Red Rooster Rumbler Max Polish Exhaust for Royal Enfield Hunter / Meteor / Classic 350 Reborn

The Red Rooster Performance Rumbler Max – Polish (Chrome) is a high-flow, premium exhaust designed specifically for Royal Enfield Hunter 350, Meteor 350 and Classic 350 Reborn (J-Series, BS6) – not a universal silencer. The official RRP product page clearly lists compatibility only with these three models, with Finish: Polish and color options Polish / Black / Matte.

Built from Grade 304 stainless steel (SS304) and packed with advanced ceramic wool, the Rumbler Max Polish is engineered to handle Indian heat and long touring while maintaining back-pressure and flow. RRP highlights a deep, throaty sound, “rust-free durability,” “lightweight build,” and up to 10% increase in engine performance, with a separate FAQ noting up to 10% gain in power and torque and a claimed 20% performance gain in their marketing copy.

At only 2.7 kg, it is significantly lighter than the stock can, improving agility and feel. The high-shine chrome / polished finish gives a factory-plus look that suits Classic Reborn, Meteor and Hunter builds where customers want a clean, premium shine instead of matte or black.

Installation is easy bolt-on on the stock header, with no cutting or welding required. RRP backs the exhaust with a lifetime warranty against rust and manufacturing defects, which is clearly stated in the built-in FAQ on their product page.

If you want your J-Series 350 to look classy, pull harder and sound like a proper Royal Enfield while staying reliable for daily and touring use (DB-killer fitted), the Rumbler Max Polish from Under The Hood is a top-tier, fully verified choice.

Key Features

1. Exact-fit for J-Series 350 only – Official RRP page shows compatibility with Hunter 350, Meteor 350, Classic Reborn 350 and nothing else; 6KIOM and other dealers repeat the same trio.

2. Polished chrome SS304 body – Fabricated from Grade 304 stainless steel, giving a bright chrome-like finish with strong corrosion resistance and long service life.

3. Advanced ceramic wool packing – RRP explicitly mentions advanced ceramic wool construction for higher thermal resistance and smoother power delivery compared with simple glass wool.

4. Deep, throaty Royal Enfield thump – Icon set on RRP page highlights “Deep, Throaty Sound”; tuned to amplify the RE character without being absurdly loud with DB-killer installed.

5. Performance-focused design – Icons + FAQ state up to 10% increase in engine performance / power & torque, and product copy claims a “remarkable 20% gain in performance” for Hunter 350.

6. Lightweight 2.7 kg can – Official specification lists exhaust weight as 2.7 KG, making the bike feel more flickable than with the OE silencer.

7. Rust-free durability – RRP iconography and FAQ stress rust-free construction plus lifetime warranty against rust and manufacturing defects.

8. Direct bolt-on fitment – Installation section clearly states “easy bolt-on installation” onto the existing setup with no major changes needed.

FAQs 

Q1. Will the Rumbler Max Polish fit my old Classic 350 (UCE) or Bullet 350?
No. The Rumbler Max Polish is designed only for the J-Series 349cc platform – Hunter 350, Meteor 350 and Classic 350 Reborn. RRP’s own compatibility line and dealer listings confirm only these three models; it should not be installed on older UCE Classics/Bullets or other REs.

Q2. Do I need an ECU remap after installing this exhaust?
RRP’s FAQ clearly says an ECU remap is not mandatory. Their exhausts are tuned to work safely with the stock map, while a remap or piggyback ECU can be used later if you add intake or engine modifications and want to optimise gains.

Q3. Will my mileage drop with the Rumbler Max Polish?
In the same FAQ block, RRP mentions “No noticeable drop — our exhausts are tuned for balanced power and efficiency.” Real-world mileage will depend more on how aggressively you ride after the upgrade; if you keep a similar riding style, the change in fuel efficiency is usually small.

Q4. Is the RRP Rumbler Max exhaust street-legal in India?
RRP’s FAQ states that their exhausts are not officially street-legal, but they supply a DB-killer to keep sound levels within manageable limits. You should use the baffle on public roads and follow your local RTO regulations at all times.

Q5. What warranty does Red Rooster offer on the Rumbler Max Polish?
The same FAQ confirms a lifetime warranty against rust and manufacturing defects, provided the exhaust is used normally (no cutting/abuse) and registered as per RRP’s warranty process.
