Thanks for the information Bob. Iam getting a lot of good advice of which
direction to head into first. I really wanted to stay away from the computer route
because of the cost of premium gas. I like the cheap stuff just fine, heheh. As
for the HEADERS do you find that the ypipe going down is any lower than the
original OEM part on your dak? Reason being iam concerned about ground clearence
because i go offroad alot on little goat trails taking my boat to good fishing
holes. Need the good ground clearence my 2WD dak provides.
Thanks!
