Has anyone used these to tone down the side exhaust. I have Sanderson headers and mufflers, and would like to quite them down alittle. I have already repacked my baffles, helped alittle. Any tips would be appreciated.

By alittle, do mean more than the mufflers you already have or alittle from open headers.

I believe they would help a little compared to open headers, but not as much as the typical insert
with packing. Hard to give a good opinion when we don't know what you have for mufflers.

No, I don't have any experience with them.

Seems like I saw a revue somewhere it dropped about 5 dB.

Thanks everyone for the replies, yea I have the 12 " baffles and packing that came in the sanderson pipe turnouts. Just a little too loud and wanted to quiet the exhaust some. By the youtube review, they don't seem to do much.
