I feel like I got ripped off a bit, but I also didn't want to use more gas driving around to other scrap yards to price-shop. You can't just call around to get values of this stuff. they have to inspect the cats in person. Which means you need to cut the pipes off the catalytic converter section before you take them in so that they can actually visually inspect the catalyst material. A sawzall and an angle grinder got the job done for me.

Speaking of using gas, the best part of the trip was that I traveled 25 miles with less than a gallon of fuel. I reset my dashboard mpg reading before I left my house. When I parked at the scrap yard, it was at 28.0 mpg! It was some unusually gentle driving though, because I had the pipes in the back and didn't want them sliding around.
I'm surprised you didn't get more for the catalytic converters. Beats me! I think I'll keep mine for a while based on your experience. I know you're not supposed to sell them but if a buddy of mine needs one for some reason, I'd rather have mine to give away vice the price of new.

I'm not sure I'm seeing the same MPG increase. If anything I'm about the same so far on the highway. I'll have to do better in calculating the actual MPG but I'm on 37s and 4.88 gears. This would be ridiculously rocket fast if I had the stock rubicon tires or smaller. I just burped the coolant system and getting ready to go fill-er-up with some 93!
