PowerPipe Exhaust Headers for slant/6 (Made In America)

[Mister Twister]

  The PowerPipe-DC headers we just built are a little differant then the other medium length tubes pictured in this thread. So far we can remove and replace the stock starter with ease, a little bend in the dip-stick tube worked fine, we will mount power steering unit today checking for clearance also. Still waiting on flanges ordered 2 weeks ago should see them by Friday he said ? We are going to install a choke pod on these and this will be sold as a kit for other headers not equipped with that. Just one more thing made by Mopars-N-More! See them soon Don

it seems that the two outer tubes come in at almost a 90. wouldn't it help if they came into the main tube at less of an angle? the diverter looks like a good ideal you never know till you test it.

Thanks cuda. I will have pics up this afternoon of the new design hope to get your input on these as well! There is an etch-a-scetch on A-Bodys forum. I think that's what your talking about, just don't have enough room to do that. Talk to you later Don.

The PowerPipe-DC true flow header design!!!

 Stock starter no problem. Alot more room in this area  

Water pump clearance.

Small stager for pipe entrance.



More complete connection will be done soon, kick down linkage, power stearing, carb and springs, ect,ect  Have a good night Don.

 A few more pics of the new style.

You can see the stagger better in this pic.

We are working on making are own  collectors. This also allows me to make the collector tube any size you might want! I will make the standard 3" for stock. We  will also sell these with collector size of  2"- 2 1/4"- 2 1/2" bolt on or slip on flange.

All pipes dead end at the same place.


They slide in very snug.

Straight in shot, nice range of entrance for pipes!!

Sweet collectors. Look lots better than what I have seen so far from other vendors. Keep up the good work and I hope you can get something going for the long ignored slanters.

Thanks grumpy!!! I working my ... off.  It will not be this crazy all the time I keep telling myself. Trying to finish this header design this week. Larry told me he shipped flanges Thursday. This will probably be the last after waiting almost one month. Thanks again for the info on flanges. I have a question what do you think about the header collector connection with no gasket?

[grumpuscreature]

If you are talking about the ones pictured, they are nice but cost quite a bit more than collector rings. I haven't had enough problems out of gasket style collectors to justify the increase in cost. I really like the heavy wall tubing you are using. There are 2 deal breakers with Hooker headers for me. One of them is the flimsy 18 gauge tubing.

[Mister Twister]

Yes I am talking about the ones pictured but this is what I'm thinking. I have the capabilities to make the collector the male end you see in the pic, and send the female collector tube with each set for exhaust connection?  This would eliminate the need for me or you to purchase the collector kit or gaskets anymore? Just toying around with this idea. Let us know what you think Don

We have received flanges and collector flanges for 2 1/2" & 3" The next sets I will make, 1 of them we are bringing to Charlies. The reason for this is to see if they will clear early style a body with a 170 in it and power steering box. I have asked all about preference size of collector, not much input, just going to make 3" for now. You can reduce them from that point. We will also make a 2 into 1 y pipe from headers for single connection to muffler. This will become 1 pipe near trans mount. Soon as we finish these sets they will go up for sale Don!!!

 PowerPipe-DC true flow header design (with merge collectors) We have tacked the front 1/2 together and the clearance is 1 ¾” over the power steering box. This should leave us plenty room for engine movement and drop for the 170.  The rear is completed and tacked as well, these will have a little better drop clearance of 2”. Both of these will still connect in the engine compartment. Rear is a stretch sitting just 2” over the center link. The front connects just behind steering box pointing downward just below and going with the angle of stock kick down linkage.  With new cables for passing gear and manual valve body cars, I feel we could come up with a better flowing design for all out racers. Not so many bends larger tube ect ect. We will have pics up soon Don.

For what it's worth, my personal preference for collector size is 2 1/2 inches. I don't do any racing, just street use.

[Mister Twister]

HELLO Grump. Yes your input means a great deal to me. You know, three different people has said the same thing. I will keep a couple of the 2 ½” collector sets  in stock also.  Talk to you a little later I hope. Let me say thanks for hooking us up with the flange supplier. He was one of the most professional people I talked to in a long time. He is already working on getting these for us soon!!!

Glad I could help. Let me run an idea past you. This may not be worth a whole lot since nobody else who makes headers has done it. Do you think it would do any good to run cylinders 1, 3, and 4 into the front collector and cylinders 2, 5, and 6 into the rear one? I know that would make the headers pretty much one piece and the primary pipes would need to be fairly short (kinda like what you are doing with these) just to fit it in a box for shipping, but it would give you an exhaust pulse every 240 degrees instead of being scattered all over the place like we have now. Would it be worth the hassle?
