Slightly step on the gas pedal and observe the behavior of the entire exhaust system. Listen out for abnormal sounds, leaks, and vibrations. Should you detect any leakage in the exhaust line, you must identify and fix it appropriately. If the leak is coming from the muffler outlet, you should disengage the attachment and check the seals.
Otherwise, the car muffler should operate smoothly. It depends on the laws of your country. It is illegal in most countries due to pollution. Your engine is not affected. However, for the sake of your comfort and wellbeing, we suggest keeping your muffler intact.
The quickest sign is abnormal noise. If your engine starts producing a squeaking sound, that is your signal to have the muffler checked. Also, if you feel an unusual vibration or notice a decrease in fuel efficiency, it could be time to replace that muffler. You most definitely will part with a few dollars but not necessarily cause a dent in your finances. The life cycle of a muffler depends on routine maintenance.
To prolong its life, proper installation and continuous readjustments and part replacements are necessary. The car muffler remains an integral part of the vehicle and can endure all road conditions if well maintained. Bear in mind that if you want your car to take care of you on the road, take care of it in the garage.

Most exhaust piping comes in two or two-and-a-half-inch diameters. You will not be able to seal the wrong size pipe onto another pipe, even if you overtighten the muffler clamps. With the piping seated properly, slide a muffler clamp over the area where one pipe overlaps the other. Use a hand or socket wrench to tighten the clamp until it is not possible to move the pipes back and forth at all.
You may want to use a half inch drive wrench to tighten the clamps to ensure you have enough leverage to tighten it sufficiently. Be sure you tighten the clamp over where the piping overlaps, otherwise you could crush the exhaust piping. Reconnect the battery. Start the engine to check for leaks. Ensure vehicles equipped with automatic transmissions are in park and those with standard transmissions are in neutral with the front wheels securely chocked.
Start the car and look beneath it at where the muffler and exhaust piping meet. An exhaust leak would likely be visible if there is one. If you are unsure about whether there may be a leak, ask a friend to press down on the gas pedal slightly to increase the RPMs of the engine. This will make leaks more apparent.
If you identify a leak, allow the piping to cool off and try to assess its cause. You may need to remove the muffler clamp and seat the two pipes together properly before re-tightening the clamp. Most modern mufflers use one of two types of fittings. The most common for OEM is clamped, as shown in the article.
Aftermarket mufflers universal ones may need a flange welded on if it is a catback system, as an exhaust shop will generally break the long pipe down into smaller parts.
Aftermarket exhausts made for your vehicle, however, should either bolt straight on or slide on. Not Helpful 0 Helpful 4. The inlet always faces the engine; that's the side the gases are coming into.

Connect sections of your system with exhaust clamps, if needed. Get exhaust clamps, which are metal loops that you can tighten around pipes to hold them together, from your local hardware or automotive store.
Tighten the clamp with a ratchet so it holds the pieces tightly. You may also have extension pipes that connect between some of the pieces.
In some cases, you may need to weld the pieces together rather than use clamps, so see what the manufacturer recommends. Plug the oxygen sensors back into the ports on your vehicle. Locate the small holes in the sides of the exhaust pipe near the front axle of your vehicle. Slide the old oxygen sensors back into the holes and tighten them by hand by turning the bolts clockwise.
Slide the metal pins on the system into the rubber exhaust hangers. The metal pins will line up with the rubber hangers you already have under your vehicle. Apply firm pressure until you see the end of the pin poke through the other side of the hanger.
Continue putting the pins through the other hangers to secure the pipe against your vehicle. Tighten the bolts at the front of the exhaust until they form a tight seal. Go back to the front of your exhaust system and use your ratchet to rotate the nuts clockwise. Be careful not to overtighten them since you could damage the exhaust system or cause leaks.
Spray the connections with soapy water to see if there are any leaks. Fill a bottle with soapy water and spray any areas where you had to connect pipes to one another. If you notice bubbles forming around the connection, tighten the bolts more to see if it fixes your problem.
The only fluid that you might encounter is water. This might occur if the outside temperatures are pretty low or humidity is very high. The water might actually be brownish due to the dirt inside the exhaust system. Not Helpful 1 Helpful 4. Not Helpful 0 Helpful 3. Position each ramp right in front of a tire, get in the car, and gradually but steadily apply the gas. Have a friend watch and guide you to make sure the tires are positioned perfectly on each ramp. That lowers the risk of scraping your bumper, or worse, driving off the ramp.
Put the parking brake on, put a block behind the other tires, and you're good to go. Helpful 1 Not Helpful 0. Helpful 0 Not Helpful 0. Avoid driving once you remove the old exhaust system since it may be illegal in your area and you will emit a lot of harmful fumes.
