What's next? Headers or CF Driveshaft? You vote!
I'm on the fence... so I've put it to a poll. Headers or Carbon Fiber DS?
My current set-up is:
Coilovers
Figs 2 piece rotors all around
HPS Intake tube
I like doing road course events but I'm not sure which I'll benefit/enjoy more off. I'm also looking at buying a set of Forgeline wheels locally.

I'm not quite sure I follow your logic. It's been documented that going to a full exhaust only nets ~10 RWHP while headers on factory exhaust net ~30 RWHP and only gain the additional ~15 RWHP from finishing the exhaust.

My logic was only that you will not get the full benefit of the headers without the exhaust.
And when I saw thess vids below - I was surprised how much more HP is extracted when you add an exhaust to a existing headered F.
First race I had with him I was stock with 5,000km on the clock. He had his cat-back and below are the results:
M3 Vs ISF (P.1) - YouTube
Second race I had the PPE Headers installed and he had the same cat-back exhaust:
Lexus ISF Vs E92 M3 (P.2) - YouTube
Final video is with Joe-Z and PPE headers. I am also surprised at the difference, ESPECIALLY on low end torque and take off. Before installed the exhaust he would always get me from 1st to 3rd. But on my last race as you can see things have changed:
Lexus ISF Vs E92 M3 (P.3) - YouTube

I haven't done headers but I was the guy who got the initial driveshaft from DSS and tested it. I'm still using the 2nd produced and have done 3 drag race events with it, I can't verify the exact gains from it but one thing that is noticed is how you don't get a spongey launch from the guibos soaking up torque and the effect of steel shafts twisting and recoiling. I honestly feel this is a great buy for any one wanting to race their car alil bit or for those spirited streeters, the power is there and the DSS carbon will help decrease the already high power loss (for rwd) due to drivetrain design.
