Looking for the approximate exhaust manifold and muffler temperatures for a 16 hp B&S horizontal Vanguard engine.

 

I installed a $125 B&S muffler on the used engine I put in my JD 140H3.  The muffler was only about 1/2" away from the electric clutch driven pulley and the belt melted and stretched after about 15 minutes of mowing last fall.  The manifold and muffler temps were in the 380* to 450* range.

 

Today I replaced the exhaust manifold with 3/4" black pipe, one elbow, one tee, a couple of pieces of black pipe and the original kohler muffler.  The original exhaust manifold tubes were less than 3/4" ID.  The temps are down to the 310 to 350* range.

 

The pipes are now about 3" from the pulley and there is enough room to put in a hear shield.  The muffler is on the right side and outside the engine compartment so the heat should be much cooler.  I do need to put a guard around around the muffler to keep the grandkids safer.

Thanks for the link.  I looked at a similar product yesterday at the local NAPA store.  It was 15' for about $20 so this would be a better deal.  I wonder how it would hold up to the weather if I used it to wrap the muffler and if 340* would be enough heat to "cure" it?
