I have a 1987 Fiero GT and it has a very bad exhast leak. I cannot seem to find where it is. Should I take it to a muffler shop and see if they can find and fix it? It might be by the manifold im guessing..? How much does this usually cost? Am i better off just replacing the whole exhast system and/or manifold? Thanks i appreciate it!

You can take it to a muffler shop, and they should be able to at least find the problem.


Check the manifold near the firewall. I just had to replace that on my '87 GT.

If the manifold is cracked, it may be expensive to have the muffler shop to replace it.

This is sometimes the cause.

I agree with Mitch. I had my manifold gaskets blow out on me not to long ago, and if it is them, I'd change them both at the same time. If one blows the other is about to.

Yup... could be a broken manifold, broken bolt(s) or bad exhaust gasket.

Pain to change, sometimes. I had to pull the heads as I had bolts break.

Check this out. These are $0.19 gaskets for a VW that fit great and are a lot less than $25 at the part store. For 6 delivered to my door, it cost me a grand total of $3.33

$0.19 EDIT: Rockauto part BECK/ARNLEY - 0396098


$24.99

If you suck some Seafoam into a vacuum port, let it sit then start it back up, the smoke can reveal the leak.
