ATP Parts 101212 Exhaust Manifold

Stainless Exhaust Manifold for Jeep Applications

ATP Parts 101212 is a replacement exhaust manifold for select Jeep models from 1991-1999. It uses stainless steel construction to resist rust and replace a damaged original header that can leak exhaust gases into the engine bay.

This ATP 101212 exhaust manifold is built for Jeep Cherokee, Wrangler, TJ, and Comanche applications where the original manifold has cracked, corroded, or begun leaking at the flange or gasket surface.

Key Features

• Stainless steel exhaust manifold construction for improved corrosion resistance
• Direct replacement for select Jeep Cherokee, Wrangler, TJ, and Comanche models
• Addresses exhaust leaks caused by rusted or damaged original headers
• Includes manifold gasket, dump gasket, hex bolts, and lock nuts
• Part number 101212 for fitment verification and ordering

Detailed Description

The ATP Parts 101212 exhaust manifold is a replacement header designed to route exhaust gases from the engine into the exhaust system on supported Jeep vehicles. Compared with the original steel manifold, this stainless steel version offers better resistance to rust, which is important on older vehicles where heat cycling and corrosion often lead to cracks, leaks, and noise. For buyers searching for a Jeep Cherokee exhaust manifold, Jeep Wrangler header replacement, or Jeep Comanche exhaust manifold, this part provides a direct-fit repair option.

This part cross-references Monroe Shocks & Struts (e.g., 3271533, 4883385) for the same application.

What It Helps Fix

• Exhaust leaks at the manifold or flange
• Rust damage on the original header
• Ticking or hissing noises from a cracked manifold
• Hot exhaust gases entering the engine compartment
• Reduced sealing at the exhaust connection points

Installation Notes and Tips

Verify engine and chassis fitment before installation, since this manifold is listed for specific Jeep Cherokee, Wrangler, TJ, and Comanche model years. Inspect the cylinder head flange, dump connection, and surrounding exhaust components for damage before bolting the new manifold in place. Use the included gasket and fasteners during installation, and confirm all mating surfaces are clean and flat for proper sealing.

Quality Assurance

ATP Parts supplies this manifold as an improved aftermarket stainless steel replacement for the original header. Limited lifetime warranty coverage is listed for select applications, and California sales restrictions apply where noted in the fitment data.
