Reconnecting Exhaust Pipe (Page 1/2)
Cunnive OCT 04, 12:30 AM
Hello fellow fiero friends!

This is my first post on these forums for which I am extremely thankful for and wanted to reach out for some help.

I am not a mechanic and this is my first project car and I was hoping someone can provide some help. I apologize in advance if I am not explaining things correctly or I am misusing certain words.

That being said, what I did was disconnect my exhaust pipe and allow me to explain where exactly. Starting from the exhaust tips, the 2 tips merge into a single pipe which then meets the catalytic converter and connects to what I believe to be the crossover pipe? The exhaust appears bolted to another pipe through a bracket with 2 bolts and 2 springs. This is where I disconnected the pipe.

Unfortunately it did not disconnect cleanly, mainly because the metal bracket that the 2 bolts were holding onto was completely rusted and ended up breaking. I was able to disconnect the pipe and remove the pipe flange gasket and this is where I am left with.

Exhaust Pipe

What I wanted to know was, what parts do I need to reconnect these 2 pipes (besides the flange).

Thanks for all the help!

You would need the exhaust crossover or 'Y' pipe. This pipe bolts to the two exhaust manifolds and has the EGR valve mounted on it. The pipes are specific to years. 85-87 is of one design and the 88 is of a different design. They are interchangeable to the engine but won't connect to the lower portion of the other years without mods.

Is there by any chance a less expensive option? The pipe looks like I just need to clean off the rusty crap and get a new bracket to reconnect the pipes.

The only way can think of to replace the flange would be to remove the Y pipe, have the flare shown in your picture cut off, a new flange slipped onto the pipe, then the flare welded back in place. It may cause it to later break at the weld, but a sleeve could be slipped over the cut and welded on each end. This would strengthen the pipe where the cut was made.

I had a similar problem in that the holes in my crossover pipe were rusted but the flange was good.
Since the crossover was in good shape I just got a split flange.
I`m not sure the one below is the right size but they make other sizes.
The flange hinges open to slip around the exhaust pipe and when you get the right size the holes line up pretty good.

If its possible drive it to an exhaust shop. Should be an easy fix with some extra metal and welding skills.

@TXGOOD

Can I still use this if the exhaust pipe is 2"?

When you bring up that link it shows on that page a 1-3/4" to 2" one also.

Note:
You need to replace spring bolts w/ same parts.
Spring bolts and the "Doughnut" seal often go in the joint Allow movement to protect the pipes.
Many fools uses any bolt w/o springs and exhaust breaks anywhere that's weak.

Can usually get them in most local places under Dorman Help!

Hey, I resemble that remark.
I thought about that when I replaced mine with solid bolts but when I looked at how the exhaust is designed and being that everything
seems to be attached to the cradle I figured how much can it move.
But, it may come back to haunt me.
By then I won`t mind spending money on the new crossover pipe if it breaks.
