see if you can get in touch with poor judgement on the os pipe... I still run the stock engine in the truck... no need to change... I don't see the need to run a special break in fuel especially lower nitro content... I run whatever I get which happens to be blue thunder.... I have seen the new era pipe and it looks nice... I have a friend with it on his truck... with the exception of it being louder, I don't think its any faster....
