Buying a Mustang EXM3 exhaust manifold for models with engines sized 260, 289, and 302 (produced between 1965 and 1970) comes with both benefits and drawbacks. Below, we'll outline these points to help you make an informed decision.

1. Performance Enhancement: A high-performance exhaust manifold can significantly improve engine performance by reducing back pressure and increasing exhaust gases' exit velocity. This results in more power and better acceleration.

2. Improved Engine Sound: The EXM3 exhaust manifold is known for its unique exhaust note. Installing this manifold can provide your Mustang with a more aggressive and desirable sound.

3. Durability: The EXM3 exhaust manifold is made of high-quality materials, ensuring its longevity and resistance to corrosion. This can save you from the cost and hassle of frequent repairs or replacements.

1. Installation Complexity: Installing a high-performance exhaust manifold like the EXM3 can be a challenging task, especially for those without automotive experience. It requires precise measurements, welding skills, and the proper tools.

2. Cost: The EXM3 exhaust manifold is a premium aftermarket part. Its price point is higher than that of the stock manifold, which may be a deterrent for some buyers.

3. Compatibility: While the EXM3 exhaust manifold is designed to fit Mustangs with 260, 289, and 302 engines, there may still be some degree of variation in engine bay configurations between different models. Ensure that the manifold will fit your specific car before making a purchase.

The decision to buy a Mustang EXM3 exhaust manifold for your 1965-1970 Mustang with a 260, 289, or 302 engine depends on your priorities. If you're looking for improved performance, a unique exhaust note, and durability, this part is worth considering. However, if you're not comfortable with the installation process or the higher cost, you may want to stick with the stock manifold. Ultimately, weigh the benefits against the drawbacks and make a decision that best suits your needs and budget.

If you decide to pursue the EXM3 exhaust manifold, we recommend seeking professional installation services to ensure a proper fit and optimal performance. Alternatively, if you're confident in your automotive abilities, carefully follow installation instructions and use high-quality welding equipment to minimize the risk of errors. Remember, the investment in a high-performance exhaust manifold can result in a more enjoyable driving experience.
