Headers - Ordered - Discuss install and options

[NJ H2]

This past Sunday I ordered the Longtube Dynatech SuperMAXX SS Headers Part# 715-84110. Got a pretty smoking Deal from Auto Anything:
Regular Price: $1095.95
Discount Price: $799.99
Coupon 15% Off = $120.00
Paid $679.99 w/Free shipping!



These bolt up to my OEM exhaust/cats. I'm not coating w/ceramic inside or out nor am I wrapping them. As you see them is how I am installing. Except I did get the new upgraded botls. I ordered these with the advice from Garry:
M8-1.25 x 30mm DIN 6921 Class Class 90 Yellow Zinc Serrated Flange Bolt
From Fastenal:

Seems to be too many possible issues w/extras.
They should be here in about a week. I'll post up after the install! I'm psyched!!

When you order from Dynatech, they provide you with all of the hardware for install already; stainless bolts, stainless gaskets, everything for the full replacement, so you shouldn't need to purchase additional stuff.

For install, it will be a little complicated as you will need to work to get the old or broken off bolts out, and then get it lifted up to get those things worked up in there to bolt on. They are a little tricky, but if you are just doing headers and nothing else, shouldn't be too bad. Like I said, most of the work is getting the old bolts out and working the headers around to get them fitted up into engine area. Not sure if you are lifted or not, but it is tricky to work them in there.

Hmmm.. wouldn't want to wrap them if that causes issues. Good info! I had ceramic shorties on my Mustang and they never started looking old. They were ceramic coated.

What about a powder coat? Just to keep them looking nice? That chrome is going to color up and it will eventually look like ****.

NJ H2- that's a great deal, but won't running those into the OEM restrictive cats kind of negate most of the hard work and payoff??

Whose Gary and why did he tell you to use those bolts? I have an order at my local Fastenal I need to pick up. I'd like more info on the why's as I'll pick them up myself if it's worth it.

What about gaskets? Use the ones in the kit with some high temp or what?

I was told today, by the store I purchased my headers from, that I might need O2 extenders. Anyone know by chance? These aren't stocked locally....

I was able to confirm the OEM cat back will bolt right up.

[H2Much]

O2's will fit on the stock set up the same. I got the headers with the high flow cats and the high flow cats came with extenders to put the stock O2's in and it works fine. The gaskets are stainless and are already designed for racing high temp, same as the bolts, so you should be good with everything they send with it- Don't really understand why someone would tell you to buy different bolts and such if the one's that come with it are already high end high temp.

Either way I would suggest going with high flow cats or straight pipe anyways as you want that exhaust to keep flowing after it runs through the headers. Just my opinion, but I really do like the setup.

[pdxrealtor]

H2-- I bought the kit from OBX, not from Dynatech. Mine came with the high flow cats, not just the headers. But I don't believe it comes with the extensions.

The OBX are copies of the Dynatechs so if you needed extensions, so will I.

Still would like to hear what role the guy who said get the zinc bolts plays. Is he from Dynatech, AutoAnything, .. ??

EDIT- looks like my kit doesn't come with bolts anyways... solves that problem.

.

At first I was just going to replace the gaskets and bolts so I purchased the Fastenal replacements. Garry is a Forum member here is his post:

Then I deceided to get the Dynatechs which come with the gaskets and bolts so now I'll have extra set of bolts.
As for the high flow cats I'm going to wait and see. Auto Anything told me that most of the Headers they sell are just headers without the High Flow Cats. If I think I need em I'lll get em but after their statement I couldn't justify an additional $500. for the HF Cats when I could use that $500.00 to get a set of Ridgeds from Timmay

Thanks for posting that NJH2... it's good reading and at the same time almost makes me wish I wouldn't have got these headers. And that's assuming none of my bolts break when I try to remove them. Some of the things Easy Ed posted in that thread, about removing this to get that... geeze.

I actually called an exhaust shop for kicks and was quoted 350.00 for install. No intention on going that route but was curious.

The headers showed up today. Looks complete except no bolts. I'll grab some of those yellow zinc bolts.

I've yet to inspect them carefully....

[Hellz]

well the removal of the old bolts i woudl assume is going to be easier as you will be removing the old headers anyways.

hell, you could grind of the head of the bolts, slip the header off and WD40 the hell out of the bolt and use vicegrips or something on them. atleast then you would have more options to get at the bolt instead of just the head of it.

How did you get this pricing. Looked at there website and only see the $1099 price. Also any trick to getting the 15% coupon?

I am close to buying new headers as I have the broken bolt problem and was going to also go the OBX route but might reconsider if I could score the Dynatech's at this price.

Regardless. Great info in this post and curious how the installs all go.

If you happen to get this before midnight tonight you can use coupon code:

EJL1219

They happen to send me an email containing that code. They seemed like wheeler Dealers so if you don't get that code in time I would call them and tell them a forum member just got it for $679. w/ free delivery and maybe they will give it to you at the same price. They were delivered today and will be installed next week. I'm not gonna mess with it I'm going to have them installed by a local shop.

RE: DYNATECH HEADERS:

OK so AutoAnything told me the Dynatech Headers would bolt to my factory Cats!
They won't!

The shop doing my install called Dynatech and if you want to use Cats the factory Cats must be eliminated.
You must by the whole kit from Dynatech with High Flow Cats!

[pdxrealtor]

Why is that? Any shop should be able to cut out the factory cats, and weld them back in down the line...

X2- Cut those bitches out and weld'em in where they need to be. Anyone compitent in exhaust work can do this.

Picked up my class 90 Zink bolts today from fastenal. $50.00

Torque specs are- first pass to 11lbs, and a second to 18lbs

I will need O2 extenders. But I'm not sure how many... I though I saw 4 sensors. What kind will fit? I can't find any for hummer. Only GM and they all look different. This is a mail order deal so I want to get it right the first time.

What is the O2 socket size, can I just use a wrench? It appears so, but...

H2much ..... You out there? You mentioned jamming these in through the bottom. Is there NO WAY to install them from the top? I'm on wheel ramps or jack stands.
