Question for those who installed the Doug's headers, I'm about to order a header/pipe set up, upon recommendations I'm going with ceramic coated... a few questions, first anyone have to modify or dimple for a Borgeson PS, second I'm reading drivers side tends to stick away from the car more than passenger side... anyone experience this?
thanks in advance

Now I don't have PS (stock gearbox), but it fit in perfect so no dimple! Yes, the drivers side does stick out more and you notice it while installing. But after that you don't notice it, and if you were walking by it you wouldn't notice it at all. Only you will know it does as you can't see both sides at once.
I am going Doug's ceramic with mid glass pack inserts, will install leaving original box in place to see how close and measure box size difference... dont want to fight header install.
Thanks again.

You will probably need to dimple the pipes a bit to fit the stock steering box as I found on my car. One place at the box and one place by the pittman arm. I did a trial fit and marked it with a sharpie. Hit it with a large socket and a hammer is what I had to do. Not much denting required. The chrome was not obviously damaged in my case but ceramic might be another story.

thanks, I spoke with Borgeson yesterday and he said he has heard the same but no other details, the Borgeson box is a bit larger over the stock box, I also talked with Summit and absolutely no help at all, he couldn't help with Hooker vs Dougs, chrome vs ceramic and absolutely zero information on inserts... i was surprised at the lack of knowledge in their product information support team.

The chambered exhaust gives you that deeper tone. I only have a low compression small block, but everyone thinks I have a big block!

I’m surprised you are going with the glass packs. I’ve always felt glass packs give the exhaust a “fluff” or softened tone at low rpm and a “rappy” sound under load/higher rpm.

I only settled on the glass pack insert as its the mid option and I couldn't get any info at all concerning inserts from Summit, frankly I want a deeper sound with less rap harshness... I would also prefer not crazy loud, now I'm back so searching inserts, hard to find sound bites.
thanks you, im gonna look into your recommendation

Classic Chambered vs Doug's inserts
STS baffles are another option. Definitely different in a more raspy, sharp kind of way. Sorry, I don't have a clip of those but they are out there.

Between the differences in all corvette measurements as well as the header specs some fit right in no problems and some need to be dimpled at the steering box.
I am going to install the headers with the original box then see my clearance.
