Drag pipe baffles on a CB?

[ccvsgod]

...opinions and experiences needed!

This is for a Scrambler (CB pipes to either side, not upswept). I have these Shortys on there which I love but are shot baffle-wise and criminally loud. Since I want to keep the Shortys (or maybe not any at all if it works) I'm thinking about drag pipe baffling in the headers. The longer/quiter the better for my purposes, but I have to see how much I could fit before the header starts to bend, probably end up being the 4" ones if the 8" are too long. So...If I adjust for compression changes, what are some thoughts on this, or has anyone here ever gone Full Retard and went there?

My friend and I put the 4 inchers and some little turn outs on his CB350. It's loud but not ear splitting. When he just had the empty turnouts it was obnoxious. I personally like to have a little packing in there to mute the upper harmonics. Gives it a lower note. Then again I'm an audio engineer so I judge everything by tone .

Wow dude, your CL350 looks amazing! This is for a 69 CL450. It looks like an 8" might barely fit. Do you have to drill a screw hole or do they fit in there just by diameter?

I put the 4" ones in the tips on my chopped CL350 exhaust too. It's still loud but much less eardrum shattering. I wanted to mount them in the tip itself rather than in the header so I wrapped it in fiberglass packing first for a more snug fit and lower tone. It seemed to definitely mute it a bit, but not much more. To install them I just drilled a hole in the backside of the tip, ran the bolt through the inside and tightened the nut on the outside.

Thanks man. They went in my friends bike actually and they were snug! No screw needed especially because he put little turnouts on after them.

I've got a XV250 and I want to put turn outs on the pipes but I also want baffles, so from what I understand if you've got the turn outs on the pipes you can't remove the baffles? Also whats a good DIY solution to the baffles since I don't want to spend too much coin on this project.

Cheers

Those baffles are cheap on eBay. They stick in pretty tight on there own from my experience. The turnouts are pretty much just insurance that you won't fire one out.
