those exhausts really make that much whp gain?

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.

OP-you don't mention brand. What brand exhaust was it?

I like the tone of the Invidia with the ART TP's, but i'm not that impressed with Invidia's numbers to be honest.

True, but a bunch of other people felt the difference as well, but that could have been the sound too. I swear I saw the speedo go up quicker than before when I got into the triple digit range

I'm trying but you're all the way in Bama. According to the butt dyno, I should be able to get there quicker now

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.

I don't have a dyno but I have a decent feel for my car. I put 5K on it before I modded it. I installed a Topspeed CBE and it it felt a little better. Still rather quiet but a nice deep tone. A couple weeks later (Sunday night) I installed a T/S y pipe and Surewin (cheap ebay) test pipes. It is much louder and kinda of fart can sounding over 3K rpm. I haven't really ripped on to see how much it changed, but I lights up the VDC light on gear changes like it did stock in the winter. I have sport tires and it was 107 F today. The sport tires are not very tacky in single digits.

I also went from averaging 20-21 mpg/tank stock
23ish just T/S CBE
now with 1/4 tank burned I am hovering around 24.
