Tecumseh exhaust

[Stilly 0]

Just bought lawn ranger no exhaust.   6 hp Tecumseh motor.   Is exhaust thread 3/4 black pipe?    Would like to run two elbows from block and have muffler face up.   Will I need to brace??

the Lawn Ranger had a brace on the exhaust , and  i'd certainly recommend  using one

I dont remember the size of the threads in the block and dont have one handy to look at.

Yes run a brace, I have seen 2 Tecumseh blocks that have cracked into the exhaust port because of not running one.

I've got a stack o my tractor, definitely brace it, I've got mine braced at two points you can almost lift the tractors front end off the ground with it! all it would take is a branch  or someone bashing into it to crack the block.
stacks are nice though, makes the tractor sound much nicer i think

What type of muffler are you using?  I don't want a stack but would like something quieter.

Back in high school a buddy did his RJ58 with a nice set up - I just can't remember what he used...

don't be fooled! my stack is pretty quite, so much so you can hear the slight tap of the valves (in person), or are you just not into the whole stack look?  the muffler I've got is a stainless steel 1.5", the type with the perforated tube inside. i think what also helps with mine is that it from the outlet the is a 180 degree twist followed by a 90 degree bends before it goes into the stack you can also get baffles that slip inside the exhaust.  you can also see it is quite tall which also helps somewhat.
heres a pic:





here is a video from my youtube channel. it is as loud as it appears in the video really:
 

hope this helps, don't rule out stacks, they are very simple to build and sound loads better than a pepper pot type exhaust (in my opinion that is  )

This is what I did

This is my setup.  Harley muffler cut down both ends using muffler like slammer screwed down holding in place.  Wish I would have left more pipe on top.  Sounds great.  Fumes are bit of a problem when starting.  How do I post picture trying copy paste does work.

to post a pic i used photo bucket, you upload the picture to there then they give you a URL to copy and paste. when you post you message the picture will be there. there is also the add media button just above the submit reply button, never used this feature for pics though, only youtube videos. 

fumes aren't a problem for me, my stack is tall enough and i think the rain cap helps to deflect it all.
