Re: Dyno Don's Headers
Bit off topic, but hope you can help.
I have a Right Hand Drive Camaro and have a problem betting headers that will clear the steering shaft on the right hand side. In particular tubes 1 and 2 are a problem.
I notice pictures 49 and 50 in your photo bucket account have headers where tube 1 goes over rather than under, which would be good for me.
Can you tell me the brand and model of these headers (don't look like Dyno Don's) ?
Cheers

Re: Dyno Don's Headers
Don - do you have a black coating for those? I am thinking about putting headers on my car, but I am hoping to keep it looking as stock as possible. Also on my car, which is a Crossfire 305, the location of the o2 sensor is in the Y pipe. Is it possible for you to make these with the o2 sensor bung in a different location?

Yes, they are available in black.
The 02 can be in a different location.

Re: Dyno Don's Headers
Will these fit a 1983 LG4 Trans Am? Fit without modification? I have a single cat and the 0'2 bung is on the driver side manifold on my car. How much is a set of these? Thanks in advance.

Re: Dyno Don's Headers
I think '83 had a square converter flange on some models.
PM me for price with your details. (smog, zip etc.)

Re: Dyno Don's Headers
i will also comment on dons headers, they are great thick flanges and absolutely no leaks, running the earls gaskets he recommended and also ordered mine with the dual cat y pipe, fairly easy to install and changing plugs is easier than my old hookers, i noticed on mine i did have to bend the break lines coming off the master a little but nothing major and can be expected, A+++ to don his headers are great and so is customer service

Re: Dyno Don's Headers
Do you think the dual cat set up is worth changing to from single??... my current exhaust is single style but is a true butcher job with no cat at all.

Re: Dyno Don's Headers
i think if your wanted to run true duals it is worth it which is what i originally wanted but changed my mind and merged the 2 1/2 pipes together into single 4" in the diagonal under the passenger seat and am running a dynatech 4" muffler at the rear, sound is awesome and so much easier than duals

Truth is, a single 3" intermediate pipe flows as much air as the two 2 1/2" pipes. The choke point is the cat, not the intermediate pipe, or the muffler.

Re: Dyno Don's Headers
Just wondered since it is pretty much totally gonna be replaced if it would be worth it to add the split cat y-pipe or just go with the standard set up my car came with as the cost isn't going to really be all that much more moolah.

Re: Dyno Don's Headers
Dang guy what are you 60? lol I'm just playing with ya... I am definitely not a kid but I'll take it as a compliment. I am not nearly as new to this board as you may think either(2006 maybe?). I plan on putting a converter back on my car before the exhaust is done. As the car sits there is a terrible header-back system full of bad welds misaligned pipes and no cat..

The stock "y" pipes were 2 1/4". a single 2 1/2" cat can handle that with no chokedown.
If you have a 2 1/2" "Y" pipe, then you can go with either dual 2 1/2" cats, or a single 3" cat, and there will be no difference in the flow.
The problem with the 3" cat is ground clearance. I went with SLP 1 3/4" headers, and a 2 1/2" "Y" pipe into dual 2 1/2" headers. I'm happy with it, but the dual cats did cause clearance problems with my subframe connectors.
I went with Spohn weld-in subframe connectors, and they clear just fine.

Re: Dyno Don's Headers
I'll also vouch for Dyno Don headers. I was the first person in my car club (NYTHIRDGEN) to put them into my car back in 2009. Since then, 4 more people in my club have put them in. 2 people upgraded from Edelbrock headers. I actually passed up a set of SLP Tri-Y headers (Same as used on the 91-92 Firehawk) just to keep the Dyno Dons in there. These are the best headers you can buy for our cars. They went in easy and have amazing clearance everywhere. My only gripe about mine, was that I wish I had ordered them without the AIR pipes. Oh well, live and learn.

Re: Dyno Don's Headers
It's not all peaches and cream for everyone. Maybe things were OK back in 09' but the recently produced headers have been a problem for me and for others.
I've installed Dyno Don headers & the drivers header hit the K member - HARD. I'd be inclined to believe that this might have been a 1 time thing,.... but I had the EXACT SAME problem with 2 cars using 2 completely different sets of DD 1- 3/4" headers ( without AIR ).
https://www.thirdgen.org/forums/exha...dyno-dons.html
At a MINIMUM expect to be forced into installing Poly Motor mount inserts. Even after the inserts were installed; BOTH sets of Dyno Dons headers I've installed hit the drivers side K member. At least you've got some warning and can prepare in advance.
This way MY experience with DD 1-3/4" headers. Your experience might be different.

Re: Dyno Don's Headers
Ok, I have been on vacation and came back to a bunch of problems on this end.
I am dealing with each as I can.
I have a car here to tear down and recheck things on this end, bear in mind I have sold a bunch of these and only a few issues.
I will get into it as soon as possible to see if any thing has changed.

Re: Dyno Don's Headers
Yes you have, I emailed you several times.
I am not ignoring you never have never will, I am a one man gang and I am doing all I can on this end. You seem to be having issues that others have had and fixed by swapping the mounts.
If you have tried that, then bare with me until I can get this car apart and see if anything has gone ary on this end.
If you have gotten parts that are not right I will make it good, but don't need to get angree with me on an open forum.
You asked me some questions and I tried to give you some answers not excuses.
Remember there are a lot of these sets out there that fit fine.
I am very sorry you are having problems.

I have no room on passenger side, he has no room on drivers side. My y pipe hits the frame by alot . You know after dealing with so many people in the aftermarket since 95 when people tell me they are trying to help but are a one main army , Im sorry I really have nothing to say about that at this point. I paid you, and a good amount too. And all you have is excuses one after another. You told me on two occasions you had a car apart on the rack and would get right back to me , never did. I have the emails if I need to post them. Then the kicker here and #1 reason I am getting angry in an open forum is that me and john are posting about problems we are having and you dont respond back to us, but to someone else looking to buy a set of headers. Im about done with these things I have had two other sets on my car never the problems or agravation Im having with these not by a long shot. Next step is these headers are getting sold. Id send them back to you and let you deal with them but after two months and no offers from you to take them back and even consider looking at them or taking dimensions or pictures it seems like you have washed your hands of this. You want to talk about one man band? Well I guess I am too only I didnt make the money on this transaction like you did ,I lost it and then some.
Was debating between these and the hawks ones when I was going to purchase a set, should have went with the hawks ones all day. Called them up yesterday and actually spoke with the owner about this issue im haveing and where I am on this.To make a long story short he isnt going to let me eat crow if I have an issue. He told me test fit them if they dont fit send then back, but he is confident they will fit poly mounts and all. And if I do need engine brackets he has them. He said he will do what it takes to make it work. No excuses.
If I was the only one I would have pulled this motor a long time ago. But after seeing two cars not fit with all the supposed right parts and then fit somewhat with poly mounts you said was my problem at first, Im at a loss. Like I said big thumbs down to this whole situation.

I have a random car, I have picked a random set of headers, a random set of pipes, both single and dual and I am posting the picture of them all.
I also have a picture of the mounts showing the difference.
Everything fits just fine on this car, nothing hits, some spots are close, but nothing hits.
Right side
Left side from under the car with a light on top
Left side dual pipe
Single crossover
Difference in the Mounts
Camarorookie (Troy) was here and verified everything.

Re: Dyno Don's Headers
Gotcha. I have no idea where your headers are hitting so Im just poking around here.
Is there any way the trans mount is worn out or the crossmember could need adjustment to move the headers a bit?

Re: Dyno Don's Headers
I will make another y-pipe tomorrow on the same tooling your was made on and try that on this car.
That Y-pipe in the picture came off an '89, this car is a '91 (not that that makes any difference) they are all the same, but I guess there could be some various minor things.
I didn't have this car before to check when you said you had the issues (just got it apart today).

Re: Dyno Don's Headers
I will make another y-pipe tomorrow on the same tooling your was made on and try that on this car.
That Y-pipe in the picture came off an '89, this car is a '91 (not that that makes any difference) they are all the same, but I guess there could be some various minor things.

Darren:
Here is a picture of the crossover freshly made on the same tooling as yours,
it fits perfect.
Everything lines up as it is suppose to.
Unless something happened between here and there yours should be right.
You have to make sure those mounts are on correct.

Re: Dyno Don's Headers
I've helped Don install at least 10 sets of his headers on 3rd Gens and C4 corvettes and 8 of them had fittment issues due to clapsed motor mounts or the mounts are on the wrong side. I know it's frustrating, took me 8 hours to figure this out on my corvette, but after I did it took me 3 hours to install them. The headers are of the best quality and really increased my exhaust flow, I gained 35hp on the dyno with just Dons exhaust.
Be patient and work your way through the fittment issues. Sooner or later, the motor mount issue would have to be fixed anyway.
