zanepetty 117 #1 Posted January 30, 2014 I bought a stack for my 753 but I'm worried about it breaking my engine cast. Is there an alternative muffler I could use as a stack that wouldn't require a brace? If not, and I have to use a brace for any stack, how could I make a brace for this muffler? Thanks in advance. 1 Share this post Link to post Share on other sites
bmsgaffer 2,043 #2 Posted January 30, 2014 Im no expert on stacks, but It looks like you could welt a mounting tab on the muffler and add a strap to one the the head bolts. (I'm not sure if this is frowned upon, but all three of my kohlers came with some sort of right angle bracket from the factory under a head bolt) That may interfere with your hood, but you would have to check. Basically gravity is just adding a pretty large force right at the connection to the engine so you need to help "un-twist" that force. You cen either lift from below or pull back towards the engine from above. I hope that made sense. Share this post Link to post Share on other sites
