Price for one exhaust adapter to bolt to the bottom of a stepdown 6 cylinder exhaust manifold is $200 plus shipping(USPO flat rate). We should have the 3/8" flanges to weld the exhaust pipes to, price later, can be shipped in same box. Sorry for any delay or confusion. Bob Parks

Got mine from Bob. Already did trial fit to a Twin H exhaust manifold. Will post pictures later today. Now I need the matching intake.

I had to replace one stud with a bolt due to the lack of room to start a nut on the stud with the adapter in place. just drilled the threads out of the original manifold and dropped a bolt in.  I also made a stainless shield to keep the exhaust out of the intake. I also removed the heat riser flapper and filled the holes with a couple short bolts. Adapter flange is at the welding shop. I decided to let the pro do the welding. I am going to use 1 7/8 exhaust pipe. It's only a 262 so I don't think dropping 1/8 ' is going to make any significant difference. I am going for the "sound" not performance. Maybe snakeing 1 7/8 pipe through the cross members will be a little easier than 2". Any suggestions on muffler choices? It's a '49 so has more room next to the fuel tank than the 51 and newer.

We put two new stainless mufflers welded together beside the gas tank, both exhaust pipes exit together under the bumper. We used 2" pipes front to rear. Thanks for the order.

Ive seen Hudson Step-down's using a muffler with dual inlet & outlets which I thought was neat but dont know the the part number.

FYI
Dual inlet & outlet Muffler is Thrush / Dynomax #17637. It has 2 1/4" in/out so a bushing is required. Cost around $40
