Safety Precautions for Exhaust System Users
We have repeatedly talked about the risky nature of exhaust systems while discussing the right buying decisions. But you also need to be cautious during the time of your installation and use of the product in your truck.
You may consider following these pre-purchase and after-purchase precautionary steps to avoid any accident:
- If you are living in a dry area of the USA, go for aluminized steel muffler. If the air of the area you are residing is highly humid then stainless steel muffler should be your right choice.
- The more powerful your exhaust system is, the more noise will be created by it. So before purchasing a system with race-ready muffler and increased flow, make sure that the sound won’t cross the local decibel limit. Usually, in most of US states 95db is the limit for street applications. Performance mufflers are better in bringing out natural tone than OEM mufflers
- The exhaust system of your vehicle is that one part which goes through the harshest roads and faces all the roughness of snowy, muddy and sandy routes. It cools, cleans and removes the toxic gases out of the system. Thus this system needs regular maintenance, inspection and repairing.
- When you find your fuel getting finished in an unusual speed and, peculiar sounds and burning smell coming from the engine, you should immediately inspect your vehicle as these signs indicate a leak in the system.
