Hellfire Fabrication now produces limited quantity batches before opening up for monthly drops rather than the old 'built to order' method. This reduces the feared fabrication wait times and increases the speed at which orders will ship.
Clients are still able to select their preferred setup while inventory lasts per month.
Once a configuration or option sells out, it will remain unavailable until a future production drop.
Processing and shipping times may vary depending on demand, holidays, weekends, carrier delays, and other factors outside of our control.
Feel free to contact Hellfire Fabrication by email with questions regarding fitment, special applications, or shipping costs.

INSTALLATION REQUIREMENTS
If you plan on installing with OEM header, you may need to slightly bend driver side heat-shield which can easily be done with pliers. This will prevent any potential for contact. Removing the heat-shield on OEM header closest to j-pipe is an option as well. Modification to the bumper and plastic shielding under-tray will be required.
Additional modification may be required depending on vehicle trim level and existing aftermarket components.
Note: Adjustments may need to be made post install at the vband and mounting point to ensure system does not contact transmission brace or other components. For static low suspension setups with minimum to no ground clearance, the HfF Side Exit exhaust is highly recommended.
Potential interference areas may include:
- Fog lights
- Wheel well liners
- Windshield washer fluid reservoir
- Aftermarket piping
- Other components occupying the Side Exit routing area
TUNING WARNING
Installation of a Cut Out Kit without proper tuning, re-tuning, or tuner consultation may result in vehicle damage.
Some tuners may recommend checking for overboost before determining whether additional tuning is required.
Tuning methods vary. Always consult your tuner before operating the vehicle after installation.
Hellfire Fabrication is not a tuning company and cannot provide tuning advice.
CARE
Exercise caution while washing a vehicle equipped with a Side Exit Exhaust.
Avoid spraying water directly into the exhaust outlet.
LIABILITY
Hellfire Fabrication will not be held liable for damage resulting from improper installation, negligence, improper tuning, inadequate clearance, or incompatibility with existing aftermarket components.
RETURNS
Returns will not be accepted if the exhaust has been installed, used, modified, altered, or damaged in any way.
Because Cut Out Kits are produced in limited production drops and configured from available inventory, customers are responsible for confirming fitment, compatibility, and selected options before placing an order.
Please order only after confirming that the selected configuration is correct for your vehicle and intended application.
Hellfire Fabrication prioritizes quality over quantity and will never sacrifice quality to rush production and fulfill quantity/timeline demands.
Each production batch is hand fabricated, inspected, and prepared for release in the United States before fulfillment.
