View Full Version : 94 Y-Pipe with cats DO NOT Fit an 89

Well I found out the hard way. I'm having problems passing emissions so rather than buy a pair of $160 cats I thought I would remove a Y-Pipe from one of my 94 donor cars. Well it doesn't fit the passenger side exhaust manifold. Oh well Time to dump some money on some cats!

Why not just use the passenger side exhaust manifold from a 94?

Broken Exhuast man bolts,
EGR Tube may be different, (some later super coupes didn't have egr!)
Very hard work. R&R TWO manifolds.
All this to put on a restrictive exhaust that could blow my headgaskets.
I have the cats, so I will just weld them in to the old pipe.
