FAQs
Q. What’s the difference between 4" and 5" exhaust systems?
A: 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.
Q. Will a magnet stick to this pipe? Is it really stainless steel?
A: 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.
Q. How thick is the pipe? Will it last?
A: 2mm thick T-409 stainless steel – Durable enough for long-term use without excessive weight.
Q. Will this improve performance?
A: Yes! This DPF delete exhaust will lower your EGTs (exhaust gas temperatures), speed up the turbo spool, which in result gives you better fuel efficiency.
Q. Is this street legal?
A: Off-Road Use Only – DPF removal is illegal for on-road vehicles in most regions. For competition/racing use only.
