I'm going to swap out my OEM's for Rinehart 4 inch slip ons, will I need some type of sealant at the joint site?

If you use new clamps, probably not necessary. But I use copper hi-temp silicone at the joints, just to be on the safe side.

 

Ditto

 

Me too...and contrary to popular belief, I find them easier to remove with a thin layer of the copper goo

 

Thank You, I just ordered it from Amazon.com it will be here Tuesday.

I've removed and installed several pairs of mufflers and have never used any sealant. Never had a leak but if it does make removing the mufflers easier I would say its a good idea. They can be a little stubborn to remove!

 

If the stock clamps are good you shouldn't have any leaks. I don't use sealant but I smear some anti-seize in side the muffler. Sure makes them come off and on easier.

 

....yes, yes, yes, yes on the anti-seize, always.
