We do make a wraparound style Pitts for the MVVS/EVOLUTION 45. Its not listed on the website yet because we are totally redoing the site. We did all the prototype work for Horizon on the Evolution gas engines. (same as MVVS)

The power is very good on them and they work well on noise. I suspect the gentleman that bought a muffler for his G62 in a warbird probably has one of the upright-inverted box type in cowl mufflers. Lets put it this way, in cowl box type mufflers will not be the quietest muffler due to there volume no matter who manufactures it.

The wraparound pitts style that we make for both the MVVS /EVOLUTION 45 and 58 weigh 8.4 oz and are all tig welded for durability..

Here are a couple of pictures of the wraparound style mufflers that we make. We can customize them to fit you plane also as we build them when ordered.

In one of the photos you will notice a larger pitts style wraparound, this is our large style pitts .I t has much larger volume can. This style muffler has been tested on a DA 50 with noise results at 95db at 9 feet and 94 db at 9.8 feet. It will fit most planes in the 50 to 80 cc class.
