i just want to spread some knowledge here about exhaust design and fabricating...
-the higher flow the muffler you put on your car is the higher rpm your power and torque will be at... other things that have this effect are
-bigger piping
-headers
-higher flow cats and/or test pipes
-on daily driven cars these parts will reduce the amount of power at the lower rpms of the rev range, since you have to rev higher to get the same amount of power your gas mileage will go down, also when there is less backpressure to slow down exhaust gasses they will not be able to hold seals in the engine properly, and the engine will slowly burn through such things as piston rings and head gaskets. remember that honda designed these cars engines with that specific exhaust holding a certain amount of air pressure into the cylinder of the engine on the exhaust stroke... also the o2 sensor not only determines how much to richen or lean the engine but also the amount of flow in the exhaust it can only properly adjust to about 10% more or less than the normal exhaust flow any more than that and you may have problems with running rich. a good performance muffler for a 4 cylinder car will need to still have some backpressure otherwise you may need to get your computer reflashed and that will only take care of the fuel mixture you will still have to take care of your seals... also remember that in order to run a good performance exhaust you also need to run a higher flow intake to keep the air coming in the engine as fast as it is going out of it... a good ides if you like those canister style exhausts but don't want to risk your engine is to put a muffler upstream of the rear axle and continue the piping to the canister at the bumper... but anyway i know a lot about exhaust if you want to know how to get the perfect balance for your car i can suggest some mufflers
