Jeep YJ Wrangler Replacement Exhausts

Your engine powers you over the roughest terrain and on to glory. A Jeep Wrangler engine must be a reliable runner to get you through those remote places you like to visit. Now, upgrading or restoring performance is easy. Just bolt on a steady air flow solution with a new Jeep Wrangler YJ Exhaust System.

The Importance of Exhaust Manifolds
The exhaust manifold draws excess heat away from your engine. If there is a crack in the old manifold or a leak in the gaskets, you may have noticed a ticking noise from the engine compartment. That's exhaust pressure escaping. When that happens, the fumes from your combustion chamber can't move away from the cylinder heads as quickly. Heat gets trapped, and you can end up burning your engine's valves.


The YJ Wranglers came with three different engines, and you need parts that fit for each component. Our Jeep YJ exhaust systems are designed to integrate with your existing engine profile. Installing one of these repairs leaks and restores the air flow characteristics of your exhaust. It is also a good idea to replace your Jeep YJ muffler at the same time.

Exhaust Accessories
Exhaust work is often a challenge. The water content in the fumes causes the metals in the headers and pipes to rust over time. It is common for bolts to seize up and for hangers and brackets to snap. Even if you win the struggle to remove these parts, they may be damaged and unusable.  


Be prepared with replacement hardware for your Jeep exhaust system project. These extra components are affordable and make the job of installing new pipes and mufflers easier. They also protect your new system when you drive. Properly secured exhaust systems do not break free and bounce on the ground.
