How bad is traffic in Houston ? If you're stuck in traffic often, I would not cut the muffler off. One of the primary functions of a Muffler is to pass exhaust fumes out the back of the car. Without a muffler, those fumes will come up into the car if you're sitting still for awhile.
Do what you want, just my $.02
