Acura / Honda NSX High-Flow Catalytic Converters


   Built, designed, and fabricated for performance. B-Line Motorsports is proud to now offer high-flow catalytic converters for `96-`05 NSX’s. Constructed entirely of 304 stainless steel from end to end, and TIG welded, consisting of 2.250” tubing and laser cut flanges. Allowing you to take full advantage of aftermarket headers and / or exhaust systems. Removing and replacing the restrictive OEM units with our direct bolt in high-flow cats giving you increased performance and sound!

   With B-Line’s high-flow cats utilizing a 200 cell fully metallic substrate that flows over 550CFM while also being over 40% better then a typical ceramic core converter, with a spun 304 stainless steel shell that can withstand any abuse you put it through. For added measure we have incorporated a "CEL" Fix (check engine light) ensuring that the ECU is not triggering any fault codes due to the increase in flow in from the high-flow cats.

For off-road use only; not intended for public high-ways.
