Acura NSX Downpipe and Exhaust System

New product

When you need to unlock the real power from your modern turbocharged supercar, a full 3” performance exhaust is the most effective modification you can start with. Excessive backpressure causes bigger turbo lag and slower spool up.

  • Double-layer heat shielding- is used to protect surrounding parts, wires, and hoses against radiant heat from the downpipes.
    Integrated thermal insulation reduces surface temperatures up to 70%! What makes it an absolute winner, compared to usual thermal wrapping or ceramic coatings. It’s very important not just for safety reasons but also affects engine performance by reducing underhood temperatures. We highly recommend this option, especially for catted downpipes.
