Not to long ago my brother hit a tree not to hard, but there is a kink in the exhaust.(no holes). So we refiber glassesed and everything, We put the muffler on with the kink because my dad's friend at work said it would be fine, but i didnt think so. And now were one day from leaving from going up north and with teh muffler on and the kink where the bend is, it is really loud. It has a super low idle like around 500rpm and after a little bit it dies down. Do you think there is to much bach pressure which is making this?

What happens when you ride it, like full rpms? Can you notice a difference there?

I didnt ride it but i lifted it up and the top end isnt to high there is no rpm gauge i estimated around 500 but i'm thinkin even lower for the idle. Once u get it past that low idle point to where the idle point should be its kinda ok but still really loud to.

Check for exhaust leak. It's possible that there's a crack somewhere that you may not have seen when inspecting it, or perhaps it developed a crack shortly after. Dad's 600 sled came with a similar kink in the exhaust, but it continues to run fine. If there's enough exhaust leaking, you will lose back pressure and it won't want to run at all and will be very loud. But you should be able to see the exhaust if it's too bad. Could also be valves, did you check those?
