Has anyone tried them?

I ran them on a stock 502 and a 1000hp blown 509. they work as advertised 7- 10 dbl on a radio shack meter. To the ear they knock it down to a tolerable level.

P.S. with about a 200 rpm on the 502 and no loss on the blower motor

ok not to keep loading up post. I have a set weld in a 4" tube if you want them PM me

I have a set I tried them on a 454 with headers and they tone the sound done a little. my wife didn't notice the exhaust was more quiet, but all my friends said you could not hear me coming. I took them back out I like the noise also I had no change in performance.

Mike, are they model 61-100 ?

no the 61-101

Sorry Mike, I need the ones that slide inside the tips.Thanks any way.

No prob. They are just sitting here collecting dust. Just thought if you could use them. I don’t think they could be pulled from the tubes to easy even though they are just welded in.

PS. ever get up here to northern IL on the Chain o lakes?

Mike

Haven't been up to the chain yet.I saw some info at the boat show,and hope to make it up this summer.
