Performance Exhausts for Honda CB350 Motorcycles
The Honda H'ness CB350 and CB350RS are built for refined, quality-conscious riders who appreciate smooth power delivery and understated engineering. The stock exhaust on both is deliberately quiet — well-made, but muted. A performance slip-on transforms the CB350's character, giving it a fuller, more engaging note without losing the Honda refinement that riders chose the bike for.
At Rawtorque, we stock genuine exhaust options from Red Rooster Performance, Barrel, and other proven brands for the Honda CB350 range, with fitment guidance for both the H'ness and CB350RS variants.
Slip-on vs Full System for Honda CB350
- Slip-on — Replaces the muffler only. The most popular choice for CB350 riders — a clear sound improvement, meaningful tail weight saving, and straightforward bolt-on fitment. Works well as a standalone upgrade.
- Full System — Header-back replacement. The biggest gains in flow and weight. Pairs well with a high-flow air filter and a FuelX module as a complete Stage 1 kit for the CB350's 348cc single.
By Model
Honda H'ness CB350
The H'ness CB350's 348cc single has a refined, quiet stock exhaust note. A Red Rooster or Barrel slip-on gives the H'ness a warmer, more characterful tone — deeper and richer without becoming harsh or unrefined. It matches the modern-classic character of the H'ness better than any other single upgrade. For the full Stage 1, pair with a BMC or NGage air filter and a FuelX module.

Honda CB350RS
The CB350RS shares the H'ness engine in a sportier, neo-retro package. A performance exhaust on the RS brings out its spirited character — a fuller note and lighter tail that suits the RS's more aggressive stance. Many H'ness exhaust options also fit the RS (check the product listing for confirmed fitment).

Completing a Stage 1 for Your Honda CB350
An exhaust alone on a Honda CB350 is a worthwhile upgrade. For measurable performance gains, it works best as part of a three-part Stage 1 setup: BMC or NGage air filter + FuelX Lite or Pro+ fuel controller + performance exhaust. The FuelX compensates fuelling automatically for the freer exhaust flow, and all three parts work together for a stronger, more engaging CB350.

Frequently Asked Questions
Do H'ness CB350 and CB350RS share the same exhaust fitment?
They share the same 348cc engine platform, so many exhaust options fit both. However, check the product listing for confirmed fitment — some slip-on designs are shaped differently for the H'ness versus the RS's bodywork.
Will a CB350 slip-on improve performance or just sound?
A slip-on primarily improves sound and tail weight. For measured performance gains, pair it with an air filter and FuelX module to complete a Stage 1 — the three parts together deliver a real improvement in throttle response and midrange pull.
Do I need a fuel tuner with a Honda CB350 exhaust?
For a slip-on, the stock CB350 ECU generally copes without tuning. For a full system, a FuelX Lite is recommended to keep the fuelling balanced with the improved exhaust flow.
