I can run my LS6 M6 Z28 with 4:11's, with the stock LS1 tune through an entire tank on the freeway and get right at 29mpg. It is now tuned and I average about 19-22mpg, per tank with everyday driving( I have a heavy foot to). I had 3:73's for a while and the mileage was pretty much the same. You shift a lot at first with the 4:10, like into second before you are across an intersection but it isnt bad at all,it also makes 5th gear feel more like a 1-1 gear instead of an over drive gear. And yeah, you can blow the tires off any time, any place!

i'm not entirely sure. but it seems about an inch. it really isn't all that low, but if i tuck up the exhaust an inch - will that cure my problem? if you look - you can see the pipes are hanging a little lower out the back than they could be

also, going up a wheel size and or tire size would help. Im running 18's with 40 series tires. Do you know what springs you have? They also make 1/2 inch spacers you can put between your strut and A-Arm, it will raise your car 1/2 inch and that might make all the difference.

A Magnaflow is already pretty quiet, one of the quietest. However, if it is old and has a lot of miles on it, the packing may be burn out of it, then it will be way to loud. So, you may just need to replace your current muffler.
