Red Rooster Performance Rumbler Max Slip-On for Royal Enfield Hunter/ Meteor 350 - RRPRMB/ RRPRMM/ RRPRMP

The Red Rooster Performance (RRP) Rumbler Max series is a versatile, high-bass exhaust system designed specifically for the Royal Enfield J-Series platform.

 

While it is the only Red Rooster option available for the Hunter 350 (due to its unique mounting), it is also a popular "maximum sound" choice for Meteor 350 and Classic 350 Reborn owners.

 

Variant Codes & Aesthetics

The performance and internal construction are identical across all three; the choice is purely down to the look of your bike:

• RRPRMB (Black Matte): A "murdered-out" ceramic finish. It's the top seller for the Hunter 350 Metro and Meteor 350 Fireball series to match the blacked-out cycle parts.

• RRPRMM (Matte Silver): A brushed stainless steel look. It’s excellent for hiding minor scratches and road grime, offering an industrial, modern feel.

   

• RRPRMP (Polish Chrome): A mirror-finish chrome. This is the classic choice for the Meteor 350 Supernova or Classic 350 Reborn to maintain that heritage shine.

Sound Character: The "Loudest" RRP Option

Among the Red Rooster lineup for the 350cc J-Series (which includes the Polestar and Polestar Pro), the Rumbler Max is specifically tuned for the deepest bass and highest volume.

 

• With DB Killer: A rich, chest-thumping bass that is authoritative but usually manageable for city commuting.

   

• Without DB Killer: Very aggressive and loud; ideal for those who want a "big bike" presence, though it may attract unwanted attention from authorities in strict zones.

Fitment & Installation

• Compatibility: Hunter 350, Meteor 350, and Classic 350 Reborn (all 2020+ J-Series models).

   

• Installation: It is a direct bolt-on (slip-on) system. You do not need to cut the header pipe or perform any welding.

   

• ECU Remap: Not mandatory. The stock ECU is capable of compensating for the increased flow, though pairing it with a BMC Air Filter (FM01138) is a common "Stage 1" upgrade for even smoother throttle response.

   

Warranty Note: Red Rooster provides a lifetime material warranty against rust and manufacturing defects. However, always check with your local dealership regarding how an aftermarket slip-on affects your specific vehicle service warranty.
