Frequently Asked Questions
Do I need new gaskets or clamps when I install this?
Check your vehicle's service manual for torque specs and OEM gasket recommendations. Most installs use OEM gaskets between the system and catalytic converter — plan to replace those if they're worn.
Will this fit with my factory catalytic converter?
Yes. Catback systems bolt directly to the catalytic converter outlet. The connection point is designed to match your vehicle's stock converter flange.
Can I install this myself with basic hand tools?
Bolt-on installation is straightforward — you'll need jack stands, wrenches, and support equipment. Refer to a vehicle-specific service manual for routing, clearance, and torque procedures.
