If your engine is in good tune with propper AFRs you should not see crazy heat like some of my mufflers have been exposed to. I would LOVE to use aluminum but it just isn't practical for all the various applications and range (or lack of) of tune.
Please do report back as I have never personally seen aluminum used in a turbo application. N/A typically produces a lot less localized heat.
