If the Noctus T5 Boreup is the sensible upgrade, the Rocket 4 Kompetisi is the one for riders chasing every last bit of performance.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"15:1-15:685;649-1333\"\u003eMandrel-bent, high-grade stainless steel piping feeds a free-flowing mid-pipe and straight-through muffler, tuned specifically to maximize scavenging on bored-up setups — sharper throttle response, stronger low-end torque, and a genuine gain in peak power where a standard pipe would start choking the extra displacement. The compact, competition-style silencer carries a precision-machined end cap and a slash-cut tip, with a removable DB killer letting you switch between a tight, track-ready growl and a deeper, more street-appropriate rumble. Brushed steel finish with laser-etched Norifumi branding rounds off a genuinely motorsport-grade look, not just a motorsport-grade claim.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"17:1-17:110;1335-1444\"\u003eInstallation is a bolt-on slip-on fit using the included clamp and mounting hardware — no cutting or welding.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"19:1-19:256;1446-1701\"\u003e\u003cstrong\u003eImportant fitment note:\u003c\/strong\u003e the Rocket 4 Kompetisi is tuned for bore-up XPulse engines, same as the Noctus T5 Boreup — it is not the right pipe for a stock-engine XPulse.
