6.7L Stock Exhaust
 

Going to do the deletes on my truck as well as add a programmer, and I was wondering what the stock exhaust is made of? Just wondering if its worth the extra money to get a stainless steel or just go with an aluminized?

Stock exhaust is aluminized steel. Just my .02, I'd run aluminized, and put the difference towards other mods. It's also a lot cheaper to replace if it ever gets damaged.

Aluminized will be fine thats what I have and like EXTBlueRam it is cheaper to replace if something ever happends.

Aluminized, unless you just really want ss.

Depends where you live and what kind of salt they use on the road. Aluminized would last 2 years here but stainless will last 6+. Consider labour if you aren't doing it yourself and make your choice.
