Worked to replace the muffler someone had previously removed. Surprisingly not very loud. Not sure how well the long term will be as this was used on a resale vehicle that was missing the muffler for unknown reasons. Fit and finish were decent given the price point. I did have to make a bracket for the mount point at the back of a transmission but the original mounting bracket was missing so that is probably the reason why I had to fabricate one.
