Frequently Asked Questions
Do I need new clamps or hangers to install this?
The system uses factory mounting points, so your existing hangers and brackets work. Clamps are not included — you'll want to source new band clamps or U-bolts to secure the joints during final fitment.
Will this bolt directly to my stock manifolds and catalytic converter?
Yes. This system attaches at the factory connection points on your manifold and cat. No adapter pipes or custom work needed.
Should I have this welded, or can I assemble it with clamps?
Either method works. Clamp assembly gives you disassembly flexibility for future maintenance. If you go that route, use stainless steel band clamps rated for exhaust temperature. Welded installation is permanent and cleaner looking.
