muffler with & w/o silencer, any effects on the engine? Options

ok i know that it will reduce the noise but will it restrict the airflow or mess with any backpressure? I had one a long time ago and somebody stole it off my car. now im buying a new silencer for it because its too loud sometimes.

I've noticed that when I put my silencer in, it take awhile for the car to adjust to it. It just seems like it doesn't quite have the power. Then, when I take it out, the performance stays the same for awhile, then takes a very slite boost up after bit. It's such a small difference that it's hardly worth mentioning.

Its gonna reduce airflow. But wat the heck, you got an ST its not like it really matters anyway. Just don't put on a 3" turbo exhaust. That thing will suck up gas like crazy and give no HP.
