Does anyone have any 4" slip in used mufflers for sale? Thanks, Chris

I have a pair of 4" GGB inserts, which are for 4" I.D. tubes. They were in my Stellngs for 10 hrs.
Great mufflers, they dropped the decibels by 10+, but I needed more to be legal. Cost was $600+, I'll give you a good deal, PM me if you’re interested.

Thoose are nice but I was trying to find somthing that was less expensive it is for a stock motor. Like the CP Thanks

Fred, are you talking $149 each or $149 for a set of two? When GGB quotes these things they say per pair, but in their world that means each or $298 total per engine.

What is the length of the ones you have? Mine are about 10".

You can buy these on Ebay for $59.95 a pair.

I bought the slip in silencers offered by Eddie Marine through Fred at Trick Marine. I am happy with them on a twin 496HO application. I don't know the decible drop, but it is definately significant. No real peformance loss; maybe 1 mph. I bought them with the intent to only install when running on Smith Mountain Lake where noise is becoming an issue. I kinda like them now and never took them out.

I've got a pair that look like the picture posted by CPPerformance. I bought them from Rex Marine for $99 and used them one season on my stock 454. I'll sell them for $25 plus whatever it costs to ship to you. PM me if you'd like them. They knock the sound down but weren't quiet enough for my upgraded motor.

go to jegs and get the vortech cones

I think there's 2 sets in my buddy's garage. Let me know if you need them , they look like the $59.00 ones on ebay. BBB
