Performance Exhaust Header

Your factory exhaust manifold is restricting both your 2001 GMC Jimmy sound and power. By upgrading to Performance Exhaust Headers, your making it easier for your engine to push exhaust gasses out of the manifold. With your performance exhaust manifold, each cylinder will get its own exhaust pipe, rather than sharing a common manifold. This will help you gain more horsepower and torque. Another added benefit to headers is you will increase the sound you crave.

Depending on your vehicle, and your intended use there are different headers you can go with. We carry a large inventory from leading manufacturers, which will include both short tube headers and long tube headers. Long tube headers like the name states, are much longer than short tube headers. They merge further out which results in even less backpressure. Long tube headers are ideal for high-rev vehicles, and racing. They build most power in the mid to high RPM range. These headers can also be difficult to install, or require some more work due to needing more space for the long tubes. Alternatively short tube headers merge in a shorter distance and are ideal for low-RPM power. For daily drivers and towing, these will build power the most power from idle to mid range. If you have any questions about what headers are best for you reach out to one of our experienced representatives and we will help you make a more informative decision.
