Frequently Asked Questions
Will this bolt directly to my stock exhaust manifold and downpipe?
Yes. This assembly uses factory mounting studs—no welding, drilling, or adapter fabrication needed. Line it up with your existing manifold studs and bolt down with the hardware you already have on hand.
Do I need to do anything to the catalytic converter before installation?
Inspect the inside of your exhaust ports and pipes for carbon buildup before bolting on. A clean connection point ensures the best seal. The converter itself ships ready to install—no priming or coating required.
What's your return window if this doesn't fit?
Test-fit before running the engine. If it doesn't align with your manifold studs or hits the transmission tunnel, contact support within 14 days for a return. Keep all packaging and hardware in original condition.
