Why hasn't anyone suggested $200 speed daddy's?
Ive installed more sets of these then probably any two people on this forum.

-Fitment is hit or miss. Some sets take 5+ hours to install while others take half the ammount of time.
-Leaking crossover is hit or miss also. Ive had sets with SUPER loose slip fits and sets with super tight ones.
-Downpipe sits LOOOW to the ground especially on lowered cars and the downpipe pieces need to be welded together.
-Flex isnt the greatest. Ive seen the flex fall apart on a good handful of cars in part because of the low quality flex but also because the downpipe sits so low that whenever it hits anything it puts a lot of stress on the flex and they can rip/tear/break.

Besides the issues I listed above... they are a good header lol. Regardless of the loose/tight crossover slip fits you can remedy that issue with two $10 "sheet metal" style band clamps. Flex can be replaced. Downpipe can be fixed to remedy ground clearance issues.

That all being said... I would buy Speed Daddys for my own car because I can fix them.
