These are off of my car, Hawk's 3rd gen LS1 Stainless Works headers.

1.75" primaries
2.5" collectors
no AIR

Think that's it... practically new. Only reason I'm selling is because I'm going to the 3" collector versions due to my 402ci motor and the bottle needing it. These headers made over 600RWHP with a 402 and some spray... at this point I think they are holding me back though. Also made 485RWHP NA and went 11.1 @ 126 NA so far.

New- $799

asking $725

Thanks!

I'll also throw in a 2.5" y-pipe for the same price. It worked well on my old 346" motor. It will work with the double hump "Drew" crossmember and you'll sacrifice ZERO ground clearance with it.

crossmember pics (not for sale)

 

I'll also add these to the list here...

*Sweet Thunder true duals. Custom built (by me), all mandrel bends, 2.5", pypes x-pipe, 18" sweet thunder mufflers. There is also a port welded in for a wideband o2. Also, as you can see both pipes sit on the right side of your driveshaft... well ouf of the way of your torque arm. I also ran 11.1 @ 125 with these behind my 402 so I think they flow well enough.

Here's a pic of them before I finished welding and painting them with high temp black paint.




$250 + shipping


So headers and y-pipe for $725 and shipping.

or

The whole works:
Headers, y-pipe, true duals, and band clamps for $1000 and shipping.

Of course you won't need the y-pipe and true duals but I want it all gone if possible.

*I'll also include nice stainless band clamps with either exhaust purchase. All you'd need is a LS1 3rd gen and the double hump crossmember and you'd be set!


All stuff is located in St. Louis, Missouri.

Are the headers and y-pipe still for sale? If so pm a price shipped to 52804 business address. Thanks

 

are those headers only available new in a 2.5 collector????

 

How hard is that true dual set to install? Does it just slip fit over the 2.5" Hawks Header collectors? Do you have to unbolt the headers to get it all together. I am running a similar set up with Drews Crossmember, Alston Torque Arm and Hawks Longtubes. I'm interested but it seems like it would be a very tight fit. LMK

 

The true duals just bolt right up. I custom made them for use with Hawks SW LT's, drew x-member, Alston tq arm, and great ground clearance. They are slip fit like you mentioned.

 

so do you still have the headers?
