WTB: Stock Exhaust Parts 94-95 7a-fe, Looking for front flex pipe, catalytic converter Options

[senick]

As the topic suggests, I'm looking to pick up some gently used stock exhaust components for my 95 ST. It's getting pretty noisy, but I don't know how much longer I'll keep it stock, so I'm just looking for some cheap replacement parts to hold the exhaust together for a year.

I'm looking specifically for the front flex pipe and cat, but I'll also be open to other components as well if you'd rather sell them as a set.

I'm located in northern Indiana, but can pick up anywhere in Chicagoland, SW Michigan, central Indiana. I'll also consider paying for shipping.

Thanks!

Edit: It seems not all 6gc's have the same exhaust setup, so if possible I'm only looking for parts from 94 or 95 STs.

Give me a few days as I just took off mine OEM from my 1996 ST, no leaks no noise I just wanted to put headers on and downpipe. I am taking it in today to shop to get the new downpipe fixed as it is touching the cross member. Once that is done, I will have this one ready. PM me for details.

BTW, I have the OEM header and downpipe. I dont have the cat.

thanks

What type of downstream O2 sensor is on the exhaust? Is it a screw-in type? I noticed the exhaust setup for 95 and 96 can be slightly different, even if they're both 7a's .

[msk59]

On the 1996 STs, the O2 sensor is screw in type. There is a nut welded on the downpipe up front near the header where the O2 goes (if I remember correctly). I will take some pictures since it is out of the car tonight and send you via email if you can PM me your email.

The header I installed is an eBay (crap) SS header and downpipe.

If it's the screw-in type, then I know the fit is going to be different than what I currently have on, and I don't know if I'd be able to just swap out individual parts, or if I'd have to swap the whole exhaust system over to a '96. I worry about the compatibility since it appears that while the 94 and 95 model years share one exhaust setup, it is in fact different for the 96 and 97 models.

[msk59]

I think it fits. The header I am installing in my car is actually made for Corolla. It had a oval shaped bung on it for O2 sensor. different than mine and I was able to buy that adapter and my O2 screwed right into it. I will send pictures tonight PM me your email.

Look at this site, it just shows the down pipe design but basically the difference was OBD I to OBD II as far as the design change. the 94/95 models used a longer manifold with a cat I believe where as the 96-99 models used a shorter manifold no resonator or cat, just flow through. Short answer, if you switch between the OBD generations you have to switch manifold and downpipe. Hope this helps.

[senick]

That's fantastic information. So when you say no resonator or cat, you mean as part of the manifold? That is, the 95 models have an extra cat attached to the manifold before the downpipe?

Therefore, if I use an OBDII manifold and downpipe from a 96+, it will fit perfectly with the rest of the stock exhaust?

[igpx12]

For the manifold on a 94/95 that's what I mean, basically a collector is built into it. From the cat back its the same part #'s even OE, so yes it will bolt right up. The one critical part to not change is the O2 sensor because if you use one that is 96+ the values to the ECU are different. The 94/95 uses a separate flange the the sensor threads into and is then bolted to the manifold, so all that means is just remove your current O2 from that flange and it will bolt right to the 96+ set up.

[msk59]

I sent you pictures of my setup. My car has no cat in the manifold thus a shorter manifold and longer downpipe. The flange is in the down pipe.

[senick]

Are you sure the O2 sensor will fit both setups? I don't think the OBDI sensor has any threading to fit the OBDII style exhaust.

[igpx12]

Yeah, just use an O2 socket and remove it from the flange

[senick]

Now I get it...I was under the assumption that the sensor was welded onto the flange. If it's just threaded into the flange then looks like it's just a straight conversion from a 95 to 96 exhaust. Thank you very much for the help. Will the sensor just take a regular deep socket, or I assume a ratcheting gear wrench will also take care of it?

[igpx12]

If you don't have an O2 removal socket, you'll want to use a standard wrench, but be prepared to crank on it cause of the heat warping. For my downstream I used two wrenches to create leverage using the open end on the O2 and the other wrenches open end on the closed end of the one on the O2. However you get it, O2 socket is the easiest if you have one, deep socket wont get around the sensor wires.

[senick]

Great advice, thank you. I have a pass-through socket set, I think I'll give that a try. If that fails, I'm sure I'll find a way to remove it.

Also, since I'm reusing old exhaust parts I thought I'd clean with a strong degreaser and then cover them up with some exhaust grade rustoleum. Cheap way to do it, but I really only need the parts to make it through another year at most.
