Default Adding a catback exhaust loses power ?

I heard from anoher forum that adding an exhaust system may actually steal power from your car. is this true ? I was thinking of buying a meganracing drift-spec catback ex. for my 99 civic sedan but i don't want to lose power ! Also, is Megan a good exhaust co. ? I was looking for a reputable catback exhaust around $300. thanks guys.

You loose some torque with an exhaust, but most mods that increase HP sacrifice some torque.

On a naturally aspirated engine, 2.5" or greater MAY actually loose some power because the exhaust velocities are so low.

2.25 -2.5 are fine for a honda engine that is na. if you have plans of turboing your car larger than 2.5 is pretty much a must to gain maximum power.

thanks guys. I was looking around and saw that they offer an axleback and a catback. What's the difference ?

It is widely accepted that 2.25" is the most balanced size of pipe for the N/A 4 cylinder.

Axle back starts at the rear axle, and provides .0000000000000001 HP.

Cat back replaces everything from the catalytic converter back. Provides maybe 5hp.

thanks ;D any suggestions on where i can find a good catback w/ 2.25 in piping ? and does the tip count in increasing/decreasing power. i found this one w/ a 4 inch tip. would this be any good for my 99 na civic sedan ?
