NORIFUMI Noctus T5 Boreup Exhaust for Hero XPulse 210 — with DB Killer

A bored-out XPulse engine moves more air and needs an exhaust tuned to match — running a stock-tuned pipe on a bore-up build leaves real performance on the table. The Noctus T5 Boreup is built specifically for that scenario: XPulse engines running larger-bore pistons, where the exhaust needs to scavenge more volume without choking the gains you just paid for.

Construction is genuinely serious for the segment: mandrel-bent, high-grade stainless steel throughout, with a free-flowing mid-pipe and a straight-through silencer design that maximizes exhaust scavenging. The result is crisper throttle response, stronger low-end torque, and noticeable gains in peak power — specifically tuned for the demands of an enlarged-bore engine rather than a generic slip-on. The compact canister houses a threaded, removable DB killer, giving you real on-the-fly control over volume and tone — dial it down to a tight, race-ready bark for trail days, or back it off to a deeper, more subdued rumble for daily street riding.

Finished in brushed stainless with subtle Norifumi branding, the T5 Boreup slips on using the supplied clamp and mounting hardware — no cutting or welding required, keeping installation quick and hassle-free.

Important fitment note: this exhaust is built for XPulse engines with a bore-up kit already fitted. If your customer's XPulse is still on the stock engine, this is not the right exhaust for them — point them to the standard Noctus T5 instead.
