I need pics if you got them~~
I hit a rock the other night, didn't see it until the last second when I had a choice between oil pan or exhaust....I went for the exhaust, spun the wheel to the left and hit what I think is the catalytic converter....but I also think I'm very wrong...
So here it is, do any of you guys have pics of a stock exhausut I could see ( I don't have a camera) and you can point out what is what down there and I can show you what I cracked........than I need help figureing out how much I'm looking to pay. Thanks again guy's! |

I'll go out and take some pictures now, and then add them to this when I'm done.
Y-pipe and cat, respectively.. Sorry they are so crappy...my driveway is wet, and it's freezing ass rainy outside. I did my best. haha |
Awsome man, thanks much.
|
ok....it's the second pic.....the big one. But mine is alot bigger than yours.
so what is it and how much to replace it at a shop? |
Catalytic converter, and you don't need to have a shop do it. I haven't *actually* looked on THIS car, but every other car I've been under (Ever) has been four bolts and it comes right out. Might be a bit stubborn though...20 years of grime and rust...
You can get cheap cats on ebay...those 'high flow' ones (no name brand, big brand copies) for around $80 I think. Do you have to pass emissions where you are...? Being in California, I'd think you would...20 years might be exempt though :) |
dude, the stock exhausts SUCK nowadays (up here atleast), they are all so old and crusty. you're better off starting over and getting whole new exhaust or atleast a new catback. i've personally seen 3 stock exhausts just break in half randomly, i'd never consider one to be worth fixing.
|
Get Pace Setter!!! :rlaugh:
|
I have to pass emisions.......I do need a new cat though if that's what it is.....it's the big muffler looking thing closest to my exhaust manifold. Is it a cat than?

The best thing to do is to get the racing beat downpipe/presliencer combo for around 300 or the header and presilencer for 425-ish. You could also get the rb header or downpipe and a bonez cat made to fit up to them (you find the cat at the above link.) You can find the RB stuff cheaper in the f/s section a lot of times. |
Gah, just saw your most recent post. Since you need a cat, the cheapest way is to get the bonez replacement cat for 250. Thats the cheapest one I know of that will actually stand up to rotary exhaust temps. For comparison, the stock cat is 1300+ from mazdatrix, and their aftermarket replacement is 450. Since you live in cali and have a visual inspection I doubt you could pass off a header. You might get away with the rb downpipe since you cant tell a difference unless you jack up the car, but I dunno how they do it there.
|
Ditto. Get a new cat. Cats have a limited lifespan. Unless you're selling your car soon, I wouldn't bother with a used cat any more than I'd bother with a half-used oil filter.
Here's a simple breakdown of your exhaust. In order, from the engine: exhaust manifold (pipe) pre-catalytic converter (pipe) main catalytic converter (cracked) Y-pipe mufflers. There is also heat shield surrounding various parts (unless someone removed it). I forget which. That's just thin pieces of sheet metal to keep people/things away from the hot exhaust. If that gets cracked, it doesn't matter at all. |
Just as an example, I used RTV black (700+ degree) gasket maker to help seal my exhuast from the leak around the flange of the midpipe while I was waiting for the rb downpipe to come in. When I went back under it a week later to install the dp, not only was the brand new gasket vaporized, but so was the RTV.

no....in reverse....muffler, y pipe, small cat looking thing, pipe, big cat looking thing, pipe, ex. manifold I cracked the big cat one thing
|
Actually since your car is an 86, it should have two precats, so its manifold - precat1 - precat2 - main cat - y-pipe, etc. The one that the guy posted is the largest cat on these cars. It sounds like you don't have a stock exhaust system to be. First of all, there are 3 "cats" on an 86, and the largest is the main cat (the one closest to the y-pipe). I'll try to dig up a pic of the stock exhaust laying out for reference.
|
thnx man....I'm going to try and find a way to take pics

Ok, the only "pic" I could find was in the haynes manual and my scanner is acting up so I had to take a picture with my digital camera. Anyway, that is the stock setup for your car. Which one is cracked?
|
ok, so the main converter is what I cracked......but than it goes to a smaller one and into the y-pipe. There's no precats before the main one....but it passed 5 months ago and now I just bought it and I have to pass it again....
|
Weird. I guess get the bonez replacement cat. I'm not quite sure how it fits up with the split air pipe, though. I didn't see a fitting for it in the picture. Maybe you could call them up and ask about that.
|
the crap part is that I just need to pass....than I want to hollow it out. would anyone recomend that?
|
ahhh , can't overlook the pan! you can always weld a pipe lol
|
overlook the pan?...you mean the heat shield?.....
|
And for the sake of not starting another thread.......would it be worth my time to do a five lug conversion?
|
If you've got the time and access to parts for cheap, then go for it. The main benefit I can think of is the better brakes and ability to run many more aftermarket wheels.
|
I do have access....two pick n pulls with like 13 fc's
