I have reused the nuts on three Slings. My current one has about 7000 miles since the supercharger. Never been a problem.
I reused the nuts when I installed my 1320 header. That was 18 months and 22,000 miles ago. Not one issue.
Installing a 1320 V2 header, and muffler this weekend, and from what I’ve read it is not recommended to reuse the nuts from exhaust manifold studs? I looked at OEM nuts, but at $4.20 each there has to be a better way? I’ve read that it’s best to go back with copper coated, but not sure if I can source local, or even proper size?
Thanks.
Where did you get this BS from? Reuse the nuts. There is nothing wrong with them.
Some Hi-temp anti-seize wouldn't hurt

I have used anti seize for 50 or so years but I do not think that is a place I would be using it. "IMHO"

From the Factory Polaris service manual. “Remove exhaust stud nuts, and discard” I assume due to being repeatedly heated, and cooled it causes distortion resulting in exhaust leak? Or it makes them $48.00! Take your pick

They are in the business to sell replacement parts, just do not try to build an SS from the parts you probably could not afford it.

It is a spec for the type of locking nut that is used ... they have "interference threads" in that the thread pattern in the nut is tighter than the stud so it locks on to the stud and won't loosen due to heat cycling ... technically they are single use only ....
You can get 25 copper replacements for $17 delivered ..... https://www.ebay.com/itm/40093…geName=STRK%3AMEBIDX%3AIT

Thanks guys. I will do the same.
Whatever you decide to do. Retorque the nuts after a heat cycle. Personally I do this twice, even when using a good torque wrench. There is one nut that you will not get a socket on. So find a wrench that will work and check the torque with the wrench on one that you could use the torque wrench, so that you can get the feel for how tight to go with just the wrench. I hope that you understand that.
Thanks ORANGEMAN,I needed a set of those.
Some nuts are slightly egg shaped too...for that locking reason...they would round out upon installation....so removing them you lose the locking action by reuse.
Agree with the masses. Reuse them and don't worry about it.
