I bought this to replace my 2006 Scion XB muffler with holes and rust. It was a direct exchange device. Fit and fit great. curves. and the size was just right. I used a Walker 31577 exhaust gasket and Walker 36519 exhaust clamp to connect to the Walker 55467 resonator assembly. This made the exhaust quieter than the old one. Good product. After installing it, I saw that its socket didn't reach the rear of the car. it was a bit short. I bought an exhaust tip from a local store to make up the difference.
