Finally getting the Pfadt LT's
I've been waiting on these headers to come out for the C5. And with perfect timing of the yearly black Friday sale from Pfadt, my tuner and I just sent in an order for a set.
He has installed and dynoed 3 C6's, a Camaro, and a CTS-V with the new tri-y's all making between high 40's whp/tq, to high 50's and even one making 62whp!
I will be his first LS1 vehicle he does this on. I know the displacement makes for less possible tq. But still hoping for those 40's #'s at least.
My 99 is a H/C/I car with a stock exhaust. Fully ported 243's and a port matched FAST 92. The stock exhaust is really choking it up. Hoping for 420's to 430's!
Also I went with non-catted 1-3/4 size.
No idea when these will come in yet, but looking forward to seeing what they can do. I'll be sure to post results.

I've been on the fence about them too. I haven't heard any results on ls1's yet, so I'm curious to see what they do. The price is finally down far enough to were I'm thinking about ordering a set.

Looking forward to their tri-y's!
Right now with their black friday sale through the weekend, it would be the best time to order. I got most of these items last year with this deal. 15% off! Saved hundreds!

I'm going to try to scoot to Geoff's (EPS) and get a baseline done, then bring it back and see what the results are.
I went with the 1 7/8" non-catted
Our comparisons will be interesting I believe. You're H/C/I and I'll just be full bolt-ons.

Thats great! We will be some of the first to give people an idea of what they can expect with these headers on a heads and cam and non heads and cam car.

Good Lord. I'll be the first to admit, from the pics you've displayed, the welds and craftsmanship look top notch. No doubt.
One thing in curious about... Those of us (not me) that don't have the wideband yet, or not running cats... Are the plugs included for the bungs we aren't using?

Of course we do! Keep an eye out for the C5 tune we will soon include as an option to accompany the headers
