Kia Stinger GT 3.3L Twin Turbo V6 – 2.5" Cat-Back Performance Exhaust

Looking to upgrade the exhaust on your Kia Stinger GT 3.3L Twin Turbo V6? Rhino Exhaust offers a 2.5-inch cat-back performance exhaust system designed to deliver improved exhaust flow, a more aggressive exhaust note and an enhanced driving experience.

Designed for compatible Kia Stinger GT models manufactured between 2017 and 2023, the Rhino Exhaust system replaces the factory cat-back exhaust assembly with mandrel-bent stainless steel pipework and straight-through Megaflow performance mufflers.

The system features direct bolt-on installation using the factory exhaust flange connections and mounting positions.

The rear muffler outlets are designed to retain the original Kia Stinger bumper-mounted exhaust tips, maintaining the vehicle's distinctive factory appearance while delivering a more pronounced performance exhaust sound.

Why Upgrade Your Kia Stinger GT Exhaust?

The Kia Stinger GT is powered by a 3.3L twin-turbocharged V6 petrol engine, combining strong performance with the practicality and comfort of a grand touring sedan.

While the factory exhaust is designed to balance performance, noise levels and everyday refinement, many Stinger owners prefer a more distinctive exhaust note that better complements the vehicle's performance characteristics. Upgrading to the Rhino Exhaust 2.5-inch cat-back system provides a performance-oriented alternative to the original exhaust configuration.

Benefits can include:

• Improved exhaust flow through 2.5-inch mandrel-bent pipework.

• Reduced exhaust flow restrictions compared with restrictive factory components.

• A deeper, more aggressive exhaust note.

• Straightforward direct bolt-on installation using factory mounting positions including retention of the original OEM bumper-mounted exhaust tips.

• A performance exhaust upgrade without requiring replacement of the factory catalytic converters.

Actual performance improvements will depend on vehicle condition, factory exhaust configuration and any existing modifications.

Stainless Steel Cat-Back Exhaust System

The Rhino Exhaust Kia Stinger GT system incorporates 2.5-inch mandrel-bent exhaust pipework designed to maintain a consistent internal diameter through bends and support efficient exhaust gas flow.
Unlike conventional press-bent pipework, mandrel bending helps preserve the internal cross-sectional area of the exhaust through curved sections, reducing unnecessary restrictions.

The design includes a centre assembly with a twin-inlet/twin-outlet muffler, connecting pipes and left- and right-hand rear muffler assemblies. The straight-through Megaflow mufflers are designed to balance efficient exhaust flow with a more distinctive performance exhaust sound.

Constructed from polished 409-grade stainless steel, the system offers corrosion resistance and durability for everyday road use.

Kia Stinger GT Exhaust Sound – What to Expect

For many Kia Stinger GT owners, exhaust sound is one of the primary reasons for upgrading the factory system.
The Rhino Exhaust cat-back system is designed to deliver a deeper and more pronounced exhaust note, allowing more of the 3.3L twin-turbo V6 engine's character to be heard during acceleration.

The straight-through muffler configuration provides a sportier sound compared with the original factory exhaust arrangement which is a triple flow design restricting exhaust flow and sound.

Exhaust volume and tone can vary depending on engine speed, driving conditions, vehicle model year and any additional exhaust modifications. For customers comparing aftermarket Kia Stinger exhaust systems, we recommend listening to the video clip of the Rhino Exhaust system here before purchasing.

Kia Stinger GT Factory Bimodal Exhaust Compatibility

Some later-model Kia Stinger GT vehicles feature a factory bimodal exhaust system, allowing the exhaust sound to be adjusted through electronically controlled exhaust valves. The Rhino Exhaust 2.5-inch cat-back system replaces the original rear muffler assemblies and does not retain the factory bimodal exhaust functionality.

Once installed, the exhaust operates with a fixed muffler configuration rather than switching between the factory exhaust sound modes. This is an important consideration for owners of later-model Stinger GT vehicles who are comparing conventional performance exhaust systems with electronically valved alternatives.

Direct Bolt-On Installation and Factory Exhaust Tip Compatibility

The Rhino Exhaust Kia Stinger GT cat-back system is designed to connect directly to the compatible factory exhaust flanges and utilise the original exhaust hanger positions.

The system is supplied with gaskets and fitting hardware to assist with installation. Importantly, the rear exhaust outlets are designed to align with the original Kia Stinger bumper-mounted exhaust tips, allowing the factory exterior appearance to be retained without modification to the bumper-mounted tip assemblies.

Installation by a qualified mechanic or exhaust specialist is recommended to ensure correct exhaust alignment, sealing and clearance from surrounding components.

Frequently Asked Questions

Will this exhaust fit my Kia Stinger GT 3.3L Twin Turbo?

The Rhino Exhaust 2.5-inch cat-back system is listed for compatible Kia Stinger GT models equipped with the 3.3L twin-turbocharged V6 petrol engine, manufactured between 2017 and 2023.
Customers should confirm vehicle compatibility, particularly for different international-market specifications and later-model factory bimodal exhaust configurations.

Is International Shipping Available? 

As the Kia Stinger GT is sold globally, Rhino Exhaust regularly receives enquiries from international customers and offers worldwide shipping.

If you're considering purchasing from outside Australia, please email info@rhinoexhaust.com.au with your full shipping address and vehicle details so we can confirm compatibility and provide a quotation inclusive of international airfreight.

Will the Rhino Exhaust system make my Kia Stinger louder?

Yes. The Rhino Exhaust system is designed to deliver a more pronounced and aggressive exhaust note than the factory exhaust.
The straight-through Megaflow mufflers allow more of the engine's natural exhaust sound to be heard, particularly during acceleration.

Does the Kia Stinger cat-back exhaust produce cabin drone?

The Rhino Exhaust system has been designed to minimise unwanted cabin resonance. This is achieved through the use of densely packed sound-absorbing material within the Megaflow mufflers, helping manage unwanted exhaust frequencies while retaining a straight-through internal design for efficient exhaust flow.

The resulting cabin sound will depend on engine speed, driving conditions and any additional vehicle modifications.

Will the Rhino Exhaust system improve horsepower and torque?

The 2.5-inch mandrel-bent system is designed to improve exhaust flow and reduce unnecessary restrictions.
A less restrictive exhaust can support engine performance, although actual horsepower and torque improvements depend on the vehicle's configuration and other modifications. Specific performance gains are not guaranteed.

Does this exhaust retain the factory bimodal exhaust function?

No. The Rhino Exhaust system does not retain the electronically controlled bimodal exhaust functionality fitted to certain later-model Kia Stinger GT vehicles.
The replacement exhaust operates with a fixed muffler configuration.

Will the factory Kia Stinger exhaust tips still fit?

Yes. The Rhino Exhaust rear muffler outlets are designed to accommodate the original bumper-mounted Kia Stinger exhaust tips, retaining the factory rear bumper appearance.

Does installing a cat-back exhaust require an ECU tune?

A conventional cat-back exhaust upgrade does not generally require an ECU remap because it replaces exhaust components downstream of the factory catalytic converters.

What is the difference between a cat-back exhaust and a turbo-back exhaust?

A cat-back exhaust replaces the exhaust system downstream of the catalytic converters, while retaining the factory catalytic converters and upstream exhaust components.
A turbo-back exhaust is from the turbocharger outlets and involves replacement of the down pipes and catalytic converters.

What warranty does the Rhino Exhaust Kia Stinger exhaust include?

The Rhino Exhaust Kia Stinger GT 2.5-inch cat-back performance exhaust is supplied with a three-year warranty, subject to the applicable warranty terms.
