Is this okay for stock UZ (autotrans)

[MonkeyGod]

Hi guys, for the header the diameter 1.7" and then 2.5" all the way
Is that will be ok for autotrans? Do I get enough torque for take off
and for the mid range? , thank you for your comment

Those sizes are WAY too big and will definitely hurt your low end and midrange and probably less top end also.

Go with 1.5" primaries and 2.25" duals or even 2.0" duals for best torque.
