RTV on Exhaust Pipes?

I'm installing my Stainless Works retro-chambered catback exhaust this weekend and saw in the instructions to use high-temp RTV sealant between the pipe joints.

I've read online that it's not really necessary and may make it more difficult to ensure proper fit around the underbody during assembly (i.e., more difficult to adjust pipes when sealed with RTV).

Perhaps overtime with the thermal cycles and carbon in the exhaust the joints may seal themselves? Otherwise, what's the big deal, I doubt I would hear a difference?

What have others done??

I've done exhausts both ways. It actually makes it easier to move the pipes around before it sets up. I like good tight sealing joints.

Never used it. The quality wide-band clamps do a great job of sealing on their own.

Unnecessary. The clamps and piping themselves are such higher quality/grade now, that they wont leak.

They are designed as well that the natural flow of the pipe/overlap isnt condusive to leaking. i.e., the exhaust would have to travel up-stream to leak.

Dont need the sealant. Its eaither a weld, or no weld system.

Snug them up tight. NEVER use Loctite on anything you might want to remove at a later date.
