Frequently Asked Questions
Will this bolt directly to my exhaust system without modification?
Yes. This assembly mounts at factory points and connects to your existing exhaust piping. No cutting, welding, or adapter fabrication required.
Do I need gaskets or fasteners beyond what comes in the box?
The assembly ships with the converter only. You'll need exhaust gaskets and bolts to secure it to your manifold flange and downpipe — check your vehicle's service manual for the correct part numbers and torque specs.
Can I install this myself, or do I need a shop?
Installation requires lifting the vehicle, removing the old assembly, and bolting on the new one. Basic hand tools and a jack work, but working under a hot engine requires caution — shop installation is common for this job.
