yeah yeah yeah. like 3 years later for no apparent reason but to piss me off when i need to drop my tranny.

He welded it off the car and we reinstalled from underneath. I have the advantage of my turbo-> downpipe flange NOT being attached to the actual downpipe, therefor I'm able to worm that bastard back in there. I don't think that would be possible with a solid flange.

I ran mine with just the elbow coming from the turbo once the bolt snapped. I must say it was pretty cool hearing the turbo spool, but it sounded like a farm tractor or a small biplane coming in for a landing.:bowrofl:

Trying to put that bolt in was extremely annoying.

Solution that we came up with was to use a spring from a drum brake that we had lying around. Its been on the car for a while now, and no leaks.

Thats clever...

Well i tighten the hell out of it last night, as it warmed up on my way to work this mourning, ppprrrrrrr ppprrrrr pprrrrr > bbbrrrrraaaaaappppppp... rattle.... bbbrrraaaappp... rattle....

Got it welded as much as they could it still leaks a tiny bit on top but i have some magic potion that i will spread all over it once it cools down and hope it seals the damn thing. I'll also toss the clamp on there if it fits between the pipe and the cradle.

where is the air vent for the heater and the ac and so forth? when i'm at a stop light it smells like exhaust in the cab.. i honestly feel dizzy right now.

do you have your gasket between the firewall and hood?

but it shouldn't smell, fix your leaks.

yup that gasket is there, i looked around and could not smell exhaust in the engine bay. Its leaking at the crappy slip joint.

It shouldn't leak, like i said I never used any securing device there. Teh design on the joint should prevent leaks. since top portion fits into the bottom section with about a 4" overlap, it's going to be damn hard for the exhaust to leak out. Plus once it gets warm it should expand and get mad tight dawg.

your best be is a slip-joint band clamp and permatex muffler wrap as a sealant beneath it to really solve the issue.

4" wtf? mine barely has an inch, maybe an inch and a half. I ripped the bolt when i tried to tighten it more.


When i talked to Stephanie she did say they changed the design so now they are using a 4" bolt instead of the 6" bolt i'm using.

The problem i have with mine is my slip joint keeps slipping down. So far it hasnt come off but would make a big problem if it did. Either im going to weld it solid (then i have to take off the manifold every time i want to remove the exhaust) or vband. To me, a weld tack would eventually give way.

If your gonna tack it, just weld it. No leaks garanteed (unless you welded without gas [not flux core])

mine is not tacked, mine is welded however its not welded all around since they couldnt get to it from the top. You think i can take it off from the bottom of the car or do i have to pull the turbo to remove it?

You may be able too. Try it. You may be able to get the joint low enough to where you can get a full weld around it.

i'd do that but i gotta get it to the shop so they can weld it :(

Can't blame us for that one sorry. Not Corky's design idea. Better get back with someone else on that.....

BTW - that is the only downpipe I have seen break like that. Chances are you have something pulling on it.
Stephanie

My begi downpipe didnt hve enough clearance for me to thread the nut on the bolt more than about a few threads, its still hanging on there but it not tight, Im going to put a spring on it pretty soon

I am sorry I confused you. We use the 6" now. We used to use a 4" bolt, but it is not long enough.

It sounds like the previous owner chopped off part of the downpipe. That explains most of your problems. There is a minimum of 2" on a slip joint. Usually it much longer though.
Stephanie

I guess mine's closer to 2", but yeah, that's how mine was installed. i didnt bother with the bolt.
