how much does a cheap muffler go for these days? not one of those stainless steel wonders. i would really want something with a very big "tank" (that's not the resonator i think) to silence my annoyingly loud engine.

is the engine noise only a function of the diameter of the exit pipe (muffler tip)? or does the size of the "tank" also affect it? my engine noise is so horrible it sets off alarms in the parking lot, and the constant bass drone is very tiring on long drives (like on the expressway).
