3" dual from the headers back
Does anyone make an off the shelf pair of 3" exhaust pipes I could buy so I can eliminate the Y-pipe? My Hookers have 3" collectors and run to 3" pipes into a Y-pipe,
I would like to dump the y-pipe, and run 3" pipes back to my magnaflows

Don't worry about not enough back pressure; all the tuning is done in the FL headers and collectors.
Ever notice how an engine dyno pull is setup? Mostly a set of FL headers with a realtively short section of collector-size pipe; and those people are after best overall results.
What is your engine build up?
How much expected peak HP at the crank?
Are you running cats?
What is the flow on those mufflers?

ld85,
check out my custom exhaust pics. I had a local welder fabricator weld it up.

B&B is 3-inch isnt it? I dont know if its 3" all the way for LT1s though, you could take theirs and adapt it. Either way, its not just a simple bolt-on installation.

Why not talk to Random Technology.
They have front adapters for Hookers. Their system is
3" from the collectors through an X-pipe to the cats.
While the default set-up is 2-1/2 pipe from the cats
back, perhaps they could work with you and offer 3"
pipe back from the cats?
One of the threads in this post has contact information.

To use an LTx cat back on LD85's setup you may need to have some custom work done between the header collectors and where the cats used to be (beginning of the catback). I think even cutting up the y-pipe he'll be too short to mate to a catback system.
I'd say he's probably best going to a reputable exhaust shop and getting them to put some new pipes on.
I have all the GM partnumbers for the LTx hangers and D44. Let me know if you want me to dig them up.
