lol ok ok... It's not that big of a deal. He asked about exhausts so the F.I. exhausts have baselines and then after install... they are all over 20 whp gain... there you have it I suppose.

I just have hard time believe that you can gain 20whp just by exhaust. Again not calling their are a lair but from what I understand, Nissan engineers did really good job on 370z, I can understand Stillen Gen3 intake add HP, but exhaust? Any FI owner had their car dyno?

The stock exhaust is actually very restrictive compared to aftermarket ones. Whichever breather mod you do first (intake, exhaust, test pipe/hfc) will give you the most gains. I think the exhaust and test pipes/HFC help more than intakes though.

Baseline dyno was 296 whp. After I installed the F.I. LTHs and F.I. CBE I redynoed a month later and got 326 whp. +30 whp with only those two mods and no tune.
