Any of you guy's or gal's out there using Doug's headers, have pic's of how they fit, and also do you like them?
Thanks Jeff

318, auto,mini starter,and manual steering and they fit pretty nice.I just put them on my Cuda. There was a couple of times that I had to stop and rethink what I was doing but they fit with no dinging or adjusting. I also got them with no scratches to either the headers or the car. As far as the height goes I would say it's a little better but nothing exceptional. I took off my cheap Flowtechs and put the Dougs on in their place. The flange height was identical. While it's true that Dougs go above the steering linkage they drop down to the same height as the cheaper headers.
I have them in my Duster with a 340. 833 4-speed with mechanical linkage, flaming river manual steering box, mini-starter, milodon road race pan, and stock V8 spool mounts with polyurethane inserts. I had to modify the z-bar (same as the TTI modification), and both sides needed some dimples to fully clear the 1.12" torsion bars I have. I also trimmed the corners on my 4 speed bellhousing, which is also mentioned in the install instructions if I remember right. I had to trim that back even more for the TTI shorties.
What exact mod do you need to do to the Z bar, first i heard of this??

That's about it but a 340. As far as the starter goes I was reading that the starter and the headers needed to be put in at the same time. This isn't true, there's plenty of room to put the starter in afterwards.

All my buddies have TTI, just curious about these, I can get them coated for around $150 locally, so maybe by them bare.
Cool, forgot about buying them locally, thanks for the info !!

That must have been some set of Flowtechs, because I've never seen a set of headers that captured the steering link that wasn't a crap load lower. Even if that was true and the flanges were at the same height, with that style you have a foot and a half of exhaust pipe that is as low as the flange, which is worse than just having the flange at that height.
The JetHot coating is a joke.
Installed the headers late in the year, and just 1 very mild winter with some occassional roadsalt has completely stripped the coated from the lower 1/3 of the headers.
Looks like bare rusted metal now.
Low is low. My point is to dispel any notion that you're going to get any more clearance with the Doug"s. While you may flatten out that tube it's been proven that you're not going to suffer any noticeable loss. However, whatever you're going to clip with the flange on a Flowtech, you're going to clip with a Doug's just the same.
If your car is lowered and you have low profile tires, you might want to rethink the cheaper headers.
That’s not true at all. I mean sure, if you’re going across a uniform height speedbump that’s wider than your car that might be true, and even then it makes a difference how close the low spot is to the suspension. The worst spot for clearance is halfway between the wheels if you’re taking speed bumps. But realistically, the ground you travel over is never flat, and the more stuff you have at that lower height the more likely you are to bash it on something. Especially if that thing isn’t parallel with the body of the car. You’re a heck of a lot more likely to snag that length of pipe than the point of a collector.
Low profile tires don’t have anything to do with it. My low profile tires are still taller than anything you could get stock. Overall tire height is what you have to pay attention to.
I believe they are available in 3 versions.
I got the JetHot coated ones, thinking they might last a while...
But it became obvious quickly the coated will not survive some roadsalt.
Here's a fairly recent pic of the underside of my, at the time 10 months old Doug's Headers (but I think any coated header, even TTI's would have looked like this perhaps);

It does in the context I was speaking of, because I was not talking about huge non stock size wheels.
Man the ceramic coating on my Doug's has held up great, with the one exception of where my remote oil filter hoses were leaking oil on the header. It burned off a bit there there. The reducers don't look great (they weren't coated though), but the headers are still nice even under the car. They've been on the car for almost 4 years now...

Just tiny stock ones. Gotcha. Well "low profile" usually means an aspect ratio less than 50, and either way that still doesn't mean much of anything by itself unless you know the width of the tire and the diameter of the rim. Probably not a whole lotta folks running "low profile" tires on 14" rims though. Rocking those sub-23" tall tires! Heck you can't even get tires for 14" rims with an aspect ratio lower than 50, 225/50/14 were the lowest profile I could find. Now you can get some 225/45/13's though, those are low profile.
And a whopping 20.8" tall too.
I am well aware of tire sizes, being in the business for a long time. Not everybody likes short sidewalls. Every time this comes up, you find it necessary to lambaste stock height tires and stock ride heights as if they are the plague. People have different opinions and tastes. Not all the same as you.
We have a moderator and a couple of other members here who run the Summit style headers on their cars sitting at stock ride heights with stock height tires with zero scraping issues.
How do you think it makes people feel when someone like you keeps running down those type cars.....and you are doing that. Do you think they will be compelled to share their builds? Or do you think they will just forget it? Why not just not respond unless it's something positive? People who are newbies deserve every answer from every angle.
Not everyone is fortunate enough to afford Dougs or TTIs.
Speed bumps are the worst almost exactly where the flanges are, because the frt on most rides will jounce the most after going over it, and they are directly behind toThat’s not true at all.
