Maintenance & Care for Your Z06 Exhaust System

Our resilient exhaust systems require minimal maintenance to maintain top-tier performance. To keep your Corvette exhaust system in great shape, we recommend: 

• Routine visual and auditory inspections to check for structural damage, loose connections, exhaust leaks, and other apparent issues

• Regular undercarriage cleaning to remove salt, debris, and other accumulations. Keeping the exhaust surfaces clean will help prevent premature material wear while making it easier to see any potential surface problems. 

• Professional maintenance: Every 6-12 months, invest in a mechanic inspection and/or thoroughly evaluate your system by lifting the vehicle. Tighten bolts, check the hangers, and ensure all components are aligned and functioning correctly.

• Drive with care. Avoiding rough terrain, salted roads, and other hazardous road conditions can help preserve your valuable systems.

Alongside proactive maintenance, we strongly recommend that you seek a professional installation when upgrading your exhaust system. Our specialists at Fabspeed Motorsport have over 29 years of car improvement expertise for a precision fit that will look, sound, and perform better than expected. 

SOUND:

This all out race exhaust turns the Z06’s 5.5l V8 exhaust note into a thoroughbred race sound. With a much more authoritative rumble at idle, and our signature X-pipe bringing out the a high pitched wail that, dare we say, exceeds that of the Ferrari 458. This system is LOUD, so don’t be surprised when you wake your neighbers every Sunday morning. All this sound and performance comes at the cost of some interior drone. For a drone free solution, we are developing a valvetronic exhaust that will have the best of both worlds.
