This was an exact replacement for the original exhaust pipe. It fir up perfectly and performs as expected. The proce was the best I could fine anywhere. I received the pipe sooner than expected. Would highly recommend for others needing this part.
Fit my XJ with a 4.0 with no issues.
However thier photo shows a bunghole for the rear 0-2 sensor. This pipe only comes with the bunghole for the front 0-2 sensor for those deleting thier cat. Longevity is a question but so far it works and fits as it should.
