I would recommend a tweak mate will get the most out of the changes you have made but most of all with give you piece of mind knowing that all is well and safe. I have ported headers and Harvey uppipe the difference is very noticeable.

Second what harri said, you'll defo notice the difference after fitting those parts... And to get the most out of the mods and safety Id recommend a tweak
