Wouldn't it have just been easier to get rid of your egt problems?If it's on a daily driver that rarely if ever see's 1200* then yes, the Hypermax kit works great. It has on several trucks I've installed them on.
However, I've bought 3 hypermax uppipes, as well as their upgraded one. 150 for each pipe and 300 for the one upgraded pipe. 750 bucks for just pipes in the past year.
Yeah... I'm glad I took that dumbass donut style setup off my truck. Hell I could almost buy Carsons whole kit with what I've paid for in just pipes from Hypermax.
Carsons kit albeit modified is going back on the truck once it's completed.
