I plan on buying a set of Pypes LT with a catted H, a set of Detroit Rockers and a set of ford racing 3.73 gears. I plan on buying from Brenspeed and having then install. Will i need anything else other than a tune? Has anyone had this same set up done from Breenspeed? If so what was the total cost? ( I know i could just call or email Breenspeed but I have to wait till Monday for that )
