Undercoating - worth the money?

Wow 1-2 MPG, when I put mine on it took me a week to get my foot out of it and then I reallized about . 5 to 1 MPG increase.

I reset mileage thingy and test drove about 30 miles EASY on purpose. It was obvious at the mileage increase. Then my FOOT went in it. a few months later I did the AFE Pro Guard 7 filter thing. Really didn't notice any increase with it tho it seems to spool a little faster,sounds better etc. Maybe heavy towing it properly helps when it drinks LOTS of air. :D

I went with a MBRP system. Installed it at the parking lot at Lee's this weekend. It sounds sweet. Just a hint of rumble at idle and not any louder than the stock system, until you put your foot in it, then it roars like a tractor trailer. I think I got about 2mpg out of it. I won't be able to tell until the new wears off, and I quit going under bridges and next to jersey walls. I got the dual setup. Look at the different tips available, the double wall type seem to be made better. Oh, you can also hear more turbo through the exhaust. I also noticed my EGTs are about 100* cooler. Running up a hill at 75mph with 10psi boost in 6th, I am showing a cool 600-625*.
