Does anyone know if there is a y pipe you can buy for a third Gen ls swap with factory fbody manifolds? Muffler shops around here are shady and wont build one for me without cats. Does anyone have a usefd one for sale? I'm doing a single Turbo setup but I was throwing the idea around of putting the engine in naturally aspirated for now. My brothers going to build custom stainless headers for the Turbo system but hes busy with his project and the spring weather got me itching. I Just wanna drive this thing!

i figured by now someone would have come up with a y-pipe solution for the stock manifolds, but nothing yet. i've got a set of the 01/02 manifolds, still waiting to get my ypipe done
I'm using the 1" setback motor mount plates. reuses the old clamshell mount setup with the lsx motors.
will take the car to get tuned once everything's running; lq9 block, l92 heads, ls3 intake. should be some nice numbers

Hawk's sells three headers:
2" Stainless Works
1-3/4" Stainless Works
1-5/8" Polished Chinese made knock offs of the Stainless Works.
When the knock-off's came out, he offered a group purchase. Never said they were Stainless Works, but everyone assumed they were. So the not quite the same quality along with the initial batch having fitment problems kind of created a stink.
Unless you are running a 4.8 or 5.3, not worth the savings to get the cheaper ones.

Yes, no, sort of... It's hard to figure out unles you've read all the threads.

The recent stink up is because people ordering SSW headers often receive the knockoffs. When you contact Hawks about their mistake, they say oh, we're sorry and send the correct ones. The problem lies that Hawks does it way too often for it to be a mistake and he's preying on people not to measure the headers when they arrive
if you already have your k member setup for small block chevy mounts, hooker, heddman, trans dapt and several others make an adapter plate to use your standard mounts.

Here is a link from Thirdgen.org that has some good info some other options for headers on a thrid gen set up.

Thanks 82z28macdady,
I'm swapping an LS2 into my 89 'bird (2.8 V6 originally) and keep it CA LEGAL. Do you know if the stock pulley setup from an LS1 F-body would fit in mine? I really don't want to go out and but the March setup $$$$$$$$$.

I have the polished longtubes sold by Hawks on my car, unfortunately they're the 1 5/8" primaries but Bruce is working on getting me a set of 1 3/4" to swap out with soon. He asked me to give him a month and then call him back...
On my setup, I made 420rwhp/407 ft.lbs through those headers, it's a 6.0 with LS6 intake, MS4 cam which is 239/242 duration, 64x lift on a 111LSA, 25% underdrive crank pulley, and that's about it. Pretty good numbers.
My dad's '89 IROC-Z has an LS1 in it and he went with 4th gen shorties. There's really no reason to go with those over manifolds except for making it look more pretty. You realy only see gains when upgrading to the longtubes. Either way, the aftermarket swap lontubes, manifolds, and shorty 4th gen headers will all work with some custom y pipe craftsmanship.
