Will the Y-Pipe on an '85 without cats fit on an "89 to replace the pre-cat Y-pipe?

Thanks.

If the cat is bolt front it won't fit as the later cats are slip front. Otherwise it may bolt up.

the cat is different, if you replace it, you could get it to bolt up correctly

I have not tried this, but almost did.

85 pipe is supposed to be a little longer to the flange. Diameter is supposed to be the same as required to clamp to the 89 cat. So if all of this is true, you could cut the flange off the 85 and a little of the pipe and clamp it to the cat.

Never tried, but a guy on this forum measured it and it seemed as though it would work. Maybe somebody has done it to see.

Why not buy an after market pipe. They can be had in SS and in mandrel bent 2 1/2" tube. The flow would be better than a stock later model pipe.
