Dougs or TTI headers...Any preference? #486007 10/02/09 09:43 AM 10/02/09 09:43 AM

('70 E-body with 440/727...manual steering and brakes, No AC. Factory iron heads, but possibly a pair of Indy SRs or Edelbrocks down the road. Car currently runs deep into the 11's in 100% street trim.) The car has a 3" TTI X-pipe system on it, so I considered TTI headers. That being said, I have heard both good and bad about their headers. As an alternative, I considered Dougs headers since they have been around forever and they have a real good reputation. I'd most likely be considering 2" primary headers. They would be coated as well. Any feedback on either vendor as far as fit/finish/etc...? As of right now, I'm leaning towards Dougs headers. Thanks in advance.

I found a local place that does high temp coatings, so I'm going to order bare headers and get a colored finish. I don't think the factory applied coating held up well on my TTIs. If price isn't a concern go with the TTIs and order their collector kit. Everything should bolt right up. According to TTIs site, the collector adapter kit is supposed to be included with the headers. Some vendors will try to charge you extra for it, so beware. I'm going to try to squeeze a deal out of TTI when I go to the Fall Fling. Doug's can be had for $640 coated/$500 uncoated through Jegs. You'll likely need to have a shop fab the collector tie-ins though. Last edited by 64Post; 10/02/09 07:14 PM.

My vote goes to Doug's. I'd be checking into the fit with the SR's though - don't they have a relocated exhaust in order to fit a-bodies ??

The two things I've run into with them are - I had to clearance the power steering box about 1/8" Basically I ground off some cast letters/numbers. I had to buy plug boot insulators to keep from smoking spark plug boots on a couple of plugs. After I put them in someone came out with ceramic boot plug wires which I would try if I had to do it over again.

I have manual steering and angle plug Eddy's, so the Doug's are starting to look better all the time... Thanks

The headers fit very well and I only had to clearnace the one pipe slightly on the driver's side at the torsion bar. Probably because I have the larger than stock bars installed. I think these are the best fitting header I have ever installed. Here's a shot of the driver's side top. Sorry, don't have any others presently that show them off any better. 5520904-HPIM2759.jpg (234 downloads)

I love my D452 Doug's headers They fit almost perfect(had to remove the pitman arm grease fitting and ding the tube near it about 1/4".I used the AR Engineering motorplate and have an 11" 143 tooth wheel with a Dakota factory ND starter and my factory Z-bar fits good.I had to trim 1/2" off the lip of my safety steel blow-shield on the left side for the #7 tube.These are the best 4-speed headers I have ever seen.I am using Indy EZ heads with Firecore 50 wires and they don't touch the headers anywhere(thanks Rick) Gus 64 Plymouth Savoy 493 Indy EZ's by Nick at Compu-Flow 5-Speed Richmond faceplate Liberty box Dana 60

My brother found a local shop in St. Louis that does hi-temp coatings as well. I'll have to look into that. Has anybody used Dougs headers and TTI exhaust? It would be nice if TTI's adapters would work with Dougs headers without going to the exhaust shop.

No extended warranty on factory ceramic coating. 1 year, that's it. They fit well and appear to be built well. Next time I will get them bare and have someone else apply the coating.

Blues_Cuda OP master Joined: Aug 2003 Posts: 3,896 St. Louis, MO	northcoastmopar- That is what I was afraid of. I'm thinking about getting the new headers coated black for my wife's car. Her car is stored in the garage and rarely driven in the rain, but the drastic temperature changes we have in St. Louis can make the garage sweat pretty bad. I've seen the engine literally wet from sweat at one point. I wonder if the locally owned shop can apply a better coating than TTI or Dougs though?

The problem with getting them coated on your own is that the coaters will almost always want to acid dip them to ensure all the rust is gone and then the coating process costs more just because its a one-off job. You'll end up spending about $200 more than a set of factory coated pipes. All that just so you can choose between black or silver ?!?!?
