APEXI FULL EXHAUST SYSTEM FOR SUBARU BRZ ZD8 TOYOTA GR86 ZN8 MT FA24 143-T004J

🧠 What makes this system special

• Full exhaust (header → front pipe → muffler)
  Not just sound — this is a performance package, unlike typical bolt-on cat-backs.
• 4-2-1 exhaust manifold design
  Improves mid-range torque, fixing the FA24’s natural dip  
• Super Catalyzer (130 cpsi)
• Lower restriction vs OEM
• Still maintains emissions performance
• Better flow + usable power gains  
• Optimized piping layout (up to 60mm)
  Ensures smooth exhaust velocity from headers to rear  
• Titanium tail + high-grade finish
  Premium JDM aesthetics + weight reduction

🔊 Sound Profile

• Around ~92 dB (noticeably loud but not insane)  
• Tone:
• Deep boxer rumble
• Strong mid/high RPM aggression
• Less “raspy” vs cheap headers
• Expect:
• Loud cold start
• Track-ready presence (not “quiet daily” spec)

⚙️ Performance Gains (Realistic Expectation)

This is where it shines:

• ✅ Stronger mid-range torque (biggest gain area)
• ✅ Improved throttle response
• ✅ Better top-end breathing
• ⚠️ Requires ECU tune to unlock full potential

👉 Compared to cat-back only systems:

• Cat-back = sound + minor gains
• This full system = real performance upgrade

⚠️ Important Notes

• ❌ Manual (MT) only – not compatible with AT  
• ⚠️ Expensive (usually RM 6k–10k+ landed)
• ⚠️ Install complexity higher (headers + cat involved)
• ⚠️ May not pass strict inspection without proper tuning/cat compliance

💡 Verdict (Straight Talk)

• If your goal is real performance + race-inspired setup → this is top-tier
• If your goal is just sound + daily comfort → overkill

👉 This is the kind of system you buy when:

• You plan headers + tune
• You want complete exhaust flow optimization
• You’re building a serious NA FA24 setup
