The muffler that came with the S29 is literally the same size muffler that came with the X11. It is about 1/3 the volume of a typical .25 sized muffler. I have not used it yet. If anything, it probably ran the same that the muffler would allow - about 3,000rpm short of the open exhaust reading. I normally use a full tuned pipe on my S29 that gives about 16,400 on a 9x5 APC and 5% nitro.
