---tab FAQ---

Q1. What’s the difference between 4" and 5" exhaust systems?

• 4" – Better for mild/moderate tunes, retains some backpressure for low-end torque.
• 5" – Best for high-horsepower builds, maximizes flow for reduced EGTs and top-end power.

Q2. Will a magnet stick to this pipe? Is it really stainless steel?

Yes – This pipe uses T-409 stainless steel, which is still magnetic (unlike T-304). It offers excellent corrosion resistance while being more affordable than T-304.

Q3. How thick is the pipe? Will it last?

2mm thick T-409 stainless steel – Durable enough for long-term use without excessive weight.

Q4. Is this a full turbo-back or just downpipe-back?

• Downpipe-Back – Replaces everything after the downpipe (DPF & exhaust).
• For a full turbo-back system, you’ll need an additional DPF-delete downpipe.

Q5. Will this improve performance?

• Yes! Benefits include:
• Lower EGTs (Exhaust Gas Temperatures)
• Faster turbo spool
• Better fuel efficiency (with proper tuning)
• No more DPF clogging issues

Q6. Is this street legal?

⚠ Off-Road Use Only – DPF removal is illegal for on-road vehicles in most regions. For competition/racing use only.
