Stage 1 exhaust installation questions

[delornut]

I hope to be installing my new, used stage 1 exhaust this next week (all I know is its a SS version). I had a few thoughts and questions...

I need to pass CA emissions here, if I need replacement cats down the line, any thoughts on where to get them?

The cats I've seen on most of the various exhaust kits look like pre-cats used on a number of vehicles. The last several years of the Ford Ranger we built with the 4.0 engine had pre-cats that looked exactly like those. They were installed one on each of the two pipes coming off the manifolds along with another cat installed after the exhaust blended into one pipe.

I would not use POR-15 on exhaust parts. It was not made for such a high temperature application. Eastwood has several products for such a use.

I purchased a used original stage 1 kit. Does anyone have and advice when it comes to installation on this? I don't have any instructions just a bunch of parts, and i hope i have all the parts.

I was in a similar situation 8 years ago when I ordered my Stage I kit from DMCH. There was no parts list to make sure I had received everything so I put together the list you see in the attached Word docs. Sure enough, turns out there were a few things missing and we eventually got everything resolved.

At the time I also found a very good installation tutorial. I think I found it in a Delorean magazine. I was not able to find the softcopy so I scanned in my hardcopy.

I hope it helps.

Henrik, thank you very much for scanning that in. It's super helpful! I areally ppreciate it. I knew there was something like that out there . If only I could find some instructions like that for doing EFI

I know I have to look for high temp paint, about 2000 degree protection. Por 15 does sell a high temp version, as does Eastwood, vht and krylon. I'm also checking to see if any come in a 2 part automotive style that I can use with a spray gun.

Anyone every paint these header with lasting results?

Digging up this thread. Note to anyone looking to install, do NOT torque the studs to 25lbs, it will strip the studs, not sure why that article above is calling for it. But we found that tightening with a small ratchet until snug worked perfectly fine.

Also, on our installation, the muffler is not snug against the bushing on the passenger side, and on the driver's side the tailpipe is touching the cat. Do we need to push the piping farther into the muffler to correct that?

Typical torque value for 8.8 gr M7 x 1.0 is 11 ft lbs. (zinc plated steel) Many other factors can influence torque values though.

I bought DPI's SPEC I exhaust set-up this week. I'm super stolked to get this on the car in the spring. Reading through some previous posts, taking the old system out should be 'fun'.

Can the cross-over pipe be removed without taking the pass drive axle off? I'd rather not mess with that if possible.

No.

No.

Thanks Dave - actually maybe not :-)

Its not a hard removal. I tried to avoid taking them off, but its only a few bolts. Gives you a good chance to really inspect it too. Turns out all 4 boots were torn, so I rebuilt while they were down.
