Hey guys,

What are my options for 1 3/4 headers? I know about the hooker super comp headers, any inexpensive shorty header options?

 

only shorties offering 1 3/4 headers are SLPs and they are not cheap

pat

 

I will soon have some more of these ready. PM me

 

Those sure look nice....I am looking forward to having a set, even more so now that I have seen them!

Bill

 

I believe ed quay makes a 1 3/4 as well as 1 7/8 headers...not inexpensive though..

 

compared to Lemons and Stahl they are a bargain at 650.00

 

Dyno Don - I have tried PM and your email both...

 

dose'nt hedman make a 1 3/4 shorty header or are they 1 5/8?

 

Dyno don, are those SLP's that are opened up at the collector?

 

No, it's a comlete new design...but similar.
3/8th thick 1 piece flanges, raised port, ball & socket collector and they don't hit the steering. (oh, they are 2 1/2" outlet)

 

Nope...1 5/8th's

 

I am close to having the Y-pipes ready for my headers.

Two models...dual and single cat.

 

Does that mean you are close to installing the headers on my car (not sure if I need the Y-pipe..)?
Bill

 

Yesterday I was at Don's shop (DynoDon) and I saw those headers and y pipes and i was impressed. This guy is genius, I wish if i bought Don's headers and y pipe instead of my SLP Tri-y

 

I have a set of Don's 1 3/4" headers on my car along with his 2 1/2" wye pipe. I have to say it is a first class set up. Making 350rwhp with a high stall converter and A4. Hoping to be making more than that in the near future. Don's exhaust is a big part of the power.

 

1989GTATransAm, are you running dual cats? Do you have SFCs, if so, what brand; I'm curious about clearance between SFCs & exhaust. Don said he could fab a set of SFCs to clear exhaust (his headers; I have Magnaflow direct fit dual cats now).
Bill

 

Yes I'm running dual cats and there is plenty of clearance. I'm also running Don's subframe connectors with no problems. With Don's sub frame connectors there are no clearance issues. I'm running a 3 1/2" exhaust pipe from the actual wye on back.

 

OK, thanks for the info, '89GTATA. I am looking forward to the new headers and SFCs. Hopefully it will be in the near future.
Bill

 

How would these headers fit together with the subframeconnectors from topdown solutions, the Alston racing ones?

 

Just fine, no issues.

 

Here is a picture of the new single cat Y-pipe to go with my headers.

 

I like the actual wye. That system should flow pretty good.

 

Will you be making more of these headers? Are you selling these? PM me.

 

JayDubb,

Where you been? I haven't heard from you in a while.

 

Whats up man!

Just working and stuff. Trying to FINALLY finish up with this SHO Taurus in my garage. Once its completed, I will begin tearing down the Camaro. Imma try to get it through emissions first and if I can, Im taking the tags off of it. I finally have pics of the 383 Im building. I had a brief moment when I wanted to build a LS1-style engine (408 inch LQ4 actually) but the prices are rediculous. Plus, I have a lot of $$$ tied up in the 383 block alone (billet caps, main girdles, lifter vally girdles, etc) and no one wanted to buy it. I am selling my HSR since Im not gonna use it anymore...

Arent you on AIM?

Sorry for the hi-jacking! LOL!

 

If you don't mind, could you tell me your source for the flanges and ball socket on the y-pipes. I've been looking all over and can't find any. I'm looking for 2 1/2 inch ball sockets with the flanges. PM me if its more appropriate. Thanks.

 

How about some pictures of them installed?

 

The flanges are found locally, and the ball socket is made on the same mandrel-bending machine that makes the headers.

Pics have been posted in this forum before, but the minimal search makes them hard to find right now.

 

I'll post some pics when I get them on Bill's car.

 

I'll be diggin' on that!
Bill

 

Don nice work I am more into race set ups. But just wanted to let you know it looks great and glad to see more options for the third gen people.

 

any longtubes don?

 

No, longtubes arent smog legal for California and we made these to pass smog. No plans to make long tubes.

 

Hey Kevin91Z, are thes street smog legal headers? If so, do they have an EO #?
I was just wondering because I plan on purchasing a set for my 91 Camaro Z28. It's got a 350 TPI motor with dual cats.

 

Here they are on Bill's motor:

No...they don't have an EO # but no one yet has had a problem.

 

Yup, looks pretty darn good to me. Great job, Dyno!
EO#? My car is an off-road vehicle that will never be operated on a public highway
Bill

 

Here's the ones after installation as requested:

 

Looks good! Can we get a shot from under the car, when the installation is complete?
Bill

 

hey Dyno Don how much do you sell those headers and y-pipe for ? also I don't need the a.i.r. tubes. Also how much would it be to ship to Port Allen, Louisiana (70767)?
----------
also no cat will be installed.

 

Yes please, a Y-pipe price for the loyal fans with the headers sitting in their garages.

 

Send a private message to Dyno Don for prices.

 

I have the Global West subframe connectors. Will there be issues with the fitment?

 

There are no issues with the headers.
Not sure on the y-pipe.

 

I'm sending a PM for prices; this is a great looking setup.

What are the specs as far as tubing? Is that y-pipe dual 2 1/2" to single 3" ?

 

Yes, 2 21/2" to 3"

 

what long tubes are illegal in california?? im glad i live in buffalo you dont even need a cat or nothing here, well technically you do but no one gives a damn thers no smog checks or nothing on '95 and lower

 

The reason long tube headers are not smog legal is not because they put out more smog than shorties, but because the law is written to say you cannot modify the location of the stock cats. And you must have the AIR tubes. With long tubes it changes the y-pipe and so it changes the cats. Its stupid but that's the way it is right now.

 

Hi!
Dyno Don can you respond to me,i have send you a personal post but still no answer.
Regards
Anders

 

I'm checking on shipping, it looks like it might be a bag of worms.

 

No problem.
Is it possible to get the y-pipe ceramic coted?
