What size headers are these

[1qk50]

They are MAC LT's for a T-5. I am thinking 1 3/4, what do you guys think?

Looks like 1 3/4" but could be 1 7/8"....

 

[82hatch]

My guess is 1 3/4"

 

[frddriver]

I'd say 1 3/4"

 

[1qk50]

Well the guy that is selling them says they are 1 5/8's!
Could he be wrong?

Why do you hate them?

 

[MentalMisfit]

prolly cause they are mac's and mac's usually have fitment issues. Or at least thats what I've heard I know I try not to buy macs.

But don't mac's flow the best out of the "Off the shelf" headers?
