Sorry. No longer on the car. I had it on aftermarket and oem exhaust. Didn't make much difference in sound but pretty sure it helped when I was supercharged. Cats only have about 5k on them and deletes the third cat on gs430's
It did sound good but it was with tanabe medallion exhaust , headers , and a supercharger. So altogether did sound awesome. Guess I should edit my first post.
