Stainless,...... I wish Joe ! I put everything I had - and more - into that car the last time I restored it. This will be the last set off headers I ever install into 'Mean Green'.


Thanx for the PM Don,....... I send a quick response last night. Trying to organize things a bit here so I can accept your offer.

Re: Dyno Don's Headers

I have a set of Hooker 2055's on mine that are HPC coated from a company here in Utah. 8 years now and no rust except where the AIR tubes broke and had to be welded.

Re: Dyno Don's Headers

do you have decent clearance with the starter and that oil pan? I have dons headers too and would like to run that pan but was afraid my aftermarket mini starter would be too big.

That's a nice oil pan.

Most people don't have issues with the pan, if I recall most people (that) have issues with the left side hitting the frame.

Re: Dyno Don's Headers

After seeing the pics I had posted back in April I got a message from Don offering some assistance with my headers. I was glad to accept about 1/2 of what Don proposed and promptly shipped my headers back to him.

After completing the proposed work to my headers they were returned to me in the time-frame that was presented before I shipped them back. I got them back in June but was unable to re-install till recently.

Here's what they look like now:




I do not know if the "fit" of my headers was ever evaluated while they were in Don's possession,.... I was insistent that the originally purchased headers
were returned to me to avoid any potential problems when re-installing them to the originally installed exhaust system. ( didn't want any sealing problems. )

While my initial dealings with regards to these headers was,...... less than satisfactory; I'm posting today to express my gratitude. Thank you Don for your unexpected offer to assist me and for the prompt return of my parts.

Re: Dyno Don's Headers

will the stock Y pipe bolt up to dyno don's headers or do you need a custom Y pipe?

Re: Dyno Don's Headers

It won't bolt to your stock y-pipe. Two options, order the Dyno-Don y-pipe or custom fabricate the ends of your stock y-pipe to fit the Dyno-Don Headers. That is why I offer for sale the flared ends on my site so you can have an exhaust shop use them to custom fit the header to your stock y-pipe.

Hows it going, im interested in ordering a pair of headers and single cat y pipe.
Currently i have hooker short tube 2055 and y pipe with air tubes cut off. What i dont like about the hooker headers is where it the meets the head the exhuast tubes stick up past the flange and has a small area for gasket to seal.
I rebuilt the 5.7 motor and stroked it to 383, all new internals. As to imformation you might need i have afr 180 heads, new poly motor mounts, and aftermarket oil pan (dont know brand).
The problem with my current set up besides the small primaries of the hooker headers and the flange not being flat after i rebuilt the motor the y pipe didnt meet to the header flanges due to poly monts, new heads and the space between oil pan and k member is tight making the y pipe need to sit a little lower. I had to chop the y pipe and extend it to meet the header flanges, week later i bottomed out and crushed the y pipe.
I want to fix all my problems at once and your headers seems like the best option. If you could message me back or email me at [email protected] it would greatly be appreciated.
Thanks, anthony williams

Re: Dyno Don's Headers

Question for those of you that have the Dyno Don headers on your car. Do any of your header tube start to glow while the holding the engine at 2500rpms or higher? I had an issue with the number 7 tube turning cherry red and narrowed it down to a bent exhaust valve. I had both heads completely rebuilt and now the engine is running like it should but while trying to force air out of the engines coolant passages, I noticed that the number 7 and number 8 primary tubes were starting to turn red. Engine runs smooth. Timing is at 6 degree BTDC. fuel pressure is at 40psi. Plugs looked grayish gold. Car is not overheating.

Do I have another issue here do will these tubes do this because of the thickness of them and material they made from added with the act that there is no airflow going through the engine while the engine is holding a steady 2500rpm for a couple minutes.

Thats what I thought when this whole ordeal started 6 weeks ago after I installed the headers and had the number 7 tube glowing. That turned out to be a bent exhaust valve. So, after pulling the heads and having them completely gone through, I put them back on along with a TPIS intake, SLP runners, AFPR and Bosch III injectors from FIC. I have the fuel pressure set at 41 with it idling with the vacuum line connected. its 50 or so with the line disconnected.

I ran the engine at 2500RPM for a minute to purge an air bubbles from the cooling system as well as listen and look for anything wrong. Thats when I noticed the same header tube starting to turn a pale orange. I looked at the rest and the #8 was doing the same thing.

The picture of the plug in my last post is from cylinder 7. I pulled a few other easy plugs and they all look the same as 7. I figured I would ask here since a few of you guys are running these headers. Just not sure if I have something wrong or if its just a combination of scenarios taking place that are making the tubes get hot. FWIW, I checked the temp of all of them with a point and shoot thermometer about 1" past the head flange and they were all within 30 degrees or so. The engine runs smooth and I out about 20 miles on it yesterday with no issues. I checked the headers throughout my drive and they were not glowing. I was running with no hood on the car.

Im just hoping that maybe, just maybe, the thin wall of the tubes and the lack of air flow while in the garage caused the back two tubes to do this.

What I cant have is these headers doing this in the middle of the summer while I am sitting in traffic. They will literally catch something on fire.

Re: Dyno Don's Headers

I really dont know. Maybe since you overheated the header tube before? How did that piston top look?

My #7 and #6 is doing the same thing and I'm pulling my hair out. I just ordered a new set of injectors to see if maybe some of mine are erratic.

I'm running stainless headers, but either way I don't think your problem is related to headers at all.

Are you sure the valve isn't too tight?

Common sense tells me it can't be a timing issue cuz it would happen on all cylinders. A fueling issue is possible if an injector is pooched, but I'm worried on my own car that it might be a valve issue.

Re: Dyno Don's Headers

When I did the valvelash setting, I went 3/4 turns. There were a couple that still needed a bit more after I fired the engine but those were not the #7 and 8 valves. I'd really like to pull the covers and adjust the lash while the engine is running but it makes a mess.

Been doing it that way for 20+ years. Just use cardboard, and don't rev the motor past idle.

You could also swap the injector to another cylinder to rule that out.

Like I said, I'm still trying to find mine but I suspect it's the injector. Although I'm tempted to do another valve adjustment this week just to be sure.

I just put new Bosch 3 injectors in this engine when I did the recent work. The injectors were bought from Fuel Injection Connection and were flow tested prior to shipping them to me. They were installed 3 weeks ago. Im 99.99% sure its not the injectors. Im 100% sure its not the timing. This leaves us with valve lash adjustment, bent valves or thin wall tubing on headers and lack of air flow to the rear tubes.

lash....could be and I will have to check on that

bent valves....no way since Ijust had the heads rebuilt

thin wall tubing and no air flow....could be and thats why Im here asking others who have these same headers.

If you held a steady 2500RPM on the engine while parked, would the rear tubes start to turn a slight silverish orange just at the bend in the tube as it leaves the head..

Re: Dyno Don's Headers

Why not,.......

Pulled Mean Green out of the garage for the first time and washed the winter layer of dust off it a few weeks ago. I saw this starting to really show up again last summer but didn't want to believe it was real:






Lucky if I put 2000 miles a season on it for the each of the last 4 years due to a bad clutch knee during the driving season. Really kind of sad that the steel parts I blasted and spay-bomb painted 6 YEARS AGO held up better than the finish on these headers,... that were fresh coated twice during that same time

It's not his fault ... at least my experience has been that NOTHING holds up long-term on headers, including ceramic. My hookers look terrible these days. I'm looking at new headers but there doesn't seem to be anything out there in SS these days. I won't use anything else going forward, might have to make them myself.

What size primary are you looking for? I have the SS 1 3/4" long tubes and they are great.

Probably those, but I have considered the 1-7/8" with all the extra air this moves over when I bought the 1-3/4" headers in 2002

Great to hear from ya, Joe.
