I have a two sets of two (4) total they are mint I used them about 6 mos.

Was thinking about selling them but I dont know how much to ask? I see them range in price from $150ea up to $1000ea.

4" x 12" Stainless steel "corkscrew" silencer. No print or numbers that I can see anyway.

Really nothing? just scarp them

They are probably older Corsa inline mufflers.
The problem is they won't fit most applications with long risers.

they look like gil's..

Thanks for the info!! The boat they came off had Gil tips so most likely thats what they are.

What should I ask for these?? or maybe Ebay them would be the best bet.
