Product Overview


Year  Model  Generation  Engine  Quantity Per vehicle 
2003-2006 Montero Gen3 3.8L V6 1


These are the only aftermarket Exhaust Manifolds for the 3.8L available in the USA so if your Montero has a cracked manifold (as is very common on the original OEM ones), your options currently are: 
1. New OEM manifold for around $350 from Mitsubishi
2. Aftermarket Headers shipped from Australia for around $800-$1,000 (added welding, drilling, spacers may be required)
3. Used Junkyard unit - but high probability it has cracks in it as well 
4. This new aftermarket manifold for less than 1/2 the price of the OEM unit.
As you can see, these are not Swiss quality made parts. The castings will have imperfections and pits, the heat shield threads are often not perfectly centered, and there are visible hand grinding/finishing marks. But this unit will bolt up correctly and will get you back on the road for less than 1/2 the price of OEM. We've used these manifolds on our own Monteros, have sold many over the last 2 years, and have yet to see or hear of a single failure.
2 Exhaust Manifold Flange studs are included: interchange Mitsubishi Part Number MR497545
Don't forget the gaskets! For best results, using new gaskets (not included) ensures a proper seal:
ACCESSORIES: Includes 2 Exhaust Manifold Flange Studs 
*This part is for the Full Size Montero, NOT the Montero Sport. 3.8L Engine only.

    Both exhaust manifolds fit perfectly and feel heavy duty.
