The Lexus RC350 XC10 V6 3.5 exhaust in detail.
A clear, almost mechanical voice that tightens as the revs rise and becomes downright furious at the top of the rev counter: the RC350’s 3.5-litre naturally aspirated V6 has a sound that has become rare since turbocharging took over. The factory exhaust smothers precisely the best part, that final climb reduced to a discreet hum.
With dual injection, both direct and port, this V6 develops 310 hp and 376 Nm, with progressive power delivery and precise throttle response. The page covers the XC10 coupé from 2014 to 2021, excluding the RC300 and later model years; the RC200t and RC F have their own pages, and your VIN is checked before manufacturing.
With the valves open, the Rog valved cat-back lets the V6 express itself every time the revs rise, hoarse low down then sharp and clean towards the red line; with the valves closed, the RC350 regains the hushed refinement that Lexus is known for. No welding for fitting: clamps, gaskets and about two hours, with the factory valve control if it exists, the Rog remote otherwise.
No front section is sold on this page: the system connects behind the factory catalytic converters, with no ECU remap, and the V6 keeps its 310 hp. You choose the material of the round tips: 304 stainless steel for toughness and a full sound, or titanium, around 40% lighter, available in brushed, gold or purple.

Questions about the Lexus RC350 XC10 V6 3.5 exhaust.
Can a Lexus RC300 take the RC350 V6’s exhaust?
No, the RC300 is not covered by this page, nor are model years after 2021. This one targets the 2014 to 2021 RC350 XC10; if in doubt, your VIN lets us check before manufacturing.
Does the RC350’s V6 3.5 require an ECU remap with the Rog system?
No: with no front part, the system fits behind the original catalytic converters and leaves the map as it is. On this naturally aspirated V6, people come for the voice, the breathing and a little lightness.
Lexus RC350 XC10 V6 3.5 with a Rog exhaust: what should you know about vehicle inspection?
The configuration lends itself to it, without promising anything: with the valves closed, the V6 regains stock discretion, and the original catalytic converters stay in place since this page does not replace them.
Does the RC350 V6 with a Rog system drone on long journeys?
No, with the valves closed: the cabin keeps the calm of a Lexus, even at a steady speed. The V6’s furious climb returns at your request, via the factory control or the Rog remote.
Lexus RC350 XC10 V6 3.5: straight pipe or resonator?
On this model, two characters at the same price: the straight pipe for the raw sound of your engine, unfiltered, or the resonator for a rounder and slightly softer voice. Either way, the exhaust stays fully sporty. Learn more: Exhaust resonator: what does it do? Straight pipe or resonator, which sound to choose.
