Just installed the Spohn TA with spherical rod ends, nice piece by the way, and it does fit but the clearances are very tight around the y-pipe. I have Hooker LT's connected to a 3" Flowmaster y-pipe. The y-pipe has about an 1/8" clearance on the top, (driveshaft loop), and about the same above the crossmember brace. It's going to rattle when I start my car and I'm not sure what I can do. The y-pipe was welded to the stock crossmember, something that I never did like, to keep it from hitting the driveshaft. That's not going to be a problem this time because new tranny and motor mounts lifted the engine enough so that there is more clearance.

Any ideas on what to do about the y-pipe clearance issue. I was thinking of wedging something in between the y-pipe and the brace. Maybe even a wood shim, at least then I wouldn't be listening to metal to metal contact when the engine vibrates.

 

I had the same issue. What I did was shim the cross member with washers to get more clearance.
