Best Exhaust System for Jeep WranglerJK

For bringing out the best in every ride

Off-road never runs off the track and JK Wrangler is one of the successful Jeep models used for the same. For the kind of terrain and the nature of the rides, enhanced performance is necessary for a satisfying journey.

The Best Exhaust System for Jeep WranglerJK, which is the critical part of the jeep, lets out filtered toxic fumes through a tailpipe. This assures its power and performance. While the factory exhaust lets your engine breathe, an alternate aftermarket upgrade will let it breathe effortlessly during the numerous off-road trips a JK Wrangler is destined to travel.

The exhaust that filters out the toxic gases offers displacement, which is directly proportional to power. So higher the displacement, higher is the power of the jeep.

These, with larger pipes and mufflers will allow smooth flow of gases hence better displacement thereby improving the overall efficiency and higher power for the vehicle.

The three major kinds of Exhausts systems that can be used in a Jeep Wrangler JK are:

  • Axle-Back Exhausts
  • Cat-Back Exhausts
  • Exhaust Headers

Axle-Back Exhausts are installed from the rear axle to the exhaust tip. These are affordable, improve the sound quality and the look of your Wrangler JK. But it doesn’t ensure performance gains, hence doesn’t improve efficiency. Therefore if you are aiming for increased power and performance, axle back may not be the option.

Cat-Back exhausts are installed from the catalytic convertor to the exhaust tip. These ensure better performance and sound. An aggressive or toned down sound becomes your choice. But these are expensive compared to the axle-back counterpart. 

Exhaust Headers are paired with the cat-back exhaust system. Headers separate exhaust into individual pipes. This increases exhaust flow hence more displacement, thereby ensuring more power. The two types of exhaust headers are shorty headers and long tube headers. Shorty headers require lesser components as it works with the factory catalytic converter. On the other hand the long tube headers replace the stock catalytic converter.

It shows an improved power and performance. But these are expensive, difficult to install and must be mandatorily paired with a cat-back exhaust system.
