Powerage Slip-On Exhaust with De-Cat Pipe for Royal Enfield Himalayan 450

The new 450 platform already revs and breathes differently from the old air-cooled Himalayan — this exhaust system is built to let it show. The Powerage Slip-On with De-Cat Pipe replaces the full stock exhaust path, not just the end can, for a genuinely bigger jump in performance and weight savings than a slip-on alone.

Both pieces are crafted from premium stainless steel with precision TIG welding: the slip-on muffler and a high-flow de-cat pipe that opens up exhaust flow further up the system, ahead of the muffler itself. Together they're dyno-tested to deliver a real, measured gain in horsepower, torque, and throttle response — the kind of difference you feel from the first ride, not just read on a spec sheet.

The weight savings are significant: the slip-on weighs approximately 2kg and the de-cat pipe around 1kg, against a stock exhaust system weight of roughly 5.5kg. That's real mass coming off the bike, and on an adventure platform like the 450, less weight there means noticeably sharper handling and agility, on tarmac and off it. A detachable dB reducer keeps the tone in your control — restrained for daily riding, opened up for a deeper, more resonant note when you want it.

Installation is a complete slip-on system — no cutting or welding required — though it's a more involved fit than a muffler-only swap, since it includes the de-cat section. Basic tools and about two hours are typically enough; a torque wrench is worth having on hand.

Important — please read before ordering: a de-cat pipe removes the catalytic converter from your exhaust path. This is an emissions modification, not just a sound one, and is a more serious legal consideration than a standard slip-on under Indian motor vehicle regulations. We'd strongly recommend checking your local rules before fitting this, particularly around PUC/emissions testing. ECU remapping isn't mandatory with this system, but it's recommended for the most consistent performance and fuel efficiency after installation.

Fitment note: this exhaust is designed specifically for the Himalayan 450 and is not compatible with the older Himalayan 411.
