* Remove the muffler. This is the most obvious way to make your exhaust louder. However, it will also make your car more obnoxious and may not be legal in your area.
* Install a straight pipe. A straight pipe is a pipe that goes directly from the engine to the tailpipe. This will also make your exhaust louder, but it will also make your car less efficient and may cause it to run hotter.
* Drill holes in your muffler. This is a less permanent way to make your exhaust louder. Simply drill a few holes in the muffler and you will notice a difference in the sound.
* Use a resonator delete. A resonator delete is a section of pipe that replaces the resonator in your exhaust system. This will make your exhaust louder and give it a more aggressive sound.
* Install a header. Headers are a type of exhaust manifold that is designed to improve the flow of exhaust gases. This can also make your exhaust louder and give it a more performance-oriented sound.
Before you make any modifications to your exhaust system, it is important to do some research to make sure that they are legal in your area. You should also consider the impact that the modifications will have on the performance of your car.
