07+ Cat C13 Delete

Looking for information from others who have deleted their 07+ C13's. How well did it work out? Was it worth it? Will this improve overall performance and life of the engine?

 

From what i understand, only discussing how to or where to, are not allowed as far as deletes go. I am simply asking because i am looking at adding a truck with an 08 C13, but these engines are not worth the trouble unless you delete them. With the standard emissions system on these engines for their respective year model youre looking at a rebuild every 500k to 650k. Id like user feedback from people who have gone ahead with the deletes to know if that will significantly extend the life of the engine. Other wise its not cost effective for me.
