Exhaust

[hav]

I have a 99 Camry V6 (XLE). Few days back there was a sudden noise in the exhaust. I thought it might be a leak and went to a local shop to get it fixed. It seems that I have to change the y pipe and the catalytic converter. They say I have a rough idle (which I do) because of that. The previous owner might have bumped it somewhere and it's constricted, which allows lesser air flow, heating the engine more. Can anyone suggest what I should do and what is the amount I have to shell out for the repairs? Can I drive the car for a few thousand miles without hurting the car?
Thanks

unless its severly damaged (constricted), it should not cause ur idle to be rough, or cause the engine to overheat. if it is then id get it fixed pretty soon, but i would also get a sencond opinion from another shop if u can or look fo the damage urself, it would be pretty easy to see if its that bad. how many miles on the car? the idle may be an unrelated problem.

I have 112 K on the Engine

u may wanna try cleaning out the throttle body and see if that helps teh idle at all, that might be the cause. and id really advise chicking the exhaust for problems urself. like i said its fairly easy to see and unless u found an honest mechanic, ull prolly save ur self a bundle.

How many miles should i expect on a gallon on a 1999 Camry V6 XLE. It has 112 K on it.

21mpg seems about right if it's no more then 50/50 driving, since on my '94 V6 I got like 19-20mpg mostly city, and around 22mpg 50/50.

damn thats all u got, i get around 23-25 city. then again, im a pretty doscile driver...when i wanna be .
