How to Measure Your Vehicle for the Perfect Fit of a Header-back Exhaust System

by

Installing a header-back exhaust system can significantly improve your vehicle’s performance and sound. To ensure a perfect fit, accurate measurements of your vehicle are essential. This guide will walk you through the steps to measure your car properly before purchasing or installing a new exhaust system.

Tools You’ll Need

  • Measuring tape
  • Marker or chalk
  • Notebook and pen
  • Helper (optional but recommended)

Step-by-Step Measurement Process

1. Measure the Overall Length

Start by measuring from the front of the vehicle (at the engine or the existing exhaust manifold) to the rear bumper. This will give you an idea of the total length needed for the exhaust system. Park your vehicle on a level surface and ensure it is turned off and cooled down.

2. Measure the Width and Height

Measure the width of the vehicle at the rear axle to ensure the exhaust pipes will fit comfortably without hitting the body or suspension components. Additionally, note the height clearance from the ground to the underside of the vehicle to confirm the exhaust’s height will not cause issues.

3. Measure the Exhaust Pipe Diameter

Determine the diameter of your current exhaust pipe at the connection points. Use the measuring tape to measure across the pipe’s opening, or refer to the existing specifications if available. This ensures the new exhaust system will connect properly.

Additional Tips for Accurate Measurements

For best results, have a helper assist you in holding the tape measure steady and marking measurements. Take multiple measurements at different points to account for any irregularities in the vehicle’s shape. Double-check your measurements before ordering or installing your exhaust system.

Conclusion

Accurate measurements are crucial for a perfect fit of your header-back exhaust system. By following these steps and tips, you can ensure your new exhaust will fit properly, enhancing your vehicle’s performance and sound. Always consult with a professional if you are unsure about your measurements or installation process.
