Here is a link to the thread with picture: http://www.thirdgen.org/techboard/ex...-4-header.html (1 3/4 Header Options)

Does that mean you are close to installing the headers on my car ?

Waiting for injectors and....emergency engine install.

COOL

One more happy thirdgenner here. Don's Headers and Y pipe are great. It made the 383 breathe a lot easier.

Don, are your headers smog legal?

As long as you tell the smog guy they are SLP's, or Hooker's, or Edelbrock's, then yes.

No CARB# then?

They're built by Dyno Don in a one-man shop, not by a huge company with money to spend on certification. No there is no CARB EO#.

Kevin,

Are you sure you want that kind of information to be publicly available?

Don is ok with it. Its not like we are trying to hide it. GMendoza wasnt getting it, so I had to spell it out for him. They are based on someone else's headers which are 50-state legal, so what you do with that is your business.

I will use them on an off-road vehicle that will never be operated on a public highway .

Don, can you PM me a quote for your headers & Y.

I'm glad I waited to do the Formy up. I still have my DD headers (could almost mount them on the wall as art) and the need for a Y-pipe was high up on my to-do list for parts acquisitions. This is indeed very good news, especially for dual-cat folks like me.

hi don, im interested in a set of 1-3/4 inch headers with the emmisions tubes, along with the ypipe, please let me know if you have any available. thanks.

Don, I sent you an email a few days ago regarding a purchase. I forgot to mention I do not need any emmisions tubes but I will likerly be installing an air/fuel ratio gauge. When you reply to my email please include a phone number so I can call you or if anyone here has a number for him please PM me.

Doug:
If you need shipping to a Canada address, you need to contact TDS (lonsal) here on this board.

I am not setup to ship to Canada but he is, so you can get them from him.

Don,

I mentioned in both my emails that my shipping would be to Niagara Falls NY 14303 so if you could reply with pricing today and answer my other questions I can get the order in to you tonight before I leave for 10 days.

Does anyone know how to contact Don other than by email or PM?

I ordered headers over two weeks ago and have not had any replies to any of my emails on a shipping date. It is getting close to my next race and need to prep the car.

I had assumed he would have stock but maybe that was not correct. What kind of lead time have people had on their orders?

They are not in stock. Also he can't give a firm date because he is waiting on a vendor that supplies some of the bent tubes. If you want them you'll just need to have boatloads of patience.

Lon

The headers are ready, but like Lon said I am waiting on pieces to finish the Y-pipe.
He said today......we'll see.

Thanks don I incorrectly assumed stock but a reply to my emails would have been good

Please let me know as soon as they are shippind and hopefully the transit time is short

Nice looking headers Don! Also, nice work on the y-pipe! I guess yours aren't the "long tube" right? I don't think there are advantages to the long tube style, anyway, unless I'm wrong.

Long tubes would only have an advantage if you don't have any mufflers, and short pipes behind the collectors. In his book on Small Block Chevys, John Lingenfelter made the point that all you really need on a street engine is a free flowing exhaust system. As soon as you install a cat or a muffler, you disrupt the wave energy that reslts in an exhaust system having a "tuned effect" on the engine.

Don is building an exhaust system that will give better performance than the stock manifolds and still be smog legal in California. Long tubes move the cats too far away from the exhaust ports, and are therefore illegal for use in any smog controlled car in California unless it is not licensed for the street and driven only off road. The other disadvantage to long tubes on Third Gens is that they won't fit without either reconfiguring the floor for clearance, raising the car up, or having them hit the road on any rough pavement, speed bump, etc.

I agree. Our cars are making very good power with Don's shorty headers. They are well built and free flowing. You would probably do worse with long tube headers that are not as free flowing. There is such a thing as "pumping loses".

It's not a problem at all. Remember?'s

Don, thanks for getting my shipment out. The UPS tracking number does not work. Can you please check it?

Also I will wait for the PayPal on the overpayment and please email a receipt that I can show customs.
