Ive been contemplating on getting some mufflers installed, most likely magnaflows 11225, for those of you who have an exhaust/muffler on your car, have you noticed any kind of increase in gas mileage, or has it just stayed the same? Im mainly wanting to do this to save gas!!! any help is appreciated!

honestly, it made my mpg go down alittle just because i was gassing the car more to hear the exhaust :P I can say without a doubt my emissions got cleaner!

Id say it probably wont make that much of a difference, but the 1uz is a beast worth hearing! and your ls will definitively feel peppier. I say do it anyway. :biggthumpup:
