with fiberglass would do no good. Just the one "plate" in each actually toned them down a bit, but I eventually took the plates out and just run with the stock spiral baffles, loud & proud. Really loud.

Re:Loud exhaust 2 Years, 7 Months ago  
I'm running Cobra Boulevard drag pipes with the stock baffles. I've been thinking about quietening mine down a little as well by wrapping the baffles with fiberglass insulation as well. It took me a long time to get my jetting & fuel mixture just right so I don't want to throw it off. My Cobra baffles are straight-through; will wrapping them affect the mixture much?
