suitcase exhaust replacement

hey,
I was researchin on the net and i was thinkin about cuttin out the suitcase muffler on my exhaust. I was wounderin, if I did that, if I would have to get a tune up or hook it up to a computer and get it recalibrated??? I was also wonderin if it would increase or decrease my fule consumption. right now im gettin about 19-20 mpg. any advice would really help!!!!
thanks

By suitcase muffler your meaning the first muffler? If so no. Actually all exhaust work won't cause reprogramming or anything like that at all. It might help your gas mileage a bit. It will also help with horsepower too.

thanks for the help. now i can get my exhaust cut up and make it not sound like a remote control car anymore
