Product Description:

The NSX’s factory units comprise two major components; A 600 cell primary cat with an unnecessary, restrictive secondary catalyst. QuickSilver's race catalysts comprise an easy-breathing 200 CPSI primaries with secondary cat deletes. The secondary cats are located post-sensor and are replaced with no impact on emissions, and no CEL’s.

The result is a crisp, 6-cylinder symphony which darts up the rev range with impressive pace – a vast improvement from stock.
