The guy I bought my bronco from ran the exhaust over the rear axle to the rear end, so anytime I drive with the top off or the rear window down I get the sweet smell of exhaust. I want to install new pipes that exit in front of the rear tires to avoid the extra bends to get over the axle and the risk of carbon monoxide poisoning. It looks like the easiest way is to have both pipes exit on the passenger side. Will the heat from the pipes cause uneven wear on the rear tires? Im also looking to install a set of headers. Any inputs on brand, type and whether or not they are really worth the money? 1990 302
