Seeking Exhaust Advice

If you can possibly afford it, a coating (like jet hot) is a great idea, not even so much for looks as to keep engine compartment Temps down, and ad to the life of the headers.
My fenderwell custom headers, my custom under chassis headers (both V8s swapped into tiny foreign cars, so custom) and my old hooker adjustable have all been coated. The only way to go in my opinion.
I'd probably install em, make sure any dents, dings or holes in the car needed are done, the exhaust is plumbed, and then pull the headers out and send em out for coating.
