Do LPP's come in 1 7/8? I'd like to eventually get some for my blown 4wd 2500 but don't want to beat the hell out of them to fit. Do you guys think they'll clear any easier on a 2500 vs a 1500 due to them being 2" higher?

I installed two (2) sets of the 1 3/4" on 2wd NBS, but not the 1 7/8"

We had no issues at all.

Not sure why you guys are having so many problems, and I would love to take more pics if you need them...

but there has been a ton of conspiracy with these headers. I don't care, they were cheap and did me well, so far. I did have to take out my crossmember to get the y pipe in, actually, both trucks did.

Only issue I am having is with my shitty jegs band clamps, I got all sorts of exhaust leaks from those *******.

Bama, the body sits higher on the frame on 2500 models but the engine is not any higher.

I apologize, mine are 1 3/4. Here is a pic of them hitting the steering shaft on my nbs cc 4wd. It's not terrible, but as seen it rubs. I truly just need to take them off and dent them in a bit. I'll get a pic of the front diff yoke when I get home from class.

1 3/4" is much different to 1 7/8",I haven't read of anyone having problems with the 1 3/4" but haven't read anyone that installed 1 7/8" with "perfect fit" other than calspeed.
This guy also did 1 3/4"

I may just have bad luck I loosened and got everything set up several times and still it hits the front diff yoke without the clamps and bolts. I may try to loosen it all up one last time to see if I can get it to shift at all with the y, but it's not looking promising.
