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 ?

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.

Due to the configuration of my exhaust set up and water exit, I definitely need to use clamp-ons. This is what seems to be limiting my options. thanks anyway though.

Nobody running or have any experience with Shotgun type set ups?

I have the Livorsi E-Series on my 525's. Like them alot. Quiet at idle and then growl while running! Good luck.

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

Livorsi no longer sells the E-Series. They now sell the CMI Sound Elimination Mufflers.

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.

Lofty,

Can you provide more info on these upcoming units? Pricing? Available in clamp-on? Will they work for my described set-up? thanks in advance.

Regards, Mark
