Choosing Your Setup

• OEM Style: Closest to factory refinement with improved flow and subtle sound enhancement.
• Single Midpipe (Resonated): More controlled tone with reduced harshness and deeper character.
• Single Midpipe (Non-Resonated): Louder, more aggressive and raw exhaust sound.
• Equal Length (Resonated): Smooth, balanced and refined tone across the rev range.
• Equal Length (Non-Resonated): Sharper, more aggressive sound with increased presence.
• 3D Z-Pipe Equal Length: Higher pitched, more exotic tone inspired by motorsport setups.

Sound Selection Guide: OEM Style offers a more balanced factory-like character, Single Midpipe creates a louder and more raw exhaust sound, Equal Length delivers a smoother and more refined tone, and 3D Z-Pipe Equal Length produces a higher pitched and more exotic sound profile.

Sound characteristics vary significantly depending on selected midpipe configuration.
