| While the PowerFlow Stack kits are designed to work on existing 4" exhaust, you can use the adapters and clamps shown here to covert them to work with 3" or 3.5" exhaust. Also available are stack shields for the 5" and 6" straight, curved, mitre and aussie cut stacks. If you have 5" existing exhaust, give our trained sales staff a call and they can help you with the right kit for your application. |
