LS1, T56, spoon crossmember, Hawk's longtubes what to fo about Y-Pipe?
Does anyone make a Y-pipe to work with this crossmember or should I have a custom one made?

I think most folks are using the Hawk's double humped transmission mount (the Skulte original has been discontinued- Skulte has closed and moved on).

I wish spohn would make a double humped crossmember with the torque arm mount on the crossmember. Looks like the only option without hand fabricating, is hawks double hump crossmember, and BMR's trac-pack torque arm.
I have had my spohn crossmember mounted TA on my car for less than 100 miles and now I have to ditch the whole setup!

The crossmember mounted torque arm crossmember is built the same way as yours, which poses an exhaust routing issue with long tubes( which previous to my ls swap, I did not have). To make exhaust without sacrificing ground clearance, ou usually swap to a double hump crossmember for exhaust clearance. They just don't make one that has a torque arm mount on the crossmember.

Hawks makes longtube y-pipes, but I believe is only for the smaller sized headers. Even with those, most are not happy with fit and quality. You are pretty much on your own for a ypipe, but the double hump crossmember makes it MUCH easier, and gives you more ground clearance when doing so.

I did 2 1/2" y into 3". Got good ground clearance... friend who did exhaust worked at it.

Hawks makes a 2.5" Y-pipe to go with crossmembers like that. You'll have to modify it to fit your flanged headers as it is designed for slip fit collectors
