Doug's Headers Catalog

Doug's Headers Catalog - So have at it boys, which one. My question is who may have advice on getting the z bar installed? I used hooker super comps on my cuda. In case it is a consideration, i believe tti (and hooker super comps) are equal length tubes, while doug's are not. A buddy has doug's on his charger and they fit good, and he is not concerned with the possible hp loss of unequal tubes. Next weekend i will find out if there is any performance difference with the bigger tubes. Some info says i must use 2 primary tubes as these 451's are 1 3/4 primary. She's a little loud in closed spaces, but once i'm heading down the road at 2000rpm, it's as quiet as can be in the front seat. Definitely need a plan and possibly modify the linkage to the fork. Headers by doug was the first name that he used making headers out of his muffler shop.

Fyi, i had to clearance the right side of the lakewood bellhousing. I've got doug's 2 headers on my '70 satellite with a 440. Sits very close to steering box, and of course the starter is trapped, but doug's fit very nicely. Definitely need a plan and possibly modify the linkage to the fork. Hello everyone, getting ready to drop my engine into my 70 road runner. Those header tubes eat up a lot of room. A buddy has doug's on his charger and they fit good, and he is not concerned with the possible hp loss of unequal tubes. A lot of conflicting info on line. Having gone though what i've gone though with the headers, i would have just done manifolds. I just got a set of doug's d451's for my charger.

They Made A Few Of The Original Designs, But.

I am liking at 2 primaries, tti are nice but a big buck to spend especially ceramic coated. Also, my headers rubbed against the steering box, and had to be shimmed over. I run 2.5 duals with flowmaster 40 series. That explains some of the fitment issues.

I Also Didn't Need 2 Headers, But That's What The Engine Builder Ordered.

I just got a set of doug's d451's for my charger. I used hooker super comps on my cuda. So have at it boys, which one. But, the doug's headers fit without bashing the hell out of them, and the quality is excellent.

As The Header Business Grew It Became Doug's Headers.

I've got doug's 2 headers on my '70 satellite with a 440. I can get dougs coated for almost a third of the cost and just as great construction. Fyi, i had to clearance the right side of the lakewood bellhousing. Hello everyone, getting ready to drop my engine into my 70 road runner.

Summit Says Shouldn't Be A Problem.

Some info says i must use 2 primary tubes as these 451's are 1 3/4 primary. She's a little loud in closed spaces, but once i'm heading down the road at 2000rpm, it's as quiet as can be in the front seat. Having gone though what i've gone though with the headers, i would have just done manifolds. I have doug's headers and was test fitting the passenger side.
