im thinking of buying a performance muffler for my truck. i got told that i have to reprogram the computer so it doesnt run to rich or lean. is this true or make much or a differeance?

 

Not true. Don't expect a lot of power from exhaust. You'll make more noise though.

 

yeah thats what i was expecting

 

Your engine management system will easily compensate for a loud muffler.

 

Ok I have to poke fun at you.

muffler computer reprogram I think you only have to do this
IF you change the blinker fluid.
