Love your dark blue GT3. The system went to Canada. Wish I could have used it here in Cali. Got a GMG center by-pass for the time being. It's been great to do a few track days to keep me sharp when not racing the other car.
Take Care,

Got some headers.
I went with a used set of GMG's w/ no cats from a rennlist member.
Primary reason was to avoid OEM cat's failing.
Weight oem headers. vs. gmg catless headers.
OEM= 5084 grams
GMG= 4082 grams
net difference 1002 grams x 2 = 2004 grams reduced.
OEM headers have very nice welds, that porting would be no help, from the factory for those of you wondering.
Will update later this week w/ logs of oem vs. gmg.

Outside Temperature 55 when I did oem setup
Outside Temperature 62 when i did with gmg headers
I did port the GMG headers as over-lapping material internally.
Same location.
enjoy the data.
3rd gear runs therefore no "driver error".

Yep. Uncorking the cats alone gives a few ponies :-)

Understatement according to the data. 10 runs before 10 runs after, all runs show improvement. Pretty conclusive. Both on Aim Solo & Harry' Dyno app show improvement.
Now i have enough power to accelerate as quickly as GT4's

Nice. I was eyeing these headers as well, but you got to them before I did. If you ever want to sell let me know.

I saw the thread pm Roger for payment email and where to send shipping label too.
We should meet up sometime and you can hear the headers in person - not to rub it in of course.
