do the 3 pipe mod aswell if your still using the airbox as it just restricts air getting into the box...
the vec c pipe has a larger diameter so more air is able to get in quicker, but depending on the price it may be an idea to get the custom inlet pipe made by 'EarlofBarnet' like I have, nice bit of engine bay bling and i should imagine a much better flow 🙂
