exess4 Posted September 1, 2010 Share Posted September 1, 2010 found a good deal on 77 XS360 mufflers, I know, i know, different displacement - even different part # ! , but what would the result be exactly. Too much back pressure? Carb tuning? Runs bad? Shortens life of motor? Link to comment Share on other sites More sharing options...

exess4 Posted September 2, 2010 Author Share Posted September 2, 2010 just buy them, maybe slightly different cone shape at the end, but that's about it. I knew I was asking the right person and guru; makes perfect sense - different shape (however slight), different part number. However i did make a partially thorough effort to search the YOC and found nothing. From what I can tell from 'stock' photos that I've found I cannot tell the difference. Microfiche are identical drawings (i think). So was hoping this could be expanded on; different cone shape, would that not mean slightly more restricted airflow. Hope this isn't all so adamantine of me, soooo, I'll probably just buy them Link to comment Share on other sites More sharing options...
