Down tubes / Drag pipes

Does anyone make the catless down tubes off the exhaust manifold. I bought some From Wynn a few years back but I see he disapeared?

Or can someone give me a flange size or spec for the ball & socket to attach it to the manifold so I can have a pipe made?

Thanks
Doug
 
The stock pipe is 1-5/8" up there. Most shops, when they build them will use a 2" flange and stub pipe then weld that into a larger pipe for the rest of the exhaust.

2.25" would work if you can find it.

2.5" is a pain in the arse to get it to seal properly.
 
Bought mine from Supercoupe Performance, a bit pricey but fit perfectly. Mine are 2 1/4".
