Exhaust swap- new gasket(s) or not?

Swapping out my TRD exhaust for a stock one and wanted to know from folks who have done it, should I replace the gasket(s). I'm at appx 3500 miles and the "donor" vehicle is at appx 5000 miles.

TIA

 

I would just for the peace of mind of not having to go back under the truck to replace the used gasket that failed to properly seal. how much is a gasket ... 5 to 10 bucks?

 

I went from stock to the pro. The pro gasket was smaller than my stock one and wore out quickly. I reused my stock one and haven’t had a issue since.

 

I ordered the gasket.
