Description
Unlock the Guerrilla 450’s true character with the Powerage Slip-On Exhaust with De-Cat Pipe for Royal Enfield Guerrilla 450 — a performance-focused system designed to improve throttle response, mid-range torque, and exhaust tone without compromising everyday usability.
This isn’t just a louder muffler. It’s a carefully engineered slip-on and de-cat combination that allows the Royal Enfield Guerrilla 450 to breathe more freely. By reducing exhaust restriction and optimizing gas flow, the system sharpens throttle pickup and makes the single-cylinder engine feel more responsive across the rev range.
Engineered for Better Flow
The included model-specific de-cat pipe replaces the restrictive catalytic section, improving exhaust scavenging and reducing excess heat build-up near the engine. With smoother flow characteristics, the Guerrilla 450 responds quicker when you roll on the throttle.
The freer breathing setup enhances mid-range pull — the rpm band where riders spend most of their time. Whether you’re navigating city traffic or accelerating out of highway bends, the improvement feels clean and progressive rather than abrupt.
Slip-On Design – Direct Bolt-On Fit
The Powerage Slip-On Exhaust for Royal Enfield Guerrilla 450 is designed as a direct replacement for the stock muffler assembly. No cutting. No welding. No fabrication.
Installation remains straightforward:
Remove the factory exhaust
Install the Powerage slip-on
Fit the supplied de-cat pipe
Secure with provided mounting hardware
No ECU remap is required for installation. The system is engineered to work within stock fueling tolerances under standard riding conditions.
Stainless Steel Construction
Both the slip-on unit and the de-cat pipe are manufactured using high-grade stainless steel. This ensures strength, corrosion resistance, and improved heat durability for long-term use.
Stainless steel also provides structural integrity without unnecessary bulk. Compared to the stock exhaust, this setup reduces overall exhaust mass, contributing to a slightly lighter rear profile and more agile handling feel.
Approximate weights:
Slip-On Exhaust: ~2 kg
De-Cat Pipe: ~1 kg
This weight reduction improves balance while maintaining durability for daily riding and touring applications.
Sound Profile – Deep, Clean, Controlled
The Powerage Slip-On Exhaust for Guerrilla 450 delivers a deeper, more pronounced exhaust note compared to the stock muffler. The tone is fuller and more muscular, complementing the character of the 450cc single-cylinder engine.
The sound profile remains controlled rather than harsh. It enhances presence without turning the motorcycle into an overly loud setup. Ideal for riders who want a noticeable upgrade in tone without compromising ride comfort.
Performance Character
With the de-cat pipe improving flow and the slip-on reducing back-pressure, riders can expect:
• Cleaner throttle pickup
• Sharper mid-range response
• Improved engine breathing
• Reduced exhaust heat concentration
• A more engaging riding feel
This system does not claim peak horsepower figures or dyno numbers. Instead, it focuses on real-world rideability improvements that are noticeable in everyday riding scenarios.
Built for Everyday Use
The Powerage Slip-On + De-Cat System for Royal Enfield Guerrilla 450 is designed for daily commuting, highway touring, and spirited weekend rides.
It maintains structural durability under heat cycles and vibration. Stainless construction ensures resistance against rust in humid and mixed riding conditions.
This is a performance-oriented upgrade that balances usability and mechanical simplicity.
