Types of Exhaust Pipes
There are many types of exhaust pipes one can put on their car or truck. Some are built as standard replacements for stock exhaust pipes whereas others are made for performance applications.
- Header-Back Exhaust Pipes replace all parts from the header to the tail pipe and can be very expensive.
- Cat-Back Exhaust Pipes replace all parts from the catalytic converter to the tail pipe and are less expansive.
- Axle-Back Exhaust Pipes also provide horsepower improvements and a different sound, but are much less expensive and easier to install yourself.
- Dual Exhaust vs. Dual-Tip Exhaust: Dual exhaust has two distinct exhaust pipes from the header or catalytic converter to the exhaust pipe tips, whereas the dual-tip exhausts have two tips at the end of one exhaust pipe extending back from the header.
How to Install an Exhaust Pipe
How far back in the exhaust system you decide to replace will determine how intricate or simple it will be to install an exhaust pipe. If the only part of the system you’re touching is the muffler and exhaust pipe tips, then it’s a simple job requiring only a few hours of time. Header-back systems may take a few days for first-time DIYers.
- Jack up your vehicle, ensure stability
- Determine which parts are being replaced
- Test fit your parts to ensure they’ll work
- Unbolt previous exhaust system from car
- Starting from the front of the car and working back, install new components
