Frequently Asked Questions
Everything you need to know about GGB Exhaust performance products.
Will installing a GGB exhaust void my vehicle warranty?
In most jurisdictions, the Magnuson-Moss Warranty Act protects consumers, meaning a manufacturer cannot void your warranty simply for installing an aftermarket part unless they can prove that part caused a specific failure.
Do I need to recalibrate my engine or 're-jet' after installation?
Most GGB exhaust systems are designed to work with stock fuel mapping; however, for optimum performance on certain high-altitude or modified machines, a fuel controller may be recommended.
How long does shipping take for domestic orders?
Orders are typically processed within 1-2 business days. Standard shipping within North America generally takes 3-7 business days depending on your location.
What is your return policy for exhaust systems?
We offer a 30-day return policy on unused and uninstalled products in their original packaging. Please note that once an exhaust has been installed and run, it is no longer eligible for return.
How do GGB exhaust systems compare to stock mufflers in terms of weight?
Our performance mufflers are significantly lighter than OEM units, often providing a weight savings of 5 to 10 pounds depending on the specific model and application.
Are GGB exhausts trail-legal in all areas?
Sound regulations vary by state and province. We offer different sound levels, including our 'Trail' series designed to meet most decibel requirements, and our 'Mountain' series intended for closed-course or off-road use.
