thetz99, I've followed your thread(s) for some time. I'm having slight droning issues that I'd want to resolve. After reading I'm not sure which process netted the best results between quiet and rust prevention?
Just a few questions if you don't mind:

After ~2yrs, have you any issues? observations? approx miles?
You spoke of Boeshield, is that still being used?
My application is a custom 3" Stainless pipes w/ maganaflows (for FI)
If I don't plan to jet hot coat, what procedures you recommend?

Thanks again for the sharing your info and experience!!

Hey Sarek! How's that turbo spoolin

Most of the drone damp is from the Damplifier Pro (high temp dynomat). The Jet hot coat keeps the pipe cooler (~400F vs 550F @ vtec) so the dynomat doesn't crisp off. The heat wrap basically sops up and maintains the dynomat layer.

After 2 years, ~18k miles, the wrap has not aged too much, but I don't drive it in the wet anymore since I retired...you won't see too much water where you are anyways.

I use boeshield on my rotors and it really does wonders on keeping the air cooling vents. edges, and hat areas rust free. I did use it on the magnaflow setup I use to have and I believe it kept the tig joints relatively rust free as well.

In your situation with the spooler, the pipe temps will be 100F hotter even with the jethot. You might want to investigate getting a good sized resonator. Heat wrap does have a drone damp effect and I got good results when I had the magnaflows...Invidias are much deeper than magnaflows tho so I had to go all out.

Did you ever think about dynomating the passenger floorboard? That gives great drone control results for the effort as does the spare wheel area as described in another one of my drone suppression threads.

Every little bit results in a noticible reduction.

Burnt polymers on metal are never easy to get off btw.

i thought heat wrap creates bad rust problems...

i cant imagine taking the wrap off to find my exhaust all destroyed.
