Doug's Headers?

[mopar0166]

FIREFIGHTER3931 -

How about performance on my engine, im going from 17/8"/3" collector to 2 " primaries with a  3.5 " collector to 3" exhaust im guessing with it being able to breath easier it might help on torque

[firefighter3931]

What is the engine combination ;  heads/cam/compression etc....

Top to Bottom - Holley 850 DP MEc sec, Edelbrock Performer RPM intake, MSD IGN/DIST, Edelbrock ALum heads, roller rockers, Edelbrock performer RPM cam, high volume water water, alum housing, speed pro pistions, hp rods , int balanced stock crank, deep oil pan.  compression is 10:1 , running 3" exhaust currently. 

I know I could have a more aggressive cam, but it been good to me so far.

That should run fine....you have a good top end on the engine with free flowing heads. Typically a 1 7/8 header is the better choice but you won't loose much torque and probably gain some horsepower....a bit of a trade off. If you decide to build a stroker in the future you will be all set with the exhaust. 

I purchased the 2in TTI's for my old 446 and it ran great ; similar build to yours with a bigger solid cam. I knew that at some point I would be going stroker so the 2in was a good choice. The dual plane RPM intake is much better than what I had on the old 446 so the torque drop off won't be much using that intake manifold vs the single plane mine had (Holley Street Dominator)

Are you trying to see how low they hang?  On my car they are visible from underneath the car when you're looking at the car from the sides.  They're about as low as I would like them to be with the Hotchkis suspension doing its thing...

[mopar0166]

I want to see how close they get the cross members and how well they line up with the through the same.  I attached a pic for example, its not my car.

[mopar0166]

AH I said why not, I bough the headers and should be here Saturday

although, if people are looking for these, jegs said they couldn't get me a pair till May 31, I quickly canceled the order, cause summit had them ready to ship same day same price. 

[myk]

Good move, you'll love em....

[mopar0166]

got them, just waiting on my transmission to put them in, they look great. 

ill have to post pics when im done doing all my work, time is running out to get it done so ill be busy the next two weeks

[Derwud]

Went to Spring Fling, cash in hand and stopped at TTI, felt like I was bothering them, oh well.. Just ordered a set of plain Doug's so I can get O2 bungs welded in and ceramic coated.

[mopar0166]

Mine are beautiful, you will be happy , ive done as much research on them as possible and it dam near a set of tti I design

[Kern Dog]

The people at TTI seem to think that they invented headers with the way that they have theirs priced. Yeah, theirs are great but holy crap! $850 for headers???

[mopar0166]

still waiting for my transmission but once its in I cant wait to install them

I priced the TTi's that I needed at a grand.  Too rich for my blood...

[Derwud]

My headers are in route, all 10 miles.. I drive by the place every day!!

[mopar0166]

so my torqueflight will be done sunday, install Monday hopefully.

testing new elect harness tonght

new steering, and windsheld to follow all that along with some detailing.

[mopar0166]

Mine are in

Grade

Ease of installation - A ( took longer to my hookers out then to install these, very ease to put in place)

Room through Steering - A (free and clear, good movement of the steering components)

Room Around Torsion Bars - C ( I'm sure their will be some rubbing especially on the passenger side,  we will see what's happens during a drive.)

Product - A

Spark plug access - A ( I have angled plugs)

Access for mounting bolts B+

ceramic finish - A


Great product and highly recommended.

It doesn't look like anyone answered you so I will...  I was told no, these are separate companies. 

As for this thread I'm probably going Hedman or TTI.  At least TTI gives me a couple options for my 318.  For a 73 Dougs only lists a header for a 5.7L hemi, nothing that fits a 5.2L.  Is anyone running Doug's on a 318?  Mine has a Comp Cams Xtreme energy 20-221-3 cam, performer intake, 1406 edlebrock and straight dual exhaust now.  Just need to ditch the stock case iron exhaust.
