Yes-sir you nailed it with the new "Mac's Double Quiet Pipe". Pretty amazing how quick that thing jumps into go mode. Anyone looking for a pipe to go with their 58 take a good hard look at this pipe. It is whisper quiet without hardly any power loss.</p>

Mine was ripping very good too. My last flight, hottest part of the day had cylinder temps after landing of 229 and 188.... Super!!</p>
