Hey IROC406, the Dyno Don headers without air tubes were going for about ~$620 when I ordered as part of this group purchase.

 

If another order is made I would love to be on the list. Late to the 3rd gen party.

 

Got mine today! A huge shout out to @Dyno Don for making these, and to @lonsal for processing my order. Great customer service, and packaging was top notch. They made it all the way here to the east coast of Canada with hardly a mark on the boxes. Can't wait to get started on this project

 

Nice!!! Can’t wait to pick mine up soon hopefully. Headers, Y-pipe, and full catback exhuast should make for a fun summer 🔥

 

Headers and Y pipe arrived today. All's I can say is WOW, Don has done an Awesome Job!!!!!
Thanks again Don it was a real pleasure doing business with you......

 

Picked up my headers, y-pipe, and 3” I-pipe today! Can’t wait to get them all installed. Thanks Dyno Don and also Lon at Top Down Solutions!

 

Looks great!

 

Hey guys, I also received my Dyno Dons and got them installed! Did anyone else run into fitment issues specifically on the passenger header? My collector flange runs into my k member and prevents me from mounting my y-pipe. Maybe @Dyno Don could comment on if he's ran into this before? 89 Trans Am with 60k miles zero accidents.

 

What kind of shape are you motor mounts and trans mount in? If they are rotted, smushed, and sagging maybe your engine isn't sitting in its factory correct location.

Rubber parts like mounts and bushing are out of sight and out of mind and get forgot about and overlooked.

 

Hi Airwolfe,

Original motor mounts as far as I'm concerned. The trans mount is only a few years old as I replaced it when I did my T56 swap. Has anyone had good luck replacing motor mounts with the engine still in the car? I don't have access to a cherry picker unfortunately. Thanks!

 

Now I'm just taking a wild guess at motor and trans mounts. Ain't saying for sure that is the problem.

 

When I pulled and rebuilt my 88 LB9 back in '17, I decided to install DD headers. As I recall, it was tough, but they did install with minimal clearance. I had new motor mounts and, if I recall, I had to hoist the engine just a bit.

 

Check the Group Purchase board,new message.

 

New engine mounts were not good enough in my case,..... I still had to remove the new stock engine mounts and replace them with aftermarket POLY bushing engine mounts to (help) get the clearance I needed.

 

Well so far I've determined the following:

• Replaced passenger side engine mount with BRAND NEW rubber engine mount - Header still sits on a-arm mount
• Replaced BRAND NEW rubber trans mount with ENERGY SUSPENSION polyurethane trans mount - Header still sits on a-arm mount
• Knock sensor pulls up to 20 degrees of timing due to my header sitting on the a-arm mount

Has anyone else installed their Dyno Don's from this purchase order with success?

 

POLY engine mounts sit higher than stock rubber....... I had almost new engine mounts at first & clearence issues; installing POLY mounts made the biggest difference in getting the engine lifted up enough. ( I still have to grind / shave some of the frame too ). Yes; I asked about clearence using stock mounts before the header purchase & was told new mounts would be fine; but the drivers side header hit the Cradle & I had to swap the mounts with poly insert mounts ---- > WHILE the engine was installed. Installing mounts when there is no engine in the way is prettty "easy", but it's a PITA when the engine is still installed. ( I was sooo pissed ! )

FYI: * I installed a second set of DD headers on another car and in that case the PASS side header was the problem.



Drivers side orientation:


Passenger side orientation:


Double check that your engine mount 'clamshells' are installed on the correct side of the engine bay. I don't have the part numers handy - but you can search the forums for my older posts/pics that should show the part numbers.


Hold onto the rubber tranny mount,... you *might* want that to re-install once you get the header problem resolved. ( POLY tranny mount works good, but causes a very rough ride ! )

At this point every Thirdgen has bounced, bent, shifted, buckled, crashed in it's very own specific way and every one will be different, just like every header is gonna' be different. All it takes is driving into a curb and that whole engine cradle can/will shift. Change the tire/wheel maybe a bent tie rod and it all looks fine, when in reality the steering box twisted the drivers side fame rail on impact and shifted the 1/16": tolerance at the engine cradle-to-frame alignment pins from left-to-right....... **** happens.

With any luck,... this message will help in some way.

 

I too had the clearance issue on the pass side.

New rubber mounts and a spacer under the poly trans mount raised mine but, like above, I still had to grind a bit off to get acceptable clearance.

 

Hey Naf,

Thanks for the response! Did you order your headers on the last group purchase as well?

 

Are we doing another group purchase?

 

I haven't installed mine as of yet. I'm also curios to hear if the fitment issue is prominent in this "batch". What seems to be the best fix or work around in these cases?

 

FYI, You're talking about a very small sample size. Only 3 orders have shipped so far from the latest batch of headers.

Lon

 

I spent all my cash on stuff the car had to have during the first round. Im ready this round.

 

mine were installed several years ago

I'm with JIRI.

who knows how much the pieces/parts in our cars have changed their spatial relationships since the original Magnum PI was on

 

Probably way late to the party but if these headers are available I would like a set

 

I am interested in buying a set of your headers no AIR tubes and am prepared to order

 

I'm a bit late on this post where can I purchase for my 87 camaro 350

 

Stay tuned I am working on a plan to get some more made.

 

Good luck many of us are still waiting I hope Don makes more soon also

 

Good news!

I know you've said "no" in the past, but any interest in doing a 1 7/8 version? I think there would be demand since there aren't other good options out there for stock K-member.

 

Sorry. no, 1 7/8

 

Danggg i wanted some dyno dons headers but aeems impossible to get

 

I presume they are long tube? Price to 06385 please.

 

They are not long tubes

 

Thank you Don.

 

Don, are you going to be making more headers? Id love to buy a set.

 

I would be on board too if you decide to do another batch.

 

I would like a set also if you are still making them.

 

Still working in it.

 

Do you make a set with air tubes?

 

I’m interested in a set of headers with air tubes and a y-pipe.

 

OK I have have a process in the works to make some more.
When ready I will post here.

Thank you all for your interest.

 

Count me in!

 

Im still interested and have been waiting don’t forget about me Don lol

thanks

 

sign me up for a set

 

Just posting to show interest. ....working on getting another thirdgen. Haven't closed the deal, but if I do....I'd love a set.

 

I'm interested. need a good set of headers
​​​​

 

Also interested in a set of headers + dual cat pipes (plan to go true duals), ideally without air! Please add me to the waitlist

 

Good news ...

They are being made
as soon as they are ready orders will be taken.
need to get the Y-pipe jig made up.

 

Sweet!

 

Awesome! Patiently waiting on the word to put an order in.
