will i loose power on my car if i cut off the muffler?

No, infact it increases power (although in small amounts)

But, it's loud. It's illegal. Complications may arise. You can't hide something that loud from the cops. It pollutes. Your car won't meet emmissions standards. Your car will fail inspection. You may be fined.

Go ahead, cut it off.

Depends what type of car you have. Some old beater without all of the electronics you can cut the muffler off without a problem (or simply not replace it when it falls off on its own.

The newer stuff you with all the sensors, it will probably screw it up and it may not even start.

The better question is why cut the muffler off at all. Its going to be a heck of a lot louder then you think it will be- and not a good loud.

Prepare for tickets from the cops if you but it off.

You shouldnt lose power at all.

A muffler has nothing to do with sensors, all a muffler does is 'muffle' or lower the sound. Their are sensor on the exhaust system, but only near the catalytic converter. cutting that off will throw codes and poor performance.

However removing the muffler reduces the back pressure and exhaust velocity. Remove some back pressure, the engine breathes better freeing up some power. BUT, remove to much backpressure and velocity you lose power. Backpressure creates velocity, the velocity hepls pull the burnt gases out of the combustion chamber. take away that velocity and some gases stay in the chamber, taking up space that the clean air/fuel mixture should be...

Your performance gained't replace, you'll in basic terms develop into " ear and eye sweet " for the community police and also you'll then be making use of a vehicle that appears like the muffler changed into bumped off. a minimum of evaluate replacing it with a good setting up performance muffler instead. sturdy success

WHY WOULD YOU EVEN CONSIDER THIS?
