When it comes to classic British sports cars, few models carry the charm and unmistakable presence of the Triumph Stag.
But as many owners know, the right exhaust system is critical to unlocking the car’s true character.
Recently, a Triumph Stag owner visited Paramount Performance seeking a bespoke classic exhaust solution after finding himself underwhelmed by the tone and balance of his existing system.
With its original engine still in place, this Stag represents exactly what classic ownership is about authenticity, heritage, and doing things properly.



The Problem: An Exhaust Note That Didn’t Reflect the Stag’s Character



The vehicle itself was beautifully maintained and mechanically sound. However, the current exhaust system lacked the depth and refinement expected from a classic Triumph V8.
After consulting several Triumph specialists and dealers, the owner was still searching for:
- A deeper, more authentic Triumph Stag exhaust note
- Improved exhaust flow and smoother drivability
- A refined sound without excessive volume
- A solution sympathetic to the originality of the car
Following further research, he discovered Paramount Performance online and our expertise in custom classic car exhaust systems in the UK.
Why Choose a Bespoke Triumph Stag Exhaust?
Unlike modern vehicles, classic cars require a tailored approach.
A Triumph Stag bespoke exhaust system must:
- Respect the engineering of the original vehicle
- Maintain period-correct character
- Improve balance and drivability
- Avoid intrusive drone or harsh resonance
A one-size-fits-all exhaust rarely delivers the correct tone or performance for a heritage vehicle. That’s why we design and fabricate each system around the individual car.
The Paramount Process: Custom Classic Exhaust Fabrication
Every classic exhaust project at Paramount Performance begins with a detailed assessment.
For this Triumph Stag, we:
- Evaluated the existing exhaust system layout and silencer configuration
- Assessed tone characteristics at idle and under load
- Designed and fabricated a fully bespoke exhaust system
Our objective was clear:
Create a custom Triumph Stag exhaust that enhances character without overpowering the car.
Throughout the installation, we documented:
- Before and after imagery
- Fabrication stages
- Final installed system
- A video comparison highlighting the difference in sound
The Result: A Deeper, More Authentic Triumph Stag Exhaust Note




Following installation, the transformation was immediately noticeable.
On startup, the Stag now delivers:
- A deeper, richer V8 tone
- Improved smoothness through the rev range
- Enhanced responsiveness
- A refined, balanced sound profile
Importantly, the system remains sympathetic to the vehicle’s heritage providing a confident exhaust note that feels authentic rather than exaggerated.
For classic cars, refinement matters as much as performance.

Owner Feedback
For us, the most important result is always the owner’s reaction.
Following the installation of the bespoke stainless steel exhaust system, the Triumph Stag’s owner shared:
“Totally professional from start to finish, new stainless exhaust for my Triumph Stag which is superb quality and brought back the true exhaust tone. Very pleased with the result.”
