Actually, I asked a similar question in the exhaust/intake forum and didn't get an answer. Specifically, "is there a direct comparison in hp gains between the factory nismo exhaust and various aftermarket equivalents (FI, Greddy, Stillen, Berk).
Still haven't found anything concrete. Although I did find a guy who had a FI exhast that switched back to the nismo because the hp gains were "negligable" o_O
At any rate, I've put the exhaust at the end of my bolt-on upgrade list behind my already installed intake, HFCs and headers. Not crazy about the exhaust note on the nismo but that's cosmetic.
Stillen G3 intake already installed, berk HFCs and Stillen ceramic headers up next + uprev tune. Question though, if I decide to go with something other than the nismo exhaust after that, will I need yet another tune?
