Exhaust Adapters & Connectors

FAQs Concerning Exhaust Adapters

What does the exhaust system do?
Exhaust systems play an important role in carrying noxious gases away from the internal combustion engine and out through the tailpipe where those gases are dispersed in the atmosphere. The exhaust is also a popular modification to performance cars, or just getting that perfect exhaust note. Over time, exhaust pipes can break, though. When this occurs, a connection must be made. This is where an exhaust adapter or connector comes in.
Where do you make the connection?
Wherever the break occurs. The best case scenario is a break in the middle of the pipe, where you can easily connect piping of the same circumference. But should the break occur at a flange, you can still make a connection that will last.

How to Choose a New Exhaust Adapter or Connector

There is no 'one size fits all' measurement when it comes to exhaust pipes. Indeed, you'll find piping, muffler and collector reducers of various sizes. Unless you have a shop manual specific to your vehicle, you'll need to measure the outer dimension of the pipe to obtain the right sizes.
First, only make your measurements once the exhaust pipe has cooled. You're at risk of acquiring third-degree burns if you come in contact with a hot pipe. In some cases, you may need to place the front of your vehicle on lifts to access space underneath. Use a creeper to move under and out from under your vehicle.
Second, with a tape measure in hand, measure one section of the pipe's outer diameter. Measure it again to ensure the two numbers are exact. Then, do likewise with the other side of the pipe.
Third, stop by our page to search for the correct part. With your measurements in hand, you'll make the right purchase. You can also input your vehicle information to narrow the parts list accordingly.

Types of Exhaust Adapters and Connectors

• Standard fitment - The easiest exhaust connector is the one where both sides have the same diameter. Sometimes referenced as a butt joint, this low-cost connector is typically constructed from aluminized steel for maximum durability.
• Flex connector - If you're concerned your connection may break, a flex connector is an ideal option. Flex pipes are routinely used on front-wheel drive and some all-wheel drive models with that extra flexibility offsetting the rocking motion that can crack a pipe.
• Exhaust elbow - Not all breaks connect straight parts. This is where an exhaust elbow brings two very different sections together. So there is no need for you to head to the muffler shop to have a pipe bent.
• Reducer fitment - Sometimes, the break is so small that a standard fitment won't do. This is where a reducer comes in, offering a stub version of the full fitment. Reducers are sometimes known as exhaust adapters.

How to Install Exhaust Connectors & Adapters

Installing an exhaust connector means having the correct part for your vehicle as well as one or two clamps. The clamp will fit over the connector, holding it in place. If using a standard fitment, flex connector or an exhaust elbow, you'll need two clamps. For a reducer fitment, one clamp may do.

How to Install a Connector

1. With the car cooled down and jacked, slide underneath the vehicle to locate the break. Bring with you the exhaust connector and clamps.
2. Fit the correct size section of the exhaust connector with the pipe. Then connect the other section. The connector should successfully reconnect the broken pipe.
3. Secure everything in place by clamping each end of the connector. Don't neglect this step as the clamps will ensure the pipe stays together.
4. Take the vehicle for a test drive and confirm any abnormal sounds are gone.

What if my catalytic converter is also presenting a problem? Most frequently, your check engine light will come on. You might also notice a smell of rotten eggs or a rattling noise. A code reader tool will help you make this diagnosis. What can I do if I want improved performance? Once your exhaust connector is repaired, consider what you'll do when it comes time to replace the exhaust system. You might opt for performance exhaust headers, which provide a power boost you'll notice immediately. Can I modify my car for enhanced performance? Your stock exhaust system is what the manufacturer determined is best for your car. In most cases, the OE's system dampens noise and restricts airflow. A performance exhaust system will boost power and provide the sweeter exhaust note you crave.
