Description
Superior Engine Boost. Replace the old, faulty cast-iron manifold of your TJ with this brand-new Exhaust Manifold Kit for a significant improvement in overall performance. The 6-to-1 collector effectively reduces turbulence and facilitates a more efficient exhaust flow. Furthermore, this assembly has greater exhaust scavenging ability, minimal turbulence, and enhanced exhaust flow over the restrictive factory manifold.
Aggressive Exhaust Sound. This Exhaust Manifold Kit is engineered to produce a bold exhaust tone that enhances your Wrangler’s outdoor confidence. Moreover, the manifold appropriately goes with your Jeep’s reinforced engine performance, as it gives off an aggressive roar while accelerating and cruising through the roads and trails.
Heavy-Duty Components. Built to withstand harsh impacts from the power-generating combustion process, this Exhaust Manifold is constructed using heavy-duty steel tubing. This mandrel-bent manifold is fully welded for high durability. In addition, this kit includes a CNC-machined gasket and front pipe seal to eliminate cracking and ensure a perfect fit. It also comes with welded ports for oxygen sensors that maintain your factory emissions controls.
Application. This Exhaust Manifold Kit is specifically designed to be used on all 1997 to 1999 4.0L Jeep Wrangler TJ models.
