Frank, the only thing that's available currently is the GGB Extreme. The rest [to my knowledge] will have a melt down.Originally Posted by 10x
CMI has a new muffler for dry pipes that's in testing. It should be released in the spring.
The GGB's appear to be holding up well and those who've bought them give me good reports. I don't have any real decibel readings on them with dry pipes though.
