Yes, our 1 7/8" are now in stock. All back orders will be shipping today. We also received another batch of 1 3/4". Both batches feature the original collectors and merge spikes. We do have about half a dozen of the 1 3/4" last batch still on hand however. If your picking up the 1 3/4", and want the new batch with merge spike please specify, other wise we will ship the last batch until they are all gone.
paradigmGT: We haven't had any returns or issues with cracking that I aware of. Its hard to tell by the picture, but if they are cracked your more than welcome to send them back for a brand new set.
Since nobody seems to want to post any dyno proven gains I will after the weekend.
SE 1 3/4 race with SE y pipe with MagnaFlow Y fabricated in place of the original SE Y
Install went very smooth with no issues, was completed in 3 hours start to finish. Removed the old manifolds and factory Y and then straight to the new SE race headers and their Y which I customized to keep the rasp down. Keep in mind I have a lift as well as a transmission jack.
Coil packs were the only item removed from the top of the engine.
The passenger side slid right in from the bottom with the removal of the starter.
The driver side didn't want to go so instead of fighting, I removed the motor mount bolt, and jacked the motor up about 1 inch with the trans jack. The header slid right in.
Painless install, will say the c5 Z06 was about the same. A little more room up top when working on the Vette.
Has anyone installed both these headers and pacesetters? If so, what was the comparison? I'm interested in these headers but not if they are significantly harder to install because I'm having a shop install them and I don't want the cost savings to be eaten up by additional labor costs.
2002Firehawk: They are around the same install time. The drivers side requires you to remove the bottom bolt on the steering arm, and swing it to the side. Passenger side slides right in. You shouldn't have to remove the starter. Both install from the bottom up.
Good to know, thanks. I'm interested in the headers+Y pipe and will place an order in the coming weeks. Just have to knock out some smaller, easier mods and then on to that.
About the gaskets - it is worth the upgrade? Spending almost $30 on something that sounds stock-ish like "GM" seems wasteful or am I mistaken?
The Multi-Layer steel gaskets are 100% worth the money. The ones we include for free are just the paper/graphite style, which have a good chance of blowing out down the road. Every personal install I have done I always bite the bullet on the steel gaskets.
Our last batch had a prototype set of merge collectors on them. We received the batch without giving the factory the ok. All in all they made the same power. However, we were just not happy with the over all design, and went back to our original collectors.

Sean,
The drivers side collector on your 1 7/8" Race versions have a problem. Wondering if you fixed it.
I already installed mine of course and they are fine...after some fancy weld work by my exhaust shop.
But the collector is angled UPWARD towards the bottom of the car. It makes it hard for the exhaust mechanic to weld a flange on the collector to make it fit without hitting the bottom of the car. Then the pipe they weld on has to be angled in a way to make the connection and then turn it downward to head towards the Y pipe.
The entire collector needs to be angled downward so it is horizontal to the ground when installed....not angled upward.
Ya, we moved the collector down around a year or so ago about 3/8" of an inch for some of the guys with tweaked chassis. Some cars are literally 1 1/2" away from the bottom of the car, and we have seen extreme cases within less than 1/8" of an inch. Just depends on how true the car is. But, yes the collector was change around a year or so ago.
So did ls6427 have an old set of these headers or should I expect problems as well? I know every car is different and I intend to do the motor mounts at the same time.
I am not sure. You should have no problems. We would have moved it down further if we heard any more issues on our end. We only moved it down in the first place because of some of extreme cases we saw. Majority of them fit just fine, including our original prototype Camaro.
