I've read a few things on here and did my best trying to research the answer to my question but can't seem to find a definite answer, so I'm hoping one of you experts can help me out!

I have a 2016 Nismo and want to get a new exhaust for it. I was eyeing the HKS Hi-Power exhaust as it seems well respected and reviewed here. It sounds great (definitely louder and better sounding than stock!) and price is right around where I am looking to spend. However, all threads I am seeing of people buying that exhaust aren't Nismo models, so I'm not sure how the HP gains compare by putting it on a Nismo model.

So my question to all of you guys is this: If I were to get an exhaust for my 2016 Nismo, would the HSK Hi-Power increase or decrease my HP? And if it decreases, which exhaust would you recommend that sounds similar (or louder works too!) and is around the same price?

Thank you all!
