Dr whigam, if I remember correctly when you say "Tuned by Geoff @ EPS - 452 / 417 Retune June 20th - New #'s coming..." you are talking about retuning after your exhaust upgrades, correct? Just the headers and true duals or more than that? Not sure if anyone else is interested but I certainly am..... keep us posted.

Shameless plug- https://ls1tech.com/forums/dynamomet...ps-tune-3.html
New 42# injectors, a clutch worth a ****, and a 255 Racetronix.
I had the 42#'s last time, but one was dead, so we tuned with the stock 28.8's. this is just the final WOT tuning.
Sorry OP

Ask if they'll be willing to refund you the return shipping fee if you receive them and find the primaries to be 1-5/8". Just ensure they understand that you're asking if the entire primary is 1-3/4" and not just the inlet like they are being advertised.

Doing some perusing, it looks like Speed Daddy updated their description: Piping Diameter: 1.625"

Received my PaceSetter’s on Friday. As most of you know, these are 15g gauge mild steel rather than stainless. As one can tell from the pictures, they measure 1-3/4” primaries. The ID is impossible to get at this time as there is not a perfect spot at the flange to get a measurement as the weld needs a little “love.” Nonetheless, it measures six-hundreths less than that flanged-out eBay brands.
Just something for everyone to compare when looking at headers under $300.
No emission fittings to weld up and bungs are on the correct side:

Couldnt wait anymore huh? They look good, thanks for the pics and the info. I have plenty of other things to attend to on the old bird, so I'm going to hold off and hope that the new Speed Engineering race ones come out soon and are what they say they are. Would love to have stainless.

Nope! I decided to just go with something that was proven for now. I have confidence that Speed Engineering will make things right on the next batch, but I wanted these on before UMI's cruise in August
I'll go stainless when I need to upgrade to 1-7/8"... that will be quite some time from now, though.

I'd definitely like to know if that dpt whatever brand is 1-3/4 or not, so post up if you ordered them, Rob99z28!

Just an update. We have received confirmation that they have received our headers, and are building a test fit sample as we speak. Should be another 3-4 weeks before we have them in hand. If everything is ok, then were about 4 weeks out from that point.
Thanks
