got 2 pairs of custom marine clamp on mufflers for sale, they are the oddball 4.5 inch mufflers, will trade for JL stereo stuff or will sell for $1400 for all 4, all hardware is there, will also ship.

4.5 isnt odd ball Im sure there are plenty out there running them or bigger.......... glwts

my central engine is on 4.5
both outside on 4's...
go find out why i have no clue! but it is what it is!

Clean mufflers by the way !

what is the model of those custom marine silencers by the way?
any way to tell that? i know they have a model called ''sound elimination'' that is kinda approved in my area
so wondering if that is what they are...

The ones listed are the CMI Sound Elimination mufflers.

The back stays closed like that or does it swing open with exhaust pressure ?
Actually thats a dumb question there is only 3 little slits in the back that would be quite restrictive if it didn`t swing open

Dan if they’re like the ones I use to have - the rear plates go straight back under exh pressure. Spring actuating. If I recall anyway. Just another project that went by the wayside along with parts etc. lol

Kinda what I need but not but do ya know 😳

Now I’m questioning my thought. Also what about running them dry?

Damm SB. Some things never change!!! 😂👍
