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

The Red Rooster Performance Rumbler Max Black Matte is a dedicated performance exhaust for the new-gen Royal Enfield Hunter 350, Meteor 350 and Classic 350 Reborn (J-Series) – not a universal silencer. On the official Red Rooster site, Rumbler Max – Black clearly lists compatibility as Hunter 350 / Meteor 350 / Classic Reborn 350, with the black finish as one of the three factory options (Polish, Black, Matte).

Built from Grade 304 stainless steel (SS304) and packed with advanced ceramic wool, Rumbler Max is designed to withstand Indian heat, traffic and touring abuse while maintaining consistent back-pressure and exhaust flow. The result is a deep, throaty RE thump, crisper throttle response and a claimed performance gain of up to 10–20% in power and torque versus stock, as highlighted across RRP’s product and FAQ sections.

At only 2.7 kg, the can is significantly lighter than the OE unit, improving agility while keeping build quality premium. A supplied DB-killer (baffle) allows you to tame the sound for daily commutes and long rides yet enjoy a strong, bassy note when you open the throttle.

With lifetime warranty against rust and manufacturing defects directly from Red Rooster, easy bolt-on fitment and proven use across leading retailers (6KIOM, V Gears, MotoModz, Bandidos), the Rumbler Max Black Matte is one of the most trusted upgrades for J-Series 350 owners who want performance + proper Royal Enfield sound without guesswork.

Key Features 

1. Model-specific for J-Series 350 – Official RRP page lists Hunter 350, Meteor 350 and Classic Reborn 350 as the only compatible models; no confusion with older UCE Classics or Bullets.

2. Premium SS304 construction – Fabricated from Grade 304 stainless steel for high corrosion resistance and long-term durability in rain, heat and dusty conditions.

3. Advanced ceramic wool packing – Better thermal resistance and sound control than basic glass wool; maintains tone and performance for longer.

4. Deep, throaty RE thump – RRP highlights “Deep, Throaty Sound” and performance icons on the Rumbler Max page; tuned specifically to keep the classic Royal Enfield character.

5. Up to 10–20% performance gain (claimed) – RRP FAQs state up to 10% increase in power and torque, while the Rumbler Max description itself mentions a “remarkable 20% gain in performance” for Hunter 350.

6. Lightweight 2.7 kg can – Official spec lists the exhaust weight as 2.7 kg, helping the bike feel more flickable than with the heavy stock silencer.

7. Stealthy Black Matte finish – Factory Black finish in a subtle matte look that matches Hunter, Meteor and Classic Reborn styling better than raw chrome in many builds.

8. Bolt-on installation – RRP specifies an easy bolt-on fit onto the stock header with no cutting or welding required; any decent local mechanic can install it.

9. DB-killer included – Ships with removable DB-killer / baffle, so you can tune loudness depending on city, touring or off-road use.

10. Lifetime anti-rust warranty – RRP FAQ confirms lifetime warranty against rust and manufacturing defects on their exhausts, subject to normal use.

FAQs 

Q1. Will this Rumbler Max Black Matte fit my BS4 or old UCE Classic 350 / Bullet 350?
No. Rumbler Max is engineered for the J-Series 349cc platform only – Hunter 350, Meteor 350 and Classic 350 Reborn. It does not fit older UCE Classics/Bullets or BS4 models and should not be installed on them.

Q2. Do I need an ECU remap after installing Rumbler Max?
RRP’s generic FAQ states that a remap is not mandatory; their exhausts are tuned for balanced power and efficiency on stock mapping. A remap or piggyback ECU can help extract full benefit if combined with a free-flow filter or other engine mods, but it is optional.

Q3. Will my fuel efficiency drop?
According to RRP, there is no noticeable drop in mileage when ridden normally since the exhaust is tuned for balance between performance and efficiency. If you ride harder to enjoy the sound, you will naturally see lower km/l.

Q4. Is the Rumbler Max exhaust street-legal in India?
RRP clearly mentions that their exhausts are not officially street-legal, but they supply a DB-killer to keep sound within manageable limits. Always use the baffle on public roads and comply with local RTO regulations.

Q5. What kind of warranty does Red Rooster give on this exhaust?
RRP offers a lifetime warranty against rust and manufacturing defects for their exhausts, subject to warranty registration and normal usage (no cutting, abuse or structural modification).
