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!!

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!

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

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.

This job is officially underway.

Driver side header off with no issues, except the one broken bolt head near the fire wall. Nice size stud sticking out of the head to get a grip on.

About to make sure none of the bolts break on the pass. side then I'll get out the grinder and remove the cat froward.

Been taking pics so I'll post when I'm done.

What I can say is easy easy access with wheel and wheel well liner removed.
