📌 Exhaust Builder Pro – All Sliders Fully Functional! Exhaust Builder Pro is now fully functional with complete real-time control over engine and exhaust sound behavior. Every node in the system (Engine, Header, Pipe, Muffler, H/X) has working sliders that directly affect the sound physics.

🔧 ENGINE BOX – Core Engine Sound Control

Controls the fundamental combustion and firing behavior.

Engine Type (Inline / V) Defines engine layout and bank structure.

Cylinders (4–12) Affects firing frequency, pulse density and overall tone.

Displacement (1.0–8.0 L) Controls low-end energy, exhaust mass and sound pressure.

V Angle (for V engines) Controls bank phasing and pulse spacing (60°, 72°, 90°, 120°, 180°).

V8 Type (Cross / Flat) Changes pulse clustering and characteristic V8 sound behavior.

Valvetrain (SOHC / DOHC) Affects high-frequency response and valve flow character.

🔥 HEADER BOX – Primary Exhaust Character

Defines the raw exhaust tone and pulse structure directly at the engine.

Header Type (6-2-1 / 6-1) Controls torque-style vs race-style sound character.

Material (Cast / Steel / Stainless / Titanium / Inconel) Affects heat, ring, damping and metallic brightness.

Bends More bends = more turbulence, less harmonic purity.

Header Length (cm) Directly shifts resonance, pulse timing and scavenging behavior.

🛣️ PIPE BOX – Mid Exhaust Behavior

Controls how exhaust waves travel through the system.

Pipe Material Controls damping and surface reflection.

Pipe Diameter (cm) Affects flow speed, loudness and frequency spread.

Pipe Length (cm) Controls boom, echo timing and wave interference.

🔇 MUFFLER BOX – Final Sound Attenuation

Controls real physical sound damping and filtering.

Muffler Material Affects absorption, heat loss and tonal softness.

Attenuation (%) Directly controls how much volume and high frequencies are reduced.

Multiple mufflers are summed in real time.

Muffler Length (cm) Affects low-mid bloom and overall exhaust depth.

🔁 H / X PIPE H-Pipe – classic balance tube, smoother low-end.

X-Pipe – sharper crossover, more high-RPM clarity.

✅ What’s New in This Version
