I don't even feel heat from the muffler on the step above the exhaust.
The strap around the muffler is 1/4" or better and is bolted to the bottom of the case so the exhaust is pretty rigid. It is also high enough up that driving over high things is not really a problem.
This tip I made on the end of the muffler fans out the exhaust so very well that there is no dirt, dust, grass clippings or loose debris displaced or blown up from the flow. Even placing ones hand in close proximity around this tip there is no hard pulse from the exhaust to feel.
I got this idea from late model diesel products that use thermal reduction tips on the exhaust for the current diesel exhaust emissions. Not only does it reduce the exit temps of the exhaust but I noticed how it fanned out the flow so that there was no direct stream to blow on surrounding areas.
This is quiet exhaust but the straight up pipe and muffler is more quiet than this garden style.
