2. Attach the Exhaust to the Downpipes

Using the bolts you saved from the stock exhaust, connect the Akrapovic system to the downpipes. Tighten the bolts securely, ensuring there are no leaks.

3. Secure the Exhaust Hangers

Slide the exhaust hangers onto the chassis mounts. Make sure the exhaust is properly aligned and adjust as necessary before securing the hangers completely.

Final Steps

Once the Akrapovic exhaust system is installed, it’s time to finalize the installation and check for any issues.

1. Inspect the Installation

Double-check all connections, bolts, and hangers to ensure everything is secure. Look for any signs of misalignment or potential leaks.
