esky 73

yeh coby headers not to flash, we tried lots of different styles on our formular ford, we were getting 120hp out of a kent with the best set, however they were fuckin expensive. 1 7/8 primarys with 1 3/8 anti reversions cant remember the exact length of the anti reversion but we tried a variety of lengths also the order the primarys go into the collector makes a difference to, dont know if this is any help or not
