Frequently Asked Questions
Does the B1501-C1501 fit my 2020 Kia Stinger GT 3.3T?
Yes. The B1501-C1501 fits 2018-2021 Kia Stinger GT models with the 3.3T twin-turbo V6 engine.
Does this fit the Kia Stinger GT2 or GT-Line?
The B1501-C1501 is designed for the 3.3T twin-turbo V6 Stinger GT. If you have a GT2 with the 3.3T, this system will fit. The GT-Line and lower trim Stingers use a different 2.0T four-cylinder and require a different exhaust system. Contact us to confirm fitment before ordering.
How does the B1501-C1501 integrate with the factory tips?
The Kia Stinger GT has built-in tips integrated directly into the rear bumper valance. The B1501-C1501 is engineered to mate directly with the factory tip inlets in the rear valance, preserving the clean OEM factory appearance with improved exhaust flow and sound.
Will there be highway drone?
No. True Helmholtz Technology targets and reduces the resonance frequencies responsible for cabin drone at highway cruising speeds. The B1501-C1501 delivers a more aggressive exhaust note during acceleration while remaining comfortable at 65 to 80 mph.
Does installation require cutting or welding?
No. The B1501-C1501 is a complete bolt-on catback system. All hardware and clamps are included. No cutting, welding, or drilling is required.
Does this also fit the 2022 or newer Kia Stinger?
The B1501-C1501 is designed for the 2018-2021 Stinger GT 3.3T. Contact us to verify fitment on 2022 and newer Stinger models before ordering.
How much deeper is the exhaust note compared to stock?
Noticeably deeper and more aggressive during acceleration. The 3.3T twin-turbo V6 responds well to the improved flow, and the True Helmholtz design keeps the sound premium rather than harsh or droning at highway speed.
What warranty does the B1501-C1501 carry?
Thermal R&D covers this system with a Limited Lifetime Warranty to the original vehicle owner, non-transferable. The warranty covers defects in materials and workmanship and does not apply to racing, commercial use, or improper installation. Manufactured in Lancaster, California.
Installation Instructions
Allow the vehicle exhaust to cool fully before beginning. Raise the vehicle safely on jack stands. Working from rear to front, carefully disconnect the OEM catback at the factory mid-pipe to catback joint. Remove the factory catback system from all hanger locations. Install the B1501-C1501 starting at the rear section, leaving all clamps hand-tight. Route the system into all OEM hanger locations, ensure proper alignment with the factory rear valance tip inlets, and torque all clamps to specification. Start the engine and check all connections for leaks before returning to service.
