Dougs Headers

by **dave-r** » 07 May 2007 8:27

Fit GREAT!

Clearence for everything.

The torsion bars are not in yet but I can see there is plenty of room for them.

Also plenty of room for the steering box and starter motor. It looks like power steering and a full size starter motor would fit fine too. All this with 2-inch primaries.

The price of these headers has gone up since I bought mine but all the same they are a lot cheaper than TTIs.

I would never go back to hammering/grinding cheap headers like Hedmans again. Not even if you paid me.

Wait until you have assambled the steering shaft.... :twisted:

I am just joking. It looks great!

Plenty of room for the shaft and even that horrible coupler thing that I hate and hope to get rid of with a Flaming River shaft. :wink2:

Hey, don´t pick on the part of my challenger I like the best! :evil:

Looking good, Dave. I did have clearance problems with the TTI headers on the passenger side..... had to go to stock motor mounts instead of Shumachers and drop the block a bit to get them under the torsion bar. If I have cause to change them out, I'll go to Doug's for the next set.

Great choice Dave. :thumbsup:

I'm not sure this headers will fit with my future hemi, the builder John, told me that TTI will fit without problem using his engine mounts.

Anyway the headers will be 2 1/8, more difficult than 2".

Let us see it when you have all installed.

I have a clear line of sight through the holes in the k-frame where the LCA pivot sits to the hex hole in the trans crossmember. The headers do not come close.

These are stock 440 engine mounts. I use a torque strap to stop them breaking.

Hemi headers are completely different of course. Spaced differently and at a different angle.

As far as I know Dougs do not make Hemi headers. For a Challenger at the very least.

OK I have the torsion bars in now. This is the closest the headers get to anything. It is about 3/8ths by the look of it. On the drivers side. The passenger side is better.

And remember. Those are 2" primary pipes and 1" thick torsion bars. Not your wimpy stock bars.

It looks smaller in the photo so either the camera lies or it is my eyes faulty.

by **fbernard** » 16 May 2007 17:15

Cool! Having a clear line of sight to all the spark plugs is already a good improvement over some TTI's...

by **dave-r** » 16 May 2007 17:41

5 of the 8.5mm MSD spark plug leads are the long straight type. All four on the drivers side are like that of course.

Only #8 on the passengers side is the straight type. The front three need to be the 90* type. No problem as the boot ends are only a few Dollars.

The only plugs that did not screw in first try were cylinder #s 3 and 6. The rest were no problem even with my clumsy fingers.

hi Dave

looks good and appear to fit good also!

how about the ground clearance compared to other headers?

think you these can work in a car with lowered front suspension?

thanks

by **dave-r** » 18 May 2007 14:48

I don't know what the ground clearence is but i don't think you could fit headers any higher up?

My car is on jack stands so i can't measure that.

maybe you can judge by the photo from under thecar? You can see the chassis rails.

by **Eddie** » 18 May 2007 19:35

As long as the Collectors are "Clocked" where the apex doesnt' point towards the ground, you should be fine. The collectors are the first to catch something. TTI's are clocked the right way, I'm sure the Dougs are too? I scrolled up. Yes they are! This Really helps!

by **Misaeus** » 19 May 2007 17:29

thanks

i know some headers are good for power but not good in fitment and ground clearance...

your Dougs appear to be well designed.

by **dave-r** » 19 May 2007 17:36

Tuned equal length primary tube headers are best and make great power but if they are in the way of everything or sit too low they are not really usable on a street car.

How true Dave! I remember the "horrible" Hooker Headers I had on my 1973 RoadRunner. They helped with the power, sure, but they "scrapped" the ground one too many times. After welding, it happened again in a few weeks! Then I went back to stock manifolds after that experience.

hi im mounting the tti on my challenger i orderd them with 3" collectors
i have a 3" exhaust system but the reducers ive got the tube was only 2.5"
is this the wrong redusers or do you have to special order if you got a 3" exhaust??

by **dave-r** » 29 May 2007 19:47

I think you have to order reducers if you need them. The 2.5 inch ones come with the headers as standard. Along with gaskets and bolts. All in with the price.

I got 3.5 to 2.5 reducers with my Dougs headers as well. I was not expecting them and I don't want them.

I am currently looking for 3.5 to 3.0 reducers in Stainless Steel for mine. Cannot find any at the moment.

www.stainlessworks.net makes them in virtually any size you want. Then simply band clamp them with TTI's or Doug's band clamps, or better yet weld them in.

It didn't "highlight the website!

Nice one Eddie! :thumbsup:

Very smooth transition between the sizes. :nod:

The link works now Eddie. You didn't have a space between the end quote bracket and the first "w" in "www". :wink2:

by **rookie** » 30 May 2007 14:43

ok i was at an ordinary exhaust shop today and they will make a pair for me. i just brought the one i got and said i wanted them in 3" instead.

im picking them up to morrow if the quality is good you could check a exhaust firm near you

by **plum-crazy** » 17 Jun 2007 5:46

Hi Dave.

Finally could you checked the ground clearance?

by **dave-r** » 17 Jun 2007 12:20

The car is still on jack stands with no wheels. I doubt very much you would get better ground clearence.

I just went down and had a look at them.

Working the other way (from the chassis down) they hang 2.5-inches below the chassis at their lowest point.

by **Eddie** » 20 Jul 2007 19:24

Just ordered a set of 3/8 12 pt. Stainless ARP fasteners for my TTI's which currently use a plain steel hex head and are beginning to rust a little,(can't have that!). :mrgreen:
