i looked at the obx one, seems to have a bigger size to it than the other resonated test pipes, the info on it says that it works as a cat, with the chemical reactions and such, but whats inside, can you see through it, or is there actuall materials inside the pipe? And its late now, but i will look on my car tomorrow, but i thought that the o2 was on the cat near the flange closer to the header side...but you said both sound the same, thats good, i will save a lot of money not getting the prestigious random technology cat for over 200 dollars, thanks
