#629 - 06/10/02 10:27 PM 89 K Jimmy header upgrade
Anonymous Unregistered	I have an 89 full size Jimmy. I want to put Headers on the stock engine, i've heard that it is not a great idea. Apparently it reduces back pressure in the exhaust, thus, reducing power. I've always believed that headers are beneficial. Can someone please tell me yes or no for headers?
