So I took a chance... I already had the vararam cold air intake. I decided to get the obx long tube headers with catless mid pipes in order to save some money for a cam swap. The install was painless. I had no problems whatsoever with the fit of these headers. It took me about 4 hours with the help of 2 of my cousins taking pizza and beer beaks. We reused the stock bolts and gaskets.
I still need to get a tune but I want to get the tune the same time I do my cam swap.
I built some rear o2 sensor extensions using spark plug non fouler and a fuel filters for a 70 model blazer. So far I've put 1500+ miles on the car with no check engine light! So far I'm happy very these headers
