I have OBX's and I wish I would have measured them before I put them on.

Ive heard that they have 1-3/4 primaries and like 2.5inch collectors.

I wish I would have done more reasearch on headers before I bought my OBXs. Becuase it looks like the OBXs are way to big for a relatively stock 5.3.

They are really well built headers, but I havent noticed any diffrence from them.

Ive heard that 2 into 1 headers are really good for low end and power thorught the rev range. Does anybody around here have any?
