So I got some 87 TPI exhaust manifolds. I'm told it takes a spacer or donut deal to mate it to the y-pipe, I plan to use the magnaflow y-pipe




. My question is I bought a spacer supposedely" for this on ebay and was wondering if anyone could tell me is this the correct piece?

Hmmm...learn something new every day. I thought the extra think donut spacer was only used on the carb L69 manifolds, and not the efi ones. Or are they the same manifold?

L69 and TPI manifolds are the same except for 91-92 Automatic TPI 305 manifolds which are the smaller type like L03 and LG4 from what ive gathered. Ive also heard theres a spacer in between the manifold and y-pipe on these HO or "better" manifolds and that's what I'm trying to get together.

the carb'd exhaust uses an EFE valve there that closes to direct that side's exhaust gases through intake manifold passages to help warm up.

the TPI cars use a spacer-the manifolds and y are the same pieces. that is not the spacer that I have run across, but I can't say that it is not maybe correct for some years, etc.

I'd try it and see, looks maybe to be the right thickness.

Pretty sure it's upside-down in the photos.

That donut was not the correct one. I now have the correct one on the way thanks to beths91camaro. Thanks

I've had some good dealings with beths91camaro ...

There's a few pics of the stock spacers in this post:

Thanks John. Hope its the right one I have.. The first spacer I bought seems to be the smaller diameter for TBI or LG\4 style weenie exhausts.
