my friend says that i can put a straight pipe on basically jus takin the cat off. i thought that was bad for rotaries...

 

Good for rotaries, bad for da earf.

 

Been covered a million times. :-)

Removing the catalytic converter has not adverse effect on the engine, only the emissions that it puts out.

The question that also has been asked a million times is. Will I have problems if I remove the air pump.

The answer is yes if you still have the catalytic converters on and no if you do not have them.

Class dismissed.

 

thanks
