DynoDon headers
Nothing lasts forever so with that being said.......
To anyone interested...
My plan is to make 10 more sets of headers
but the header shop wants me to pay for the material
in advance. The only way I can do that is "IF" I get
at least 8 orders for them.
So if you have been on the fence about getting a set, now is the time
to act and get your orders in.
PS: If not, that will be the end, I will hang it up and they will no longer be available.

Re: DynoDon headers
How about a set for my 1989 IROC Z Vert, AT, AC. Can you build a set for a to be installed, L98 or L31 , including AIR fittings and the appropriate EGR supply port? Would the L98 and L31 uses the same header? Are they stainless steel? Ceramic coated? 84780, Utah Price?
Thank you!
Thank you!

Re: DynoDon headers
Interested. Do we place the order through "Topdownsolutions"? And is shipping to Canada an issue?

Re: DynoDon headers
TDS site shows the "Corvette style EGR Style Flange" as a $ 40 option, "replaces one AIR Tube" No more? It's what I, and others might need, to put an L31 in a third Gen F body. right?

Re: DynoDon headers
Any chance of getting front mount turbo headers/Downpipe for a 92 5 speed (firebird) tpi?

Re: DynoDon headers
I would like to order a set, but for my needs, I think I want SMOG/Ca legal headers or none at all.
Of course, I do not expect Dyno Don to pay cali, maybe, $ 50,000 dollars to "test" and "certify" his product!

Re: DynoDon headers
I’ve been interested in a set of headers for a mild 327, y pipe into single 3”, and intermediate pipe with no converter provision. I was going to wait until fall but I’m glad saw this post. Is this still available and approximate cost?

Re: DynoDon headers
I have ceased making them for now, Top-downs solutions will be putting together a group purchase.
If enough participants join I will consider another batch.
However, you will not be required to purchase from them.
I might still be available direct.

Re: DynoDon headers
Sounds good, put me in line please.
I have a 91 B4C that the headman headers will just not work on the driver side. Ended up putting manifolds back on.
the header hits the oil cooler lines.

Re: DynoDon headers
I would like to thank Dyno Don for creating these headers and making them as long as he did.
It is too bad someone couldn't continue to make them in the future for those of us who long to buy the best but can never seem to pull the trigger.
Since our cars are between 41 and 31 years old, parts are going to get harder to find as each passing year goes by.
Thanks again Don.
Maybe I'll get lucky and locate a used pair some time in the future.

Re: DynoDon headers
Hey everyone, I emailed Dyno Don to see about getting a y pipe and headers made for my 3rd gen camaro with an sbc. I want tap sets but he said if he gets enough people he would look at making more sets so anyone that wants them should reply to this thread. Thanks!

re: Single vs. Dual pipe exhaust flow, which is better?
Hey there Don, I am curious, are you able to fab up some turbo manifolds? Planning a 406 tpi build with either single or twin turbos, account is too new to pm yet. Let me know, thanks!

Re: DynoDon headers
Id' be interested in a set. Not swapping my motor for another year and a half tho. Sad to hear this option is closing. I may just gamble on a set for my planned setup if there's another run..
