When it comes to engine performance, what comes out is just as important as what goes in. The purpose of an exhaust system is to efficiently remove as much used gas and heat from the engine as possible. Exchanging clean air for dirty air helps the engine run more efficiently and improves gas mileage, power, and lowers emissions. Catalytic converters, mufflers, headers, cat-back systems, exhaust gaskets, pipes, and manifolds are all common components of most exhaust systems that a Jeep Wrangler enthusiast will replace with upgraded aftermarket parts. Upgrading a single part may not be enough to improve the engine's overall efficiency, which is why many JK owners replace their entire exhaust systems before they take their vehicles off road. Two complementary Wrangler mods that help you get everything out of your new exhaust are aftermarket intake kits and a Jeep Wrangler performance chip. These mods combine with a better flowing exhaust to allow your JK to more efficiently process air through the engine, netting you serious power gains.
