Norifumi Whoops SS Carbon Slip-On Exhaust for Royal Enfield Himalayan/Guerrilla 450 – Short (EXH18156) & Long (EXH18158)

All the Whoops SS — with a carbon fibre end cap. Same Himalayan-ready build, sharper finish.

The Norifumi Whoops SS Carbon is the carbon end-cap variant of the Himalayan 450 Whoops slip-on — stainless steel canister body with a carbon fibre exit cap for a premium visual finish. Available in Short and Long configurations. Everything else is identical to the Whoops SS: stainless steel link pipe, complete fitment hardware, and Norifumi's characteristic adventure-tuned sound profile.

The Short version sits tighter to the bike — better for luggage and pannier setups. The Long version has a more commanding canister profile and deeper note.

What's in the box:

• Whoops SS Carbon canister (stainless body + carbon fibre end cap)
• Stainless steel link pipe
• All fitment hardware (brackets, clamps, heat shield)

Why Norifumi Whoops SS Carbon:

• Carbon end cap: Premium finish over the standard Whoops SS — same performance, better aesthetics
• Weight reduction: Lighter than OEM canister and mid-section assembly
• Better flow: Improved exhaust scavenging vs. stock
• Stainless + carbon build: Durable in the conditions the Himalayan rides in
• Genuine Norifumi: Authorised distributor stock, MRP inclusive of 18% GST

Compatible Bike: Royal Enfield Himalayan 450 (2024 onwards)
