HEY GUYS I HAVE AN 02 3800 MC SS. I GOT THESE SPEED DADDY HEADERS A WHILE AGO AND IM LOOKING TO PUT EM IN NOW. I BOUGHT SOME ARP STUDS FROM ZZP AND THE SHOP TOLD ME IT WAS THE WRONG SIZE. DOES ANYONE NO WAT SIZE I NEED?
i tried getting in touch with speed daddy and they never answer any emails or calls unless your trying to buy something..nasty people
ALSO IF THERE IS A DOWN PIPE ANYONE NO'S OF THAT WOULD BE GREAT OTHERWISE ill probably buy a 3" pipe and have em bend it in.

thanks
