A body magnum exhaust solution

I'm with Kraby on this one. I haven't had any luck with it either on exhaust. I have read every tube I can find and the highest temp rated stuff I've seen was around 850-900 degrees. Exhaust temp gets alot hotter than that.

Other than that Braveseal things look real good. Apparently I missed some earlier post that others read. Was the problem with the mating up of TTI headers to magnum heads?
