How to Choose a Muffler for that Perfect Growl
Upgrading to an aftermarket muffler is one of the greatest joys of guys who want to add presence to their vehicles. But choosing a new muffler is more than just making your vehicle sound louder. If you just slap on some muffler, you can end up with just crackling noise instead of that deep tone you are looking for. More than that, it can affect the response of your vehicle. To avoid these things from happening, we want to help you out with your quest to get that perfect engine growl by pointing you to the right direction.
Mufflers do not follow the principle of working well with all the engine types. There are certain mufflers that can be complementary to your engine's performance while there are others will just make you cry over spilled milk. When you set out to look for a muffler, make sure you take note if it made for a petrol or diesel engine. Also find out if it is compatible for a four banger, six banger, V6, or a V8 block.
Inlet and outlet specifications
You would want to make sure if the inlet and outlet provisions will match the pipes you have in your vehicle. The factors that you have to consider for the specifications are the pipe diameter and position. You can check this by putting your ride on a lift and examining the undercarriage. Take good measurements so that you can have a smooth installation without the need of extensive modification.
Now we go to the exhaust notes. Finding the right sound that suits your preference can sometimes be tricky. For muscle car enthusiasts, they would want that deep throaty rumble that announces their presence blocks away. The aggressive sound that it produces outside can be perfect. But if you continue to hear that loud tone inside, it can also be tiring. You will have to find the perfect balance between exterior and interior resonance without forgetting if it can bring out the best tone coming from the headers.
A Quick Guide to DIY Muffler Installation
Replacing a muffler is one of the easiest things to do in terms of restoring your vehicle's proper functions. It is something that can be accomplished without a lot of complexities. All you need are basic tools and you are ready to do the job.
(Note: These are general instructions for all types of vehicles.)
Difficulty Level: Moderate
- Floor jack
- Ramps or jack stands
- A variety of wrenches and ratchets
- Propane torch
- Exhaust hangers
- Rag and cleaner
- Protective glasses
- Replacement nuts and bolts
- Replacement gaskets
- New muffler
- Go near your muffler, which is located under the rear section of your vehicle.
- Elevate your automobile using a jack and have it supported by ramps or jack stands. You should not get under your car with only a jack supporting it.
- Closely inspect the setup of your muffler. There should be three or four bolts in every pipe to keep it in place. The muffler should be connected to your vehicle's body with rubber muffler hangers.
- Spray the bolts thoroughly with a penetrating lubricant to take the rust out. After a while, see if you can remove them. If the bolts are extremely rusted, you may have to spray it liberally again and let it sit for a day before you can take them out.
- Use the floor jack to get the muffler sufficiently elevated, so there will be less tension on the muffler hangers. After that, you can pull the hangers off with your hands.
- Remove the bolts on the mufflers using wrenches or ratchets. If the lubricant wasn't able to loosen the bolts, you may have to use a propane torch to get them out. Be careful in applying heat to the bolts.
- Take out your old muffler.
- Put in your new muffler by using new bolts nuts. Be sure to put replacement gaskets in between the two sections of exhaust.
- Use new exhaust hangers to hang your new muffler from the body of your vehicle.
- Get the muffler at the right height by lowering the floor jack. Tighten the bolts of the muffler hanger brackets for it to be firmly attached.
- Take away the floor jack. Start your automobile to see if the attachment points have leaks. If you notice a leak, you may have to reinstall the gaskets.
- If there are no leaks, then you can turn your engine off. After that, lower your vehicle to the ground. It's finally finished!
