what does a upgraded muffler do to your car?

Recently bought 96 lancer glxi with a changed header/exhaust manifold. What are the advantages of a upgraded header? What are the differences of a original/stock exhaust manifold. Thanks

Aftermarket exhaust manifolds increase the horsepower and in most cases improve the mileage of your car.

depending if the I/H/E was done according to the specifications that would most benefit your car. Other shops make hula lang bro. But to answer your query. More low end / top end power. Depending on your header 4/1 or 4/2/1. Increase fuel consumption. But to sum it all up use your butt dyno and you can feel it. Try to advance your timing for a couple of degrees and change to 95 octane. Then tell me what happened.

Upgraded car mufflers would possibly make your car more efficient than standard exhaust. Upgraded mufflers make cars "breathe" more freely, thus, giving the car more power--that was initially trapped inside because of the standard exhaust.
