hey all just wondering, my friend has a 00 ex auto and won't swap to manual so he has most of the basic bolt ons but wants some more. now i've had a few other friends w/ auto civics that put headers and a freeflow cat on and ended up w/ a toasted tranny. is this a backpressure problem caused by the headers and cat or is this a myth. and mostlikely caused by another problem? just wondering because he'd really like to get some more goodies. anyone here have a auto w/ headers and a cat w/ no tranny probs?

 

nope, the headers, and cat will not cause this problem. its probably because, with the mods, they drive harder, straining tranny.

 

Yeah they probably just think they are mad street racers after they put that stuff on and drive alot harder. Honda auto trannies aren't meant for race cars.
