Invidia N1 question

[ErlDzn_FB6]

I'm thinking of getting the N1 for my 2014 si sedan. Which would be better the 70mm piping or the 76mm? There is about $100 difference, is it worth it? Would there be any difference in gains or sound? All I have is the HPS silicone intake tube and a k&n drop in filter. As of now I don't have any plans of doing anything else performance wise. If I ever change my mind the most I would do is intake/downpipe/flashpro. I will only stay NA and not go boost. I tried using search but couldn't find any answers.

For NA 70mm isnt going to be a restriction. That said the stock exhaust isnt a restriction until you upgrade the downpipe.

Buy a DP and install it together to make better gains.

I think you should be fine with the 70mm and spend the 100 somewhere else, that's what I have lol
