Increased gas mileage by 10-15%. Sounds good. Slight droning.

driver side cat was not manufactured well. It properly fit into place but the hole for the O2 sensor was machined off center. One of the two bolts for the o2 sensor was also bent. Had to have it professionally reamed and a new bolt put in. Other than that 70 dollar fix, the cats themselves seem to be pretty decent.
