ebinmaine 68,861 #1 Posted June 10, 2017 I have a '74 B80 I picked up last fall . The exhaust I have is a "stack" made of the muffler from a late 70's 10-12 HP cub and a short piece of pipe to get it away from the hood. I like the tone and low noise level a lot and I need to make it taller to get the fumes out of my face when driving. Mine needs to be as light weight as possible and maybe another 2 feet long (tall). The only thing I can think of is maybe thin chrome sink drain pipe? How did you make the exhaust on yours? Thanks! 1 Share this post Link to post Share on other sites

Chris G 3,296 #5 Posted June 10, 2017 (edited) I used the chrome plated drain pipe. Just cut it off at the elbow. I haven't had no issues and it was on one tractor for a year and got transfered to another for about 6 months now. But the stainless bath rails work even better I was told and also theres a guy in the classifieds who sells chrome tipped muffler stacks. Also depending on how big you make your stack and especially be aware of the weight. Cause a stack has been known to Crack a block if it's not braced up. So my advice definitely brace your stack with a good support. Edited June 10, 2017 by Chris G 4 Share this post Link to post Share on other sites

cafoose 3,355 #7 Posted June 10, 2017 I just got one from @jimkemp and I'm very pleased with it. Check out my post to see some You need to scroll down near the end of the post to see the pictures. The inlet is threaded and you can use any length of pipe you want. 1 Share this post Link to post Share on other sites

The weight and vibration need to be compensated for by bracing the stack to the top of the engine or the tractor itself. 1 Share this post Link to post Share on other sites

ebinmaine 68,861 #11 Posted June 13, 2017 I ended up buying the longer portion of this: http://www.homedepot.com/p/Everbilt-1-1-2-in-Brass-S-Trap-C720-1/205153843?MERCH=REC-_-rv_nav_plp_rr-_-NA-_-205153843-_-N I'll cut the elbow 1/2 way or so and get the exhaust pointed away from myself just above eye level instead of sternum level. And its CHROME. Shiny is good. 2 Share this post Link to post Share on other sites
Chris G 3,296 #12 Posted June 13, 2017 (edited) Same thing I used. Light weight and has held up over all pretty well. Edited June 13, 2017 by Chris G 1 Share this post Link to post Share on other sites
