Thread: Exhaust leak, Whats the probable fix?

Well first i am new, Post number 1!a

Anyways i have a 99 grand prix gt and it has an exhaust leak on the rear manifold against the firewall. i am not sure what is leaking and its hard to pinpoint. the exhaust did fall off the hanger about a month ago and made the leak worse. with that said what do you think the problem is?

i went to an exhaust shop and they said it was the manifold and i need a new one, therefore they have to replace the whole exhaust for 1100 plus tax.

well thanks for any help. need to get this fixed i am moving in a month to florida from indiana

thats what im not sure of, where do they normally leak from, or should i look at first. i checked all the bolts they are tight. to me its sounds like its coming from the collecter if thats what its called. looks like it has flex pipe in it. but everything seems to be in order and fine. its hard to pinpoint

come down here to florida and ill put it on for you lol, im from indiana too, get outa that hellhole while you still can!!!

i am trying to get out of here, i just lost my job again. so i am getting out of here while i still got some money in the bank. thinking of moving to clearwater so i can go to school downthere after i get on my feet. if i can only get a job things would be awesome.


as far as the leak goes. its not going to be an easy fix since everything is so tight back there. i think tomarrow i am going to be feeling her up and try to find where she is blowing from. hopefully its not a manifold but if it is i can get one for free. My friends grandma ownes a junkyard..


but at least i have a better idea where to start now and how to go about it..but if anyone has any other ideas glad to hear them

you wouldnt be too far from me then, i live in orlando, have family in tampa.

well then, after i move we will def have to have a meet up, drop me a pm so i have your screen name saved, also u can be the brain i pick for many problems to soon come with this. not sure how the car is going to do but hope she does well. plan is to baby her on the way down.

i found the exhaust leak, its at the collector, its not going to be a fun job, but it cost only 6.99 at autozone! going to need some pb blaster fo sho

its the piece with the flexpipe on it.

HIT A BIG PROBLEM NOW, the flange on the flex pipe came off, like the flex pipe is where my leak was at. where can i get another cheap anywhere online?

you can get a new dp, those factory ones always leak, they are a crappy design.

that is what i need. dont really have the extra money for the downpipe. its 20 bucks more with shipping but my res is all f up. so i get to get me a glass pack to put in its place.

well if i go with the complete dp, then i have to get the o2 plug and its 100 bucks. they also sell just the mesh for like 15 plus ship. i think i am just going to go that route i have to get a glass pack cause the res is completely gutted. it fell off when i cut the dp off.
