Confidence

Strong fitment evidence and multiple consistent owner sound references; dB figures are owner-measured rather than lab-verified.

Recommended setup

Slip-on muffler + baffle, stock header

$350–$600
slip oneasy installtune recommendedhigh fitment

A quality slip-on deepens the CP2 character without the loudness or tune demands of a full system.

Why it matches · The CP2 crossplane twin already has a deep pulse. A slip-on amplifies low-end bark while a removable baffle keeps highway cruising civil.

Quality slip-on with baffle

Deepens tone, keeps it street-legal-ish with the baffle in.

Sound · Deep, restrained, civil on the highway

Tradeoffs · Less top-end aggression than a full system

balanced$500–$750

Slip-on + fuel tune

Slip-on paired with a flash tune for crisp throttle and fuller mid-range.

Sound · Deep with sharper acceleration bark

Tradeoffs · Adds tune cost; slightly louder

premium$900–$1,400

Full system + tune

Header-back system for maximum character and a modest power bump.

Sound · Loud, raw, track-leaning

Tradeoffs · Loudest; tune required; highway drone risk rises

Sound expectation
Idle
Low, lopey thrum with a noticeable pulse.
Acceleration
Deep bark that hardens past 6k rpm.
Deceleration
Light, controlled pops with the baffle in.
Highway
Present but not fatiguing at 70–80 mph cruise.
Install checklist

  • Flash a fuel tune

    Recommended for crisp throttle response.

  • Re-torque clamps after first heat cyclerequired

    Prevents slippage and leaks.
