NORIFUMI Slip-On GTX Exhaust for Royal Enfield Interceptor 650 — Stainless Steel

The Interceptor 650's parallel-twin has one of the best factory soundtracks in its class — the GTX doesn't fight that character, it sharpens it. This is Norifumi's flagship offering for the 650 twin, built with the same race-honed engineering as the rest of their range but tuned for a refined, premium road bike rather than a dirt track.

Constructed entirely from premium stainless steel, the GTX delivers genuine durability and corrosion resistance alongside a real reduction in weight over the stock system. Exhaust flow is engineered for measurable gains in horsepower and torque, translating into a noticeably smoother, more responsive ride whether you're cruising the highway or working through a set of twisties. The note is tuned to be aggressive without losing refinement — a deeper, more purposeful voice for the twin, not just louder for the sake of it. The sleek slip-on silhouette adds a sporty, premium edge to the Interceptor's classic roadster lines.

It's a direct slip-on fit — bolts onto the stock header with no cutting or welding required.

Worth knowing before you fit one: aftermarket exhausts change your bike's stock noise output, and Indian motor vehicle rules regulate permissible noise levels. Most riders fit slip-ons without issue, but it's worth being aware of your local regulations, particularly around PUC testing, before modifying your exhaust.
