Mazda is a very popular and classic brand name of an automotive manufacturer which was founded in 1920 by Japanese. Nowadays it has up to millions of users all over the world with quite a wide range of segmentation for SUV, racing, sport cars or business style from luxury to low lines products. We definitely can buy a Mazda everywhere in the world and also with the spare parts. It is now easier for you to get an OEM replacement done with a reasonable price; these parts are good and can be chosen.
However, the OEM replacements don’t work for all users. Most of car performance enthusiasts will need something more than just an original car given such as headers or wheel spacers. But there are not really Mazda headers or Mazda wheel spacers because those parts of a car are mostly produced by an aftermarket companies. Some of new users may ask questions like do we really need Mazda headers or wheel spacers. It’s your choice.
Generally speaking, the headers are operated directly to the exhaust system and to help to optimize the flow of exhaust gas and indeed increase the performance of your car. Luckily, most of the time the exhaust system can be custom generated. The old restrictive manifold will be replaced and the new precision built of a header will bring you car a new breath. You sure will have Mazda headers with a custom design for your car by a custom shop according to the sizing and other stuff. Most of the manufacturer will allow you to build extra stuff inside as long as it’s not directly connect to the engine which is not recommended.
In this case, you will indeed need an OEM replacement. Wheel spacers are also made by the aftermarket manufacturer which will solve most of the fitment issues and give you extra stability. But they may have a not good affection on the link of the wheel and the hub.
Some of them will be quite expensive for its advanced function. You need to look carefully not only what you need but what your car really needs. You may ask some experts or professional engineers to see before you go for reinforcement. However, if you decide to make some extra installment, you may come to some trusted aftermarket companies which offer reasonable options for your Mazda like JAB headers or Eibach wheel spacers.
