Norifumi Whoops SS Slip-On Exhaust for Royal Enfield Himalayan 450 – Short (EXH18155) & Long (EXH18157)

The Himalayan 450's OEM exhaust was always the weakest link. The Norifumi Whoops SS fixes that.

The Norifumi Whoops SS is a stainless steel slip-on exhaust for the Royal Enfield Himalayan 450 — available in Short and Long configurations. The Whoops canister is Norifumi's benchmark adventure exhaust: purpose-built for bikes that go off the road, with stainless steel construction, a bolt-on link pipe, and a sound profile that suits the Himalayan's character without being intrusive.

The Short version offers a cleaner, tucked fitment with slightly less visual presence — ideal for rack-and-luggage setups. The Long version delivers a more substantial canister with additional sound and character.

What's in the box:

• Whoops SS canister (stainless steel)
• Stainless steel link pipe
• All fitment hardware (brackets, clamps, heat shield)

Why Norifumi Whoops SS:

• Weight reduction: Meaningfully lighter than the OEM canister and mid-section
• Better flow: Improved exhaust scavenging — sharper throttle response
• Adventure-ready construction: Stainless steel — built for the conditions the Himalayan is designed for
• Two length options: Short for luggage-carry setups, Long for maximum presence
• Genuine Norifumi: Authorised distributor stock, MRP inclusive of 18% GST

Compatible Bike: Royal Enfield Himalayan 450 (2024 onwards)
