Here we will show you how to install a new one in your automobile. It is important to note that some of the steps may vary depending on the truck and engine you have installed. Step 1: The first step of the installation is to remove the exhaust system part connecting to your truck. To do this, you will need a tool called an angle grinder with cutoff disks. Once you have removed all the bolts and screws holding it in place, you can use towels or gloves to protect yourself from any sharp edges. After that, pull off the old pipe by moving it slightly up and down until it comes loose. When removing parts such as these, make sure no leftover pieces are hanging out. The reason is they will be challenging to remove later on when reinstalling everything together. So always double-check before putting anything back into place. Now cover your entire engine bay (both sides) with some tarp or plastic sheeting for protection against dirt, debris, etc. Step 2: The next step in the installation is to attach the new pipe to the engine head by screwing it on with a wrench. Do not use any lubrication or adhesive on the bolts, screws, etc. It can cause rust and other buildups in your system. In addition, it will eventually ruin all components over time. Also, it makes them very difficult to remove later once they begin corroding inside. So, keep everything dry for now until you have applied some sealant when ready. Always make sure both ends are lined up before moving on to attaching anything else such as hangers. Otherwise, you could install things at an angle. It will prevent proper drainage from occurring below where all pipes meet together, creating a bottleneck effect causing back pressure and thus reduces power and increases gas emissions even more. Step 3: The next step in the installation is attaching the hangers themselves. It is generally either welded or bolted on to prevent them from coming loose under severe vibration over time. Make sure everything is lined up correctly. After that, start tightening down all bolts in a criss-cross pattern. Also, make sure nothing twists out of place by placing your feet against it for leverage before getting too carried away. Finally, apply some sealant around both ends where they meet together. It will help prevent water buildup and corrosion once you begin driving down the road at high speeds constantly. Moreover, keep an eye out for any leaks. If you notice blue smoke coming from exhaust after installation, it denotes engine oil leakage from engine. It is not the problem of your catalytic system. Thus communicate with your trusted mechanic to resolve the issue sooner. On the other hand, white smoke from exhaust denotes coolant leakage. Buyer guide (Exhaust System for GMC Sierra) Choosing the right catalytic can be tricky, especially if you are not sure what to look for. The first step is to know your vehicle and its needs. Are you looking for a performance exhaust system or just something that will get rid of the factory sound? Do you need a wide-body kit? There are many things to consider, but we have put together a buyer's guide to make it easier! Type of exhaust system: Before purchase, the first factor to consider is the type of exhaust you are looking to buy. There are two main types: performance and replacement systems. Performance system: A performance system is made with the specific goal of improving power, torque, or gas mileage. It does this by reducing back pressure to remove restrictions caused by your factory exhaust system. In terms of sound, these will make your car more aggressive while driving at low speeds. However, it's not too much when cruising on a highway. It should be noted that if you want something quieter than stock. Usually, no additional accessories need to be added to lower noise levels since most models come from the manufacturer. Replacement systems: Replacement systems provide similar benefits as their performance counterparts without the added noise and expense. As a result, these are a good choice for drivers who want to improve their car's sound. It does this without making it too loud or noticeable by others on the road. Material: The second factor you need to consider before purchase is the material. Most replacement systems are made of stainless steel or aluminized alloy. So that they can be pretty expensive compared to the standard models. The material needs heat with stand capability as the exhaust becomes hot while driving. Car system compatibility: The next factor you need to consider before your purchase is the car's system compatibility. There are many types of systems that you can use on your truck, depending on the manufacturer. So it is important to double-check if you want your product installed properly. Moreover, it fits in with all other parts, such as manifolds or catalytic converters. Price: Once these factors have been considered, they should make their purchase based on the price-performance ratio alone. There are some brands out there that will offer good quality within a reasonable price range. However, do not expect every model to provide excellent performance at an affordable price. Installation process: You may also consider adding points about the installation process. Make sure to pick the product that is easy to install.
