Because putting on headers is really stepping out

TTI. Best fitting headers I have ever installed. Expensive, but worth it.

A few TTI people say the best they ever installed, but without saying what they are comparing them to. ?

I only say this because I can't imagine a "better" fit than Dougs d452 fit if you want 2" primaries, for RB B body. $200 cheaper than TTIs for the polished ones anyway.

Exit1965...I'm comparing them to Hooker 1 7/8" Competition and the Hooker 5209 2" Super Comps. I had both on 440s and 383s in my '70 cuda and the 2 '69 road runners. Also had a pair of no name 1 7/8" headers that were exact copies of the Hooker 1 7/8" Comp headers.
The Hookers always seem to interfere w/ the steering components. Whether it be the actual steering column or the tie rod ends. One set sat right against the torsion bars.

I used a pair of TTI 2" to 2 1/8" step headers when I put Indy heads on my 440 and they fit GREAT.
Learning from that, when I went to the hemi, I bought TTI's 2.25" primary 4" collector headers and they fit GREAT also.
I have a pair of Hooker 2" primary Super Comps for a hemi hanging up in the shop, but have yet to use them.

Never used Doug's, but heard good things about them.

My 1-7/8" Super Comps are against one of my torsion bars too.....
This on a 70 Charger RB, 906 heads.

This sounds crude and like something you might be scared to try but it worked for me...Get a ratchet strap and wrap around the collectors on both headers, so when you tighten it up, it draws the headers closer together and off of the torsion bars. If you don't have a crossover in your headpipes, weld a strap across the headpipes to hold the headers in that position. If you do have an H pipe, shorten and re-weld it. Remove the ratchet strap and drive it. Eventually, they'll stay that way after heating a cooling several times. Worked great on my dad's road runner. Only other option is to nearly remove the engine to get the headers out and beat the crap out of em w/ a hammer for clearance.
Did this almost 10 years ago to his car ('69 road runner, 440-6 w/ 906 heads) and never so much as hurt a header gasket...one thing I kinda figured might happen.

I myself use headers as I like the bit of performance it gives. But nothing wrong with exh manifolds if that's what you like. There are many very fast cars running exh manifolds. The FAST and Pure Stock classes are full of real fast cars running exh manifolds. Ron

I will say when I see pics of Gus's eng on his 64 Plymouth with his Doug headers they look a lot like my TTI's. And the Doug headers I see on cars look like a great fitting header. Myself I have not used Doug's but I do love my TTI's. Course that don't mean Doug's are not as good. I think both Doug's and TTI's are good fitting headers. Ron

all headers fit, you just have to take your time. TTi's are stupid expensive. I like Hooker Super-comps they are 2 piece, easy installation. But I have also used Summit cheapo's w/ no issues at all. These are cheap summits w/ PS

I concur...headers capture the starter.

Just be sure they have a thick enough flange on the cheapo headers. I hated the ones back in the 70's that warped and leaked with the very thin flanges. I know my TTI's have the nice thick flange that looks like a 1/4" thick. I can say they have been on my car since 2011 and still have the same header gaskets on them as they have never leaked. The Hedman headers I ran on my old 440 worked ok but the flange was not as thick as the TTI headers flange. Ron

ron, i have found on the cheapo, thin flange, headers, if you drill the one hole bigger on each attaching section, and cut the attaching strap from each pipe pairing, using a premium gasket, those will seal fine. i "stole" that idea from mr. pbody a ton of years ago, and still use it with great results !

In my case, I'm comparing to Hooker Comps and Super Comps. Good headers, but the TTIs were SO nice. I bought a complete 2" primary TTI system, cylinder head to tail pipe, for my '65 B Body and could not believe how well it fit and how easy it was to install. High quality, also.

Never tried Dougs, so I don't have an opinion on them.

What are your needs? I.e. what diameter?

Fairly stock motor?

Race motor?
