Okay, I ordered my Blue Spring Kit and was also wondering if anyone had any thoughts on Sinister's EGR Delete and Coolant Filtration Kits:

6.0 Powerstroke 03-07 EGR Delete & Coolant Filter Kit | eBay

I also am wanting to do a 4" or 5" Turbo back straight exhaust but needed to know if it would throw any codes or the CEL? Has anyone done this and are there any issues I need to be aware of for the exhaust, EGR delete or coolant filtration system?

Thanks in advanced for your imput,

Yeah, its an 04. Thanks. I appreciate the feed back. I had heard that going to straight pipes would throw codes but I wanted to check before I did it.
