Nismo exhaust vs Stillen | FI | and everything else...

[BossJ]

I'm sure this question has been beat to death - I've looked on google and tried searching the forums. I couldn't find anything...

Does anyone know what the HP / torque gain is - when it comes down to putting a stillen CBE on a NISMO... I'm guessing what they say on their website is for the stock exhaust?


I don't want loud and drony. I know... any aftermarket CBE will give you more noise - it's the animal - BUT i hear stillen is a pretty good sound + not loud...

I'm just curious if it's even worth my money or if I should just go HFC + Muffler delete - (I know loud - but I want the performance)

...

Thank you! (I asked something similar to this in another thread) but I am really curious about the difference in performance gained. (I've been seeing like a 10hp gain over nismo - is that about right?)

-
also - if it is only a 10hp gain from Nismo exhaust and i'm not too concerned about sound - what if I just went this route (minus straight pipes I would go HFC) - https://www.z1motorsports.com/z1-pro...ge-p-7223.html
