Re: DynoDon headers

Hey Don,

How many orders are you ideally looking for before you start taking orders?

Re: DynoDon headers

I have to say, I ordered a set of headers from don 3 years ago and they are great. They have more clearance than any other header I've seen in these cars. They're extremely well laid out. They fit my d port fast burn heads perfectly. No issues w spark plugs. No issues w access to header bolts. The y pipe had plenty of ground clearance. They cleared the mechanical clutch linkage on my 82. Then I swapped to a t56 and used a quick time bell there was no issues. The ceramic coating has held up well. I really couldn't be anymore pleased. Anyone on the fence, go for it.

Hey DynoDon, I know this is an older thread and your original thread was older as well. But yeah, I also need a new Y-pipe for my 68753 Edelbrock headers. Shipping would be to Hubert NC!

Thanks for making one last batch Don! I put my order in on Top-downsolutions.com. I'm assuming the 8-10 weeks ship estimate is still accurate?

Re: DynoDon headers

Don, is the single cat y pipe listed on Topdownsolutions for the SLP headers what is needed to connect up to your headers or is it something different?

I understand it may not be possible to give a definite answer, but what kind of estimated build/delivery would be expected if we are able to get in on this group purchase?

You're right, but I think 6-8weeks might be realistic.
I have to have confirmed orders to get the material ordered.

Re: DynoDon headers

I'm looking forward to installing these my friend I both ordered a set. I currently have the Hedman set and they are very restrictive and get very close to the oil pan. Is anybody planning on using the exhaust setups from Hawks to go with these?

Re: DynoDon headers

OK, it's official. Our first Group Purchase for Dyno Don headers is officially sold out. Y-pipes, I-pipes and various miscellaneous items are still available. I have once again shut off the Dyno Don headers on my website. If there is interest in future in running another Group Purchase of headers contact Don or myself to get put on the list. Once we've received enough I'll turn on the option to purchase them again on my website.

Thanks to everyone that expressed interest in purchasing these and placed an order.

Re: DynoDon headers

What’s the lead time for these to ship?

I know and appreciate that @Dyno Don makes these by hand. This is truly a lost art that will probably not return in our lifetime.

I'm like a kid anxiously waiting on Christmas!

Re: DynoDon headers

Hey Mike,

For what it counts, I'm planning on pairing my Dyno Don headers + y pipe with the 3" Magnaflow catback. I haven't found too many pictures of the Hawks setup installed with the Dyno Don setup.

Headers for the GP are done. Y-pipes are being assembled to jigs and tach welded. Should be shipping orders very soon.

Re: DynoDon headers

I know I am late to this but what is the header price for 89 IROC? I have stock L98 heads. I see the Y pipe going for $310.
