Hey guys, I'm looking for ways to increase air flow, lower the exhaust temps, and hopefully help with mpg on the truck. Is this a worthwhile upgrade to invest in, or would my money be better spent elsewhere?

Save your money, put it towards a turbo. Then maybe a set of stixs.

If you tow heavy, you are gonna need one. But I'd opt for a turbo and injectors first. With
my setup I have to push it REALLY hard to get it over 1100 degrees. .02.
