If you need a new catalytic converter, it’s easy to get overwhelmed by the options available. There are all sorts of designs, coatings and materials to choose from, and there’s no one-size-fits-all solution for every vehicle. Still, you can follow some basic guidelines as you shop for a new high flow catalytic converter (HFC).
Check the design.
The first step in choosing a suitable catalytic converter is to look at its design. The most important thing you need to ensure is that the catalytic converter fits your car and will fit under it. If you’re replacing your old catalytic converter, this will take time and effort. You’ll have to get underneath the car and ensure enough space for a new catalytic converter to securely attach to any other parts, like exhaust pipes or manifolds.
Consider the coating.
The coating is a misnomer, as most catalytic converters do not have layers. Instead, they are made from different materials that are designed to be resistant to heat. There are three main types: ceramic, palladium and platinum. Ceramics offer the best durability but can crack when exposed to too much heat; palladium has better performance than ceramic but will rust over time; platinum is the most expensive, most durable, and most efficient.
The coating you choose will depend on how often you drive your vehicle. If you’re planning on buying an aftermarket part for your catalytic converter (which we don’t recommend), then make sure it comes with a warranty so that if anything happens down the road, they’ll cover it under their lifetime guarantee program so long as there’s no visible damage caused by poor installation practices or improper cleaning methods used during their lifetimes.”
Make sure it’s made of a suitable material.
You should also ensure the catalytic converter you purchase is made of a suitable material. Some states have stricter emissions laws than others, and a converter installed in one form may not be able to pass inspection in another. You’ll need to check with your local motor vehicle department (MVD) to find out if they require your car to meet specific standards before you can register it in their jurisdiction. It’s also important to know where you plan on driving your car and what terrain it will be driving through, as this can affect how efficient the catalytic converter will be at removing toxic gases from exhaust fumes. To ensure that your new high flow catalytic converter is compatible with your vehicle’s make and model, check its specifications and where it was manufactured.
Order a custom catalytic converter if necessary.
If you have a custom-built car or want to replace your catalytic converter with one of a different size, then you will need a custom converter. If you’ve ordered a custom-built vehicle, then the manufacturer should ensure that the correct size of the catalytic converter is included in your vehicle’s specifications. If not, it’s up to you to determine what type of cat is recommended for your car before making any changes.
Choose the right size.
You’ll be wasting money and air if it’s different from the correct size. Make sure that the converter fits in your vehicle’s engine compartment and that there are no other issues before buying one.
Each car requires a specific converter to work correctly with its engine. To find out what size will work best, consult your owner’s manual or call your local auto parts store and ask them if they can help you choose an appropriate catalytic converter for your car’s make and model.
After you’ve researched all of these factors, you should be able to pick a catalytic converter that will work best for your car and needs. You may find that it’s worth investing in a custom-built or upgraded model if your vehicle requires it or if you plan to drive in areas with more stringent emissions laws than where you live.
