there are certain things that statement holds true but it seems like some things, doesn't seem to matter.
For instance, an obx intake is no differnt from an injen intake except for the filter. Obx shifter shifter, a knock off of C's, seems to have little complaint. An ebay down pipe, test pipe, is no different from an hks/greddy/invidia one. Exhausts however, due to the material used for sound resonation and flow, matters.
An exhaust manifold, from my understanding, is no different from an intake arm or a down pipe. There are no tricks to it, at least is per my understanding. Which is why I come to you guys asking for opinions.
Of course I know you get what you paid for. Don't get me wrong, I wouldn't mind spending on a hks manifold but I would like to know HOW and WHY it would matter between 2 similar products.
