No, most people don't realize that the 3" y-pipe merger exit on any f-body Y-pipe is your first flow restriction, even on the bbk y-pipe w/2.5" tubes. If you want to maximize your hp/tq with the bbk y-pipe then replace the y-merger with a Vibrant 2.5" inlet/3.5"-4" exit. This merger fits perfect on the bbk y-pipe and give a noticeable bump in power. If you're under 500hp the 2.5" pipes on the bbk y-pipe aren't a issue.

Ya the car is bone stock as of right now besides an SLP lid and smooth bellow..... I can't see too much more being done in the future to the car but just want to do the header install once and be done and get a good quality piece that flows better for my money...

You car has minimal mods, and like you stated you dont have too much planned for the car in the future. My car is already a h/c/i LS1 and within the next 3-5 years will be a h/c/i LS2, so buying TSP's 1 7/8" now will free some hp but in the future will shine even more. Just my .02

Whatever headers you end up going with, by all means get a good 3" catback on the car. There was a thread in the General LSX forum where a guy cut open the stock muffler. You wouldn't believe the restrictions in there. Easy to see how a good flowing catback would give you 10hp.

There really isnt any fine cutoff, technically 1 7/8 header make more even on a stock motor but its only about 7hp naturally that number will increease with engine size though. To the op my BBK's literally fell in. I have installed KOOKS, PACESETTERS, AND GROATS. My bbks were by far the easiest.
1. the kooks needed the steering knuckle taken off, oil plug off and a tad bit of grinding on the k member.
2. the pacesetters needed the steering knuckle off, oil filter and plug off, the block tab cut and the k member grounded.
3.the Grots just needed the knuckle and k member ground down a bit.
4.TSP 1 7/8 I have never installed these but everyone i have seen has had to undo the motor mounts and jack the engine to one side to get them to fit.
My bbk's needed NOTHING, I left the steering knuckle in place, the oil plug in place, and never touched any part of the k member, they just slid right up and have been on the car now over 2 yrs and still dont really have any rust on them (mine are chrome finished). All the headers I have posted have good clearance once installed I would rank the bbk's and the kooks as the best but the bbks were def the easiest to instal;.
I understand your worry about the y pipe. But again think about what we are all saying if you are a stock car or lightly modded the ls1 cannot physically pump enough air to make the 3" y necessary. I mean if your catback is 3" and its only 1 pipe what good is stuffing two other 3" pipes into it going to do? The two 2.5" pipes going into the 3" catback is more than adequate. People who dyno their bbk headers get right around 25whp with a tune which is the same as other header brands.

Back on topic; I'm going to have to agree with redbird on this. For what you're looking for, per your thead title, as far as fit an install go, BBK's are probably your best bet. I've yet to see ANYONE have any issue yet.
One point I want you to keep in mind though-
I think at one point we've ALL said, "Yeah, it's just a minor bolt-on car that will never be anything else...." and before you know it you're back to scouring the classifieds for a good deal on another part. Power is addicting. Headers are a mod you WILL feel.
Final thought though. As far as saying what's the point of 2 3" pipes merging into one 3"....
You have to remember that one 3" pipe, or 2.5" is only seeing one bank of the engine. One side. Yeah, it's merging into a single 3" catback, but there's no "slamming" of anything together if your merge is worth a ****, as the TSP is, and as far as I've seen, the BBK is as well. It's all going to a 3" catback, but it isn't like you're maxing out both legs o the y pipe and tryin to cram it into a single 3" I pipe.
A 3" y will give you room to grow however.
OP, there's a lot of opinion in this thread, but the good news is there is also a lot of first hand experience. In the end, you've got to deduce what YOU want and what YOUR goals are.

I think the bbk's are what will be going in my car. I just feel that a car that is mint pristine should get the best fitting header. And the car is not going that fast anytime soon, I just want to get the best for my money and for $475 shipped with the y pipe for the coated ones, I don't see how I can go wrong.

bbk and mac are what ive been tossing around , mostly because of the 2 1/2" y-pipe , every little bit of ground clearance helps , plus keeping more low speed power , im not concerned about peak #'s
its good to know the bbks go in easy
