When you add the total cost of the part and if you had to pay someone to install them you only end up with minimal gains your heart will sink. Intakes, test pipes, exhaust, and tune will extract about as much as it can. If you added headers you might gain 4 more hp. Is that worth it? Plus you might have to have another tune to find it.
Remember are engines are a vaccum that sucks and blows
. It can only suck in so much without being forced in. Then it pushes out what was taken in. So when you add so much NA mods on the exhaust side (exhaust, HFC's or TP) it can only ''free up" so much. So if your running let's say a 2.5'' exhaust and TP's you have increased a lot more flow already. The stock manifolds are a little restricted but also not so much in the end unless you were going for a NA build.
