No pictures (sorry guys). I went and threw some pizza pans on my Blazer and for the first day or so I was pretty pleased. Then they warped, dented, and looked terrible on my car. Yes, I know, this is ecomodder.com and we don't care about looks... but holy crap these look so terrible on my vehicle. Not to mention, they basically become a giant amplifier for the engine but only for the people inside the vehicle. They made the ride super loud. I will say that I could actually feel a difference while coasting. It just felt smoother.
As far as MPG gains go- I averaged about .5 MPG gain. Got significantly LESS mileage on the highway (don't know how). Anyways, I took them off. I value not shouting at my family and looking like a crackhead more than an extra .5 MPGs.
Now, if anyone knows how to combat this noise problem, PLEASE TELL ME!!!! I'll keep the pans around for a bit though. Might even make some pizza
edit: actually I will post pics tomorrow.
