C2damofoj 16 Report post Posted November 17, 2013 engine or burner exhaust? I am gathering parts to link 3 engines to 1 exhaust system, and run it thru the floor of my open trailer. Its too easy to get burned with mufflers everywhere. I will probably use a car muffler at the end of the line. Im using 1" gas pipe with weld fittings. They have 45 90 180, long sweeps-endless possibilities for fittings. Thinking about wrapping all the pipe with header wrap. Share this post Link to post Share on other sites

FullBlast 14 Report post Posted November 26, 2013 I have been thinking of doing the same thing to my box truck this winter. It will help put the noise down under the truck along with the fumes!! I am still in the thinking stage as well Guy!! Share this post Link to post Share on other sites
Greg R 82 Report post Posted November 26, 2013 I did on our Indiana Prowash build. I used 2" automotive exhaust pipe welded to a flange that 90'd and goes through the floor (a 4" hole with a metal flange bracket). This was off of a 16 HP Briggs vtwin with the low mount muffler so a 2" flange bolted right up to it though. On high mounts I would bet flex pipe would be a better option. It echos being under the truck but it keeps the box pretty clean and exhaust free. Share this post Link to post Share on other sites

Rapid HotClean 26 Report post Posted November 27, 2013 Maybe a it would be good to consider running it thru a car muffler once it is under the truck. Possible inordinante amount of power loss and/or engine heat buildup due to a larger auto-type muffler? Share this post Link to post Share on other sites
C2damofoj 16 Report post Posted November 27, 2013 Very possible, could make engine run rough from excess backpressure. I know Honda has many muffler configurations for their engines, most of which will bolt right up to any Honda twin. Briggs and Kohler probably make several styles of mufflers as well.

FullBlast 14 Report post Posted December 4, 2013 As long as it is big enough to not cause any back pressure I think it would be fine. A two inch muffler has quite a bit a flow and would be plenty big for a small two cylinder engine I would think. Share this post Link to post Share on other sites
