Hey,

I am getting really pissed off with this car. I received a ticket due to the excessive noise from my exhaust. It has been broken at the y-pipe for over 9mos now. I get pulled over Oct 25th (month end mind you) and receive a $75 ticket for faulty exhaust. I have 30 days to get it fixed and they will drop it down to $9. So I have been in search for a replacement. I got one from Ian at 944Online. I drove over to his shop yesterday (a 4 hr drive) an picked one up. I installed it today, and made sure everything is tight. I finally fired her up and man she sounds Horrible !!!!. It is not from the ehaust but from the engine itself. Could it be that I messed up the internals while driving her without the exhaust repaired? Could the O2 sensor cause some of the problems?, I had to splice and connect the O2 sensor since the wire broke when the Y-pipe broke. Should I bite the bullet and have the shop check and see if something is wrong ?

Did you replace all your exhaust gaskets when you put on the new pipe?

Joel's_84_944

Yeah,

I got new gaskets and bolts/nuts for the replacement. I tightened them according to specs of the Haynes manual.

how horrible is horrible? It should sound a lot less loud then before with out a broken exhaust. Do you have a microphone and a laptop? or a vid camera that you can load tot he computer? if you do you should get us a sound clip.

Look to see that the gaskets between the headers and motor are in good shape. If one of them is off or messed up, it will sound like a NASCAR.

check for cracks in weld spots.

maybe drivin around w/ the y-pipe broke caused the header to break too........

CPTdooberhead

I agree, it sounds to me like this is your problem

Sounds like a blown out gasket at manifold to engine, or the manifold itself is cracked open. You probably have the steel manifold, and this would be quite common AFAIK. I would try to find a set of cast iron manifolds from an "83, they are much, much more gooder. Re-welding steel manifold will work for a while........maybe. Good luck!

Joel's_84_944

OK,

I will try and check the exhaust manifold to see if they are either loose or cracked. I will order new Gaskets and replace them just in case. I'll keep you guys up to date on the problem.

I remember when my friend with a V-8 Mustang asked me to drag. I told him he would win.He insisted, so I gave in. Next Friday we go to the drag strip, the night before I took off the headers so my exhaust sounded LOUD, lol. He "wasn't in the mood" to race that night....

Joel's_84_944

Well,

I drove the car to work this morning (she's my daily driver) and it sounds like a loud tapping sound from the engine area. When I give it some gas it gets faster and louder. When she's Idle I can still hear the tapping but not so loud. When I get to a comfortable speed and just cruise(60 mph on the highway) leaving the accelerator still (not letting off and not giving it more gas), the noise disappears, but as soon as I need to pass someone and give it gas, the tapping comes back.

I ordered the gasket and will replace it on wednesday, since I have that day off since I have to work on Saturday.

thats definatly manifold at the engine. replace them gaskets and make sure theres no broken studs.

One trick to track down an exhaust leak that usually works. At night when it is very dark out shine a flashlight, not on the exhaust areas but across the areas. The exhaust leak should show up as particles in the beam of light.

Good tip TheMAXX. I would also say it's the gasket. It doesn't sound like a rod knocking, does it?
