speed daddy headers

there may B an answ above by clicking on "Tech Archive" (if U haven't looked its a great place to spend some time). Matt uses the same pipes Mike W. did - ie CI (some say identical to the SD).
My recolection is 5-10% HP boost but yer well beyond that all now w/the nice alu head...

I don’t know about just the header, but I will be running mine on a dyno and doing some tuning in April.
Will post the info on here once I get to it.

might there B a ticket from B4 (weren't U in LA, CA @ that time?) to see as a comparison?

I was yes, but currently in africa for my wife’s job. I haven’t gotten to do a dyno run yet, but when I am home in Louisiana this April I will be taking the car for a few runs and do a little tunning on the FItech and seeing how them 3.80 gears workout lol
