Before You Buy: Make Sure It Fits
Incorrect fit is the #1 reason for returns—but it's easy to avoid. Please take a few minutes to double-check your vehicle’s exhaust pipe diameter before purchasing.
What to Measure
To ensure the CatClamp® fits your vehicle:
- Measure the outer diameter of your exhaust pipe before and after the catalytic converter.
- These are called the inlet and outlet—and they may not be the same size.
Watch: How to Measure Exhaust Pipe Diameter
- Measure the outer diameter at both yellow-marked points.
- Do NOT rely on the size of the visible tailpipe. It can be misleading.
