Exhaust leak to bigger problem?

Okay so I've had a exhaust leak from either a blown gasket or a cracked manifold and for the longest time all it has done is made that annoying ticking sound of escaping exhaust fumes. BUT now my car is sputtering, not bad, but its gotten even more annoying and I would hate to have to pay a mechanic an 80 dollar diagnostic fee if all it is is the exhaust leak. Any ideas what it could be?

The car is sputtering as in making a sputtering noise, or actually hesitating sputtering?

Re: Exhaust leak to bigger problem?

ok, what kinda of vehicle are we talking? the later model v6 mustangs have a terrible problem cracking exhaust manifolds. usually, its the passenger side (i dont know why)
just a theory but its possible if the crack got big enough, the o2 sensor reading would be off by a great deal. outside air being monitored by 02 i mean.

Its an 01 and it is actually hesitating sputtering. Will the o2 sensor automatically correct if i repair the leak.

You're going to have to elaborate on "clear the code"

Re: Exhaust leak to bigger problem?

disconnect the battery, and let it sit for 5-10 mins. That will get rid of the check engine light and then you can see if it comes back on.

Get the car in the air, start it, and find the leak... If it's that noticeable... it won't be hard.

Re: Exhaust leak to bigger problem?

Both of my stock headers cracked on my 2002 V6 when I had them swapped for some MAC shorties. (I had about 102K) on the clock when we did it). Not only is my car now tick free and also have a great sound, but I also gained about 10-20 miles per tank of gas. Didn't do anything else except swap out the headers and boom theres a couple bucks back in pocket every time I fill up. More of a piece of mind mod if you ask me as it didn't really gain any sig HP gains, but Its better set up for any future mods now with a higher quality product.

my problem was indeed NOT the manifold being cracked but the exhaust pipe at the converter itself had broken clean apart. i re-welded the exhaust. a new converter only comes as a set from the dealer and costs 1900!

Why not just swap that out the stock Y-pipe and get a H/X-pipe with some high flows for a fraction of the price?

Re: Exhaust leak to bigger problem?

Oh true, yea I'm not sure I know anyone that would pay for a $1900 stock Y-pipe.

Re: Exhaust leak to bigger problem?

I went over steep incline followed by a steep decline and popped my header right off of the rest of the exhaust piping. My dad called Ford and they wanted the same price!!!!!!!! because I have a busted CAT also due to lowering. And they wanted $2500 to fix the broken header and to put a new CAT on. So i told my parents to forget that and i will go up to the local exhaust shop and fix the header for like $200.

you could get long tube headers, mid-pipe and "cat-back" for ~$1000.... you would be retarded to pay that to replace stock exhaust.

Re: Exhaust leak to bigger problem?

I am not going to get LT headers if i already have scrapping problems considering they drop .5 inch more than stock exhaust. That is suicide for my exhaust and it would be a matter of time before i meet a speed bump to tear it off due to my lowering springs.
