Your vehicle's exhaust manifold is responsible for keeping harmful gasses away from your engine to allow it to breathe freely and function more efficiently. With all the abuse this part takes, it is best to get one that is durable enough to handle the heat under your car's hood. To find out which brand can cope with exhaust gases more competently, we've installed a Replacement exhaust manifold on our 98 Wrangler and observed its performance weeks after installation.
- Made of high-quality stainless steel and other heat-controlling materials
- Tubular design for 6-cylinder engine
- OE-replacement fit and style
- Sold individually
- Comes with a 1-year, unlimited-mileage warranty
- The Replacement exhaust manifold looked beefier and sturdier than the original part it replaced. It even appeared twice as thick as the Wrangler's stock. This stronger frame shows better handling when it comes to thermal expansion, which causes cracking in an exhaust's housing.
- The part's tubing was also more solidly-built and featured a strong stainless steel construction. Its welds were identical to that of the original equipment.
- During installation of the new exhaust manifold, we were impressed with how the part fit flawlessly in our Wrangler. Its drop-in OEM fit and quality allowed our team to slap in the new part with no modifications. It fitted right and lined up perfectly with the rest of the parts under the hood.
- Before replacing the part, our Wrangler was experiencing loss of power. We found out that this was caused by a crack in its old manifold. Installing the Replacement exhaust manifold solved this problem soon after installation.
- We also observed that the replacement part keeps the noise under the compartment at bay. While test-driving the Wrangler, we were at ease with how at peace the engine was.
- Gas mileage slightly improved a few weeks after installation.
- Installation can be a bit difficult and is best left to a certified technician or mechanic. The design of the system is more complicated than the usual manifold and might require some degree of experience in order to get it into the vehicle. However, as our mechanic pointed out, this part had a good match and fit.
- The part did not come with new studs and bolts. We had to salvage the existing hardware from the old manifold to avoid incurring extra costs.
- It also required a new heat shield and exhaust manifold gasket, which was not included with the part.
- Although the replacement manifold came with plugs, they didn't have fittings for 3/4 tube options.
The Replacement exhaust manifold combines both the quality of an OEM part and the low price of an aftermarket replacement. It heavy-duty stainless steel construction and durable tubing and seals provides this drop-in replacement part with reliability and steady performance often associated with originally manufactured parts. Price is also one of this part's main selling points. However, this part is not recommended for novices who wish to save more by installing the parts themselves. The lack of necessary hardware such as bolts and heat shields can be quite an inconvenience. So be sure to invest on a good mechanic's work if you're planning to use this as a replacement for your car's original equipment.
