In an effort to offer NSX enthusiasts the utmost in high-performance headers and after-cat systems, Billy Boat Performance Exhaust created its Tri-Flo Performance Exhaust for the Acura NSX. Fabricated by hand, the system is constructed entirely of high-grade T-304 stainless steel, offering great looks and a lifetime of performance. The header and muffler system was tuned on a chassis dyno for the perfect performance and sound enhancement. Catalytic converters are retained and the complete system is a direct replacement for the original equipment. Header and muffler are available together or separately with your choice of 4.5" x 3" oval tips or DTM tips. Call for DTM tip option 1-888-818-8318.
