2000 Impala catalytic converter

[Achiyan]

i cant tell if i have two converters or just one....or which is which. there is a shorter 'converter' nearer the engine and a long 'converter' nearer the middle-rear. anyone know what im talkin about? and if so which is which?

you would only have 2 cat cons if you had a full factory dual exhaust. The other long one towards rear of car more than likely a resonator.

 

That is your downpipe going to the cat con

thanks. mine doesnt look like that but similiar. i used that image to look at mine and figure which is which. but yeah. the long one must be resonator. i was just confused cus i've heard of some 2000+ impalas having two cat conv. maybe it was 2004-05?

 

btw....your butt is funky

so now im wondering if its my resonator making the noise....i was wondering which was which cus i am now having a "rumble/growl" noise coming from the area. sorta like how cars sound when they start gettin old. seems its right between my resonator and my cat conv. its prolly my resonator. i've read of those rusting through, but then again, impalas also had cat conv problems. i love my car but

If you hold your boot to end of exhaust your exactly hear sissing sound where it leaks .
