I ordered a set of headers from don. They're awesome! I had a set of Edelbrock TES headers that were 1 5/8. Dons have more clearance everywhere and they're 1 3/4. They went on super easy and are an awesome product. I know this has been discussed a million times. I just felt it was appropriate to give credit to a well designed hand made product.
for what it's worth I have an 82 ta w a zz430 clone and a pro flo XT and a manual trans. There was even room for the mechanical clutch linkage.

About 4.5 months. It was worth the wait. Don kept me informed of the delays he was hitting and was really cool about letting me know where he was at w them.
Looks like he’s done a little updating since I got mine. He used to just put a little tack bead between the the tubes where the y-pipe runs parallel before merging. Now he has a strap but it still only has 4 little tacks holding it in place. If you ever hear a maddening metallic rattle from the passenger side that’s your source. It won’t be obvious just eyeballing it. Super easy fix, just weld it back together. With all the heat cycling it’s bound to crack the welds. Mine took several years to happen.
Yeah, I'm really psyched w them. I wish I got these years ago. The bolts he recommends had great clearance also. I had to grind 2-3mm on one washer. That was the only issue. I reused my aluminum d port gaskets and they seemed to sealed up well again.
I am currently running 2 sets of Dyno Dons and an old set of SLP headers. The SLP’s are the best there was and the Dyno Dons are the best there is now. Recently sold my car that I was running a set of Edelbrock TES headers (had the cat back too). I would rate the Edelbrocks as 2nd place to SLP from what was available back in the day. The Dyno Dons are really awesome headers. Well made and a great fit.
It sounded good w the Edelbrock stuff. I needed more flow. The old stuff is all for sale. The headers I had ceramic coated. It's all in good shape w no leaks I bought it all new in 2002(ish)
Y pipe Tes next to dons Edelbrock muffler/tail pipes.
Car must have sounded great with the Edelbrock catback, they had such a nice sound. And today rare.

There were two generations of Edelbrock catback systems. I'm going off of memory here, so forgive me if I'm wrong... the RPM muffler was a bit on the mild side, but sounded very good and somewhat unique. That system was also sold with stock appearing tailpipes, which I liked. The later system used what they called an "SDT" muffler that was much louder and sounded a little "flowmastery". That system was sold with some nice stainless slash-cut tailpipes.
I had two of the early systems and one of the later systems (still have the later one installed on a car). I think i preferred the early system.
I have only heard the RPM, I saw the SDT in Summit and Jegs but never heard any. I had an RPM on my Dad's '93 S10 with the 4.3, it made it almost sound like a little V8, it sounded great!
I ended up removing the muffler and putting on a spintech w dual 3 inch outs. I felt the Edelbrock was a little too mellow. I've had spintechs an a few other vehicles and been happy w the performance/sound and durability.

Someone mentioned Don headers and recommended them to me how do I find or where do I go to inquire a set of headers along with Y pipe for my 82’ Third gen??

Not being mean, but he was literally the guy who replied first in your other post asking about headers. Username @Dyno Don on the forum here.
Yah, contact don or go to Top Down Solutions. They're on the website with options and pricing. Just a heads up, if the 82 is a manual dons header fit the mechanical linkage. Most other headers dont clear it well. Edelbrocks also do but dons are much better.
And as an update to this post 3 yrs later, I still think his headers rock, even at 8lbs of boost and 550hp!
Fortunately and unfortunately, you can't see how well they've held up as easily anymore!

I could've sworn I read on one of these threads that he did long tubes as well but I haven't been able to find anything on them since. Can anyone on here confirm whether or not I'm remembering that incorrectly?
I am considering buying a set of these headers. Also his dual cat pipe, dual cat collector and 3" intermediate pipe. Has anyone installed this whole kit with dual cats? Are the diameters right for the factory cats? Is the output on the dual cat collector 3" to match the intermediate pipe? What muffler fits well with 3" intermediate pipe?
