Harrison Signature - High Flow Catalytic Converters - Aston Martin V8 Vantage 2005 +


As exotic and refined as the Aston Martin Vantage V8 is, there's always a hunger for more performance out of your luxury sports coupe. Our high-flow catalytic converters feature free-flowing, 200-cell cats helping enhance performance and give your Vantage a deeper, throatier tone without sacrificing any reliability.  Factory catalytic converters are designed to restrict exhaust flow, so remove that bottle neck with our ready to bolt-on HFCs.


The result is extra performance, faster acceleration, and better throttle response, while your ears enjoy a deeper tone to your vehicle without the obnoxious rumble a complete exhaust system can give.  Maintain the luxury Aston Martin intended with your Vantage, but give it the performance you demand when you get behind the wheel.



US-made RathGibson 304 stainless steel

water cut 3/8th-inch thick stainless steel flanges

special tooling made for a factory OEM fit

    Great product. They fit like oem parts. They haven't thrown a cel code. The car is quite a bit louder, but I have Quick Silver sport exhaust. When I install an x pipe that should quite it down some. You can definitely fell the difference in the power.
