It's cheap to mod a car that way. The exhaust mods are expensive. A set of good headers alone cost as much as all those mods put together. Maybe they just want to sell parts? I don't know. But from what I've learned, you need headers and dp on top of those mods to run a 3.4. That's why my 3.4 is still in the box! waiting on exhaust mods! LOL
