Today, on our shelves, you will have a chance to find our great variety of the Infiniti QX4 Exhaust Parts. These parts are created to help the exhaust system of your lovely vehicle function much better. Besides, all of them need to work in harmony, because if one of them is broken, the system will not be able to work. Do you know what components we are talking about? They are the exhaust catalyst, the exhaust pipes, the exhaust manifold, the muffler, and the tail pipe. Moreover, they are used to perform specific functions for the entire mechanism to operate.
The exhaust manifold is the first element that the exhaust gases pass through. Its function is to burn any leftover fuel, which was not burned, and funnel it down through the exhaust pipes to the exhaust catalyst. The latter, in its turn, converts harmful pollutants into less toxic substances before they leave the vehicle. Then, the exhaust gases go through the muffler that is used to reduce the growling sounds that can be caused by the traveling exhaust flow. And finally, the exhaust gases pass through the tail pipe.

- Replacement Exhaust PartsExhaust Clamps, Gaskets & Hangers | Don’t Skimp on the Small Stuff!Exhaust system gaskets, clamps, and hanger pieces are probably some of the most overlooked parts on your entire vehicle. Since you don't see them, clean them, or maintain them, they're usually out of mind until they become degraded and fail. And degraded they are, because whenever exhaust pipes and mufflers are replaced, these old support pieces are usually always corroded beyond the point of re-using.
- Performance Exhaust SystemsWhy Do Some Replacement Exhaust Manifolds Come With Catalytic Converters?If you're looking for a replacement exhaust manifold, you may notice that the choices available for your specific vehicle are only available with an "integrated" catalytic converter. In the same way, a search for a replacement catalytic converter may only turn up "combination" converter/manifold products.
- Replacement Exhaust PartsDirect Fit vs. Universal MufflersRegardless of whether you're shopping for a simple replacement muffler that delivers original equipment (OE) sound and performance or an upgraded muffler which provides a deeper growl with increased power through freer exhaust flow, you'll see choices between "direct fit" mufflers and "universal" mufflers. In this article, we'll help you understand the differences between these two styles so you can make a more informed purchase.
