TJ5208 1,841 #1 Posted October 19, 2021 (edited) would a stack limit power because I have a Ih1 stack I want to put on rebel but I didn't know if it would lower power how big is the exhaust port Edited October 19, 2021 by TJ salyers Share this post Link to post Share on other sites
Maxwell-8 4,367 #2 Posted October 19, 2021 (edited) Don't think you are going to notice a power increase/decrease. these small engines don't rev high enhough for it to have influence. Is that the fuel hose going trough the engine cover? Edited October 19, 2021 by Maxwell-8 1 Share this post Link to post Share on other sites

If your using an IH muffler, I believe that it is designed to be a slip fit over 1" water pipe. 1 Share this post Link to post Share on other sites

True... but also depends on the size of the pipe and length of the stack. Longer length you run, bigger pipe might be helpful... Don 1 Share this post Link to post Share on other sites
