Hey all,

I went to the local pick'n pull this weekend and was lucky enough to find a fully intact 89 gts. I took off the exhaust muffler and piping up to the catalytic converter. I was wondering if anyone knows if the exhaust manifold will bolt right in place of my GT one. The gts manifold looks a bit beefier and i reckon it would give me a bit more power.

It will bolt on at the engine point, the question is more of the bottom half -- make sure you get both pieces as the 3SGE used a 4-2-1 manifold versus the FE's one-piece log style. Connection to the front pipe, and making sure your catalytic converter(s) are in place is the issue.

The gains would be minimal, but it would technically work.

As Galcobar said though, the cat will be the issue. It's built into the manifold of your 3S-FE. I'd take the whole system. Make sure to get the heat shields too.

Actually, come to think of it, the Cali version of the GT-S should have two cats.

Thanks for the input. I went back to pull it off and someone had banged it around... Lesson learned. I did however, talk to my local muffler guy and he filled me in on what's hot these days. Apparently, "kids these days" are putting on headers and running the exhaust straight through, and just saving the stock setup, with cats, for smog inspections. So for now, I just put the GTS exhaust muffler on my car. Not much difference other than the looks, and my car sounding a bit sportier. Overall, i'm quite happy with it for now.

With the exhaust off and the spare TEMS GE exhaust handy, I decided it was time for a swap
The FE exhaust is probably good as a boat anchor and that's about all, it weighs a ton and the cat is a
brick as far as performance goes, the firing order on these headers is also wrong.

The GE exhaust bolts right up, only difference was the rear flange size (to the GE cat)

I'm happy to report that performance is way better and the car now has a growl it never had before.
A better option would be to find a gen2 exhaust or some aftermarket headers,

this is a very cheap and worthwile conversion
nb. If you decide to use the GE headers, 1st check the header for cracks between the cylinders

Awesome! Thanks for the pics. I will taking a drive to 4 different pick'n pulls tomorrow to see if I can't find another one.

Get the whole thing including the bracket and the clamp.
The O2 sensor wire will need to be made longer
Check the rear flange 1st, they may be different sizes and not match up as some FE exhausts are skinny
GE has the cat under the handbrake, it won't fit the FE pipe unless you add in another flange, I left it out.

No luck today. :(

I must have found 10 Celica GT's today, and only 1 GTS, and it was completely rusted.

I will wait a month or two and try again. hehe.
