anybody know if the y-pipe is the same for both the 1 7/8" and 1 3/4"? I bought a set of the 1 3/4" back in the beginning of 14 and looking to upgrade to the 1 7/8". Wondering if my existing y-pipe will work.

Speed engineering, What header bolts come in the gasket kit you all sell?
Are they cheap or good bolts or studs?
Now when you say they make more power are we talking just peak hp & torque numbers or are we talking all through out the rpm range? The $50 difference between the two headers isn't a deal breaker for me I just want what's best for this car.

My 2000 SS with lid, KN filter, speed engineering 1 7/8 LTs. Ls6 intake. Put down 340/343 at 215,000 miles.
Never made less than 300 wheel torque.
Best out of the car was 12.5 with a 1.96 60' in great conditions. Is a 12.8 consistent car
a4 with 3.42

what are your guys thoughts on the whole 1 7/8" is too big for 346 cubes? I've seen mixed reviews. I'm very close to putting a set in my car and doing before and after dyno testing and track times compared to my 1 3/4" on my car in my sig.

Saw the true duals available now for Silverado, plan on buying headers and duals at same time for my truck. Any thing in the works on true dual set up for fbody? Be nice to buy 1 7/8's and true duals in one shot also.

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.
Thanks

I am considering these headers, and have read about the drivers side welded upward just like LS6427 stated in his post , would like to know how many have experienced this since the problem was supposed to be fixed, I don't mean to bring up a bad subject or be negative, I just don't want to have to deal with that problem, thanks.

Just Bought the fbody 1-7/8 header & y pipe for my sons stock lq4 swap in his 02 ws6 this past monday.
I wasnt sure which ones to get either as it may mainly stay a stock 6.0 for a long while, but you never know
May get 243s & a small cam one day and thats it.
Either way i dont think the header size is a big difference vs your pocket.
You cant go wrong with either unless you are making big power & then we all know what route you need then

wannabefastcrf: We actually have C10 LS swap headers:

YZFZ28: If we saw any additional issues we would have made a second change. They fit just fine.
AnotherWs6: Lol
LS1 pwrd NOVA: Thank you for your order. I can't remember how far from the firewall they are off the top of my head, and we don't have an F-Body on hand to take a look at unfortunately.
Thanks
