Exhaust Problem

When I left the house this morning everything was fine. But when i arrived at my destination my car was super loud. I jumped out to look at the engine while reving it. basically it sounds like i'm running straight headers and i can smell exhaust fumes in the engine bay. I'm guessing header or midpipe damage. what do yall think?

(now when i drive down the street everyone will think that im one of those losers who runs straight headers on a sixer.)

Re: Exhaust Problem

Hmm...could be your manifolds going bad. If it smelled like rotten eggs I'd say it's a plugged or damaged cat. Maybe someone else will chime in who's had the same issue.

Re: Exhaust Problem

you can check for an exhaust leak, some v6's are known to have issues with the AC dripping down on the header and causing a crack

That's true, that would cause a much stronger exhaust smell, not a foul smell, but a much stronger presence in fumes.

Would this dripping be on the driver or passanger side header? I get the feeling that the leak is on the passanger side, but that's just a feeling.

Re: Exhaust Problem

It would be on the passenger side and it is a very well known problem with the V6's. Like spec said, the condensation from the condenser will drip onto the stock manifold and it will crack it.

Re: Exhaust Problem

Well, it was about 34 this morning and I had my heater on. I left the house at 7am and noticed the problem when I got to my destination 15 min later. Sadly I don't know when it started cuz I had my music up loud. What I'm trying to ask is: could the dripping still be the cause under the cold weather, using the heater, and only running the car for 15min conditions?

Long tubes means shorty midpipe which means more $$$
out of curiosity, how much of an advantage is there in long tubes over shorty headers?

The leak/craking is not something that is caused by a one day usage. It is an accumulative issue. It can take a couple years to develop depending on how much you use your AC/heat.

There is a good bit of difference between the two. Shorties are relatively low benefit. The only true gain you get is from the smoother piping vs the rough cast stock manifolds.

Long tubes on the other hand help with scavenging and increase the efficiency of the motor generating greater power gains.

However, you are right...there is a good cost differential between the 2 because you do have to buy a new mid pipe.

Re: Exhaust Problem

I had a similar problem with my old Ford Escort. It was just the exhaust manifold gasket that needed to be replaced. It took me about 4 hours to change it out but it only cost about 5 bucks.

Mine was no Georgia Peach when I bought it either and mine is the same year as yours. Looks like the previous owner of your car were ******bags, though.

Re: Exhaust Problem

After wrecking my truck i got a 01 auto from my wife that her father took care of and got her a new 07 fusion. So some @$$hole in a chevy pickup makes a left turn from the right lane and takes the front end off. Dont ask how but cops say i was at fault "failure to control speed" . So i go looking for another one and got an 00 Manual.

1.Header cracked
2.Rear pass brake stuck
3.Weld on Cat cracked
4.Found out car was in accident (although dealer had carfax that said it wasnt)
First Used car I've ever bought, will I ever buy used again? Hell NO

By the way they call me crash around here. Wrecked 2 motorcycles, Flipped an 04 Ranger, 2 accidents in 01 mustang (one was a deer), had a hit and run in the 00.

Re: Exhaust Problem

Sounds like your car has had a rough life. only other thing that went wrong with mine was the water pump. but that sort of thing just kinda happens.

MGW shifter is amazing. it was worth every penny. now if only my car shifted easy all the time... i dont know if its just my car, or mustangs in general, but sometimes the car shifts into gear easily, other times i have to push some. I know its not the MGW shifter because it did the same thing at stock.

Re: Exhaust Problem

Did you use Synthetic ATF in the tranny? I've heard of it causing problems on frictional surfaces.
