Which headers?

[Corbusa]

I thought I read where a few Gents. had to shim the engine or dimple the obx headers . Correct me if I am wrong.. I too would rather support a local guy. Does anyone have the picture of Coreys headers or cost etc?

I am leaning towards purchasing the OBX headers also. I do not see why the others charge so much for LT5 headers since they are all made of the same stainless steel material.

....and there's the difference. Not the same material at all. More specific it's the thickness of the pipes that are not the same. I watch one of Corey's guys make one of their headers. It is a time intensive process.

If you are interested in Corey's headers I would encourage you to get a quote. I will say I paid much more for my SW then what Corey quoted me. Again, I was impatient.... And it cost me. However, I am 100% satisfied with my SW headers. Amazing sound and I did improve my rwhp by just under 30hp with a hot motor. Not too bad.

Hope this helps.

I looked on his webpage and could not find out about the LT5 headers.

The OBX I found out about:

1990-1995 Chevy Corvette ZR1 LT5

(2") primaries
(3") slip fitted to stock
(16) gauge runner wall
(2) o2 sensor ports
304 stainless steel
CNC Machined 3/8 inch Thick Flange
CNC machined
Mandrel bend for smoother flow
Individual port designed
Backed by OBX warranty

I'm in the process of installing a used set of mystery headers (2" primaries). Previously, I ported the intake. The intake work was probably good for a little mid range torque gain, but the headers seem to be the key to getting the big rwhp improvements in conjunction with the intake work.

Oh, yeah. I totally get that. Had my car not come with SW's I def would have gone with Corey. And he is absolutely a class guy. I thought at first you were having an issue.

Will Corey be at BG?

I like my SW headers, installed by me. Though I need to make a drive out to Corey's for a tune. It has been like 2 years since I put them on and I still haven't.

Schrade I reread your post and thought I'd add. To go along with my headers I bought dynomax mufflers #17228 and will be using the factory exhaust since its 2 3/4, It should breath just fine. I'll change out the resonator to an X pipe. and today I made some brackets for the mufflers before taking them to have the ceramic coating installed. ( I want to try and use the factory type hangers)The X pipe will be coated as well.

Welcome onto the boards there...

What work do you have in your top end there, boosted, to get the extra twist in the rear wheels???

and is header wrap beneficial?

With no portwork up top (yet), and exhaust gases not pushing capacity, the gases would cool quickly, and cooler gases are heavieir to push out the back...
