Re: what mufflers?
I havn't heard of any of the mufflers holding up with big motors and no water. If anyone has any info to the contrary please post it. I have 6" totaly dry cmi and over 1100 hp to quiet down.
Hey Ratickle did you get my reply on the Flame Arrestors ?

Re: what mufflers?
I used Corsa mufflers on two boats successfully, and never lost top speed. I replaced the Corsa's on my current boat because I wanted to try and get even quieter, and switched to Gibson bullets. The Gibson's may be very slightly less loud, but because I also upgraded the engine, I don't have a perfect before and after comparison for noise or top speed. This may not be the correct place to mention this, but I have the Corsa's for sale. They are thru-transom mounted for a 4" exhaust hose. They have 6 1/2" diameter bowls that Corsa says are good to 600 HP with no performance loss, and also have external salisbury flappers. I used them only one summer and they look like new. I'd be happy to get $300 for them.

The Livorsi's are a good unit however they are not recommended for my set-up due to where the water mixes in.
The Gibson downturns would definitely work however I think they will be too quiet for my taste. Still want to hear a little growl at idle

I think Lofty on here has access to GGB. I run them on 600 CU IN 750 HP NA and they work great. could not tell any difference from before and after except a little rich in the mid range.

GGB is no longer producing marine products. A very similar product will be on the market early in 07'. It's a exploits the same technology as the GGB's with some real improvements to construction. We are promised the first production run in January.
