:cry:
I was tired of my aftermarket exhaust so i finally got myself to go out and buy me a stock one. I searched forever and finally found one from way far away, and had to fork over 130 dollars for it. Its in pretty good shape so i went with it (and i couldn't find anyone else selling one). Well then i didnt have the support hanger for it, so i try to find one on here, 1 week later someone says they have one, and they will just send two just because, so great. I get the package and its the rubber part of the hanger, not the metal part like i needed. So i say screw it nobody seems to have this part i will go to the dealer, so i buy a little friggen hanger for 20 bucks.

Several days later here i am ready to install this exhaust and what do you know, it doesn't fit. The back of the resonator is hitting on the sub frame right above where the diff mounts on the bottom. Does anyone have any idea what the hell is wrong with this?! I was told turbo and NA cat backs were the same so im assuming this one should work for me. Here are pics

In the last few you can see where the resonator is hitting

Here is how it is supposed to fit.

On top of all that i live in an apartment complex and im not allowed to work on my car, so if i have it in the air it cant be for more than 20 or 30 minuets or someone is bound to see me or report me

does the muffler in the back stick out also? if so you may need to get a different cat... or just shorten the piping a little bit. i know that with the blitz exhaust, people had issues because of the different cat lengths...

the back muffler is cut off so i dont know, so toyota put different sized cats on different cars and compensated for it by making the whole rear part of the exhaust longer/shorter?

i would see how the back muffler fits first, because if it isnt haning off, the exhaust has been modified... but if it is haning off like a rice mobile, then your cat is the longer version....

im pretty sure the whole exhaust is sticking back too far, sounds like the cat is too long, i cant really afford any more right now so il just put the custom exhaust back on and save this job for a later day...

Thanks for the help

N/A and Turbo show different part numbers in the EPC, but it shouldn't matter as aftermarket stuff bolts up to both just fine...

A related question... what are the dimensions of an oem muffler? Just wondering as I'm about to replace mine and don't want to get one that has fitment issues.

can anyone else confirm what the problem is? Im interested in getting this exhaust mounted up soon and need to know what parts are necessary, it seems i need a shorter cat, does anyone know what years etc this smaller cat came on? Maybe just the turbos?

iirc, it's been a while, but that doesn't look like my stock exhaust did at all...

...any of them. I've had three.

Need a pic of the cat you where trying to mount up to...

From the pic with the hanger, looks like you're a good six inches off...

did i sell you that? i think i did. if thats the one off my car it is the stock toyota exhaust of a 89 turbo from california. that might be the problem now that i think about it. i'm pretty sure that is the only car that has a different length exhaust that a little longer. and yeah its hella clean. it looked stainless to me. and says toyota all over it.

i would cut out the resinator (spelling) and put in a straight 2.5" pipe through there to add some grunt to the sound and fix the problem at the same time. or shorten it under the driveshaft where its straight.

Do NOT cut out the resonator if you value your sanity...

Looking in the EPC, the differences are:
-GE
-GTE
-GE Cali

Digging deeper, the 89+ N/A's had a different mid pipe and cat for Cali as well. Looks like you're just unlucky. You could probably just get a shorter cat and save you the hassle of modifying the exhaust that is in perfect shape...

ack, messy situation. See i have a California 86.5 NA, and this exhaust is a California GTE 89. So is it for sure that the "shorter" cat will fix this, or a guess?

Rennat

why not just get 4'' cut out of the exhaust where its straight, and put a band clamp? then you could suck it in a little more, or poke it out a little if you wanted to.

your honestly making this WAY more complicated than it needs to be...

The exhaust is in pristine shape, its not common that you come along one like this, i want to leave it alone and fix it properly. Plus i cannot stand a crooked muffler, even if it is ever so slight.

Rennat

eh... its an exhaust, and your by the ocean, its gonna look like shit in 6months... especially with the rainy months upon us.

and a crooked muffler? thats why i said cut it where its straight. you could cut off a piece where the flange is a get a new flange welded on so its still "pristine" looking...

and measure your cat, i'll compare it to what i had on my 86.5...

Take it to a muffler shop and have them do something for it. They'll be able to fab something up and make it fit (hopefully) well.

take a bit off the down pipe (or collector if you are na) since you dont want to cut up the exhaust..

Photo and measurement of stock silencer 1989 Turbo car. Approx. 12 inches.

NA and turbo cats are not the same. There is a difference in lengths. I want to say the turbo cat is shorter and fatter. Good luck.

Yep, like I said, just get another cat ;)

You probably need one anyway...

I bought this for my 86.5 which was gte converted. It passed emissions with flying colors!

Im still not feeling confident with buying a whole new cat without any actual measurements to back it up. Does anyone have a stock 86.5 NA exhaust that i could compare the measurements with on my 89 Turbo cat back exhaust? This would be very much appreciated.

The thing that bothers me is that in the EPC all the years have the same cat and the same cat back system, so why am i running into this trouble? I see some parts websites that offer the same direct fit cat for both situations and some that dont.

Ive been waiting for a reply for approximately 100 days now but i think its too far gone for anyone to see it, so im trying to bump it back.

Every cat i cant get measurements for is approximately 11.5 inches long, which mine is also, i cant find any evidence that some cars had a shorter cat.

thats so weird.

it bolted up to my car fine with the stock dp and hks dp with the stock cat that was 11.5 (i know this because i had to get a test pipe a cut it down to about 9" for my nurspec to fit right.)

the only thing i can think of is when they welded it back together did the just weld the two piece or did they use another piece of exhaust pipe for a slip joint that might have extended the length.

and i have a 2.5" testpipe made out of my old cat that is 9" long. you can have it just pay shipping. you can shorten that so you can save the exhaust.

CyFi6

that would be cool but i cant find measurements anywhere of how it should be. Everyone that has the stock exhaust that i ask to measure it they are too lazy. I have no idea how long or short the flange to the resonator should be and i have no idea how long the cat should be, and i have no idea why this catback is longer than others there is only one part number in the tsrm. Theres so many questions that nobody knows the answer to because nobody cares about the stock exhaust

By the way the welds on the exhaust you sent me are all factory theres no other welds on it i can tell its original.

looking at the TSRM, N/A and Turbo have different cats and catbacks...

Where are you seeing this? Im showing the same parts for both.

Exhaust:
17430-42052 GE
17430-42062 GTE

Cat:
18450-42130 GE
18450-42210 GTE (and Cali GE)

CyFi6

OK so i have the same cat then (cali GE), its just the rear section that is longer... How does that work though. Does the cat sit further forward on the turbo cars compared to NA then? I thought the mounting hangers for the cat had to be the same for all models but apparently they arent because the cat is a few inches closer to the front on turbo cars.

This also contradicts common talk among the board that NA and Turbo cat backs are the same.

Poodles
03-23-2009, 11:55 PM
Well, I do know the piping is larger on the Turbo catback...

Other than that, I can't really comment. The front exhaust hanger is different on an N/A than it is on a turbo (or year dependant, I forgot)

When you get this exhaust installed, take a video, I want to hear how a stock exhaust in that shape sounds!

^here is what is sounded like on my old crashed car.
