I'm just trying to get some ideas on how to run dual tailpipe on a '66-earlier A-body. Seems like space is limited because of the gas tank is moved over to one side unlike the later A-bodies. Post pics if you have them. thanks

They fit but are tight. You could have a 3" single made easer. It would flow about as good as a dual 2 1/4". The "Y" pipe would make or brake (Break) the flow. A factory "Y" is not good but a "FlowMaster" type is good.

I have 2 1/4" duals on my 66 Barracuda. I only have pictures of the right side where it gets close to the tank.

Here's another view.

there's really just not alot of room under these cars..if it were me i'd run dual flowmasters: 44's are the loudest down to 50 series being quietest. then dump the pipes out in front of the tires if you really want true duals, unless you want to fight with the fuel tank. i'd think an exhaust shop could probably squeeze them out the back though.

I have duals on my 63 Valiant Convert. It was tight and the shop had a hell of a time getting it past the tank. After the forth time, he got it. I am running flowmaster 40s I believe. Its all in 2 1/4". At some point I need to add headers to the car as the stock 273 manifolds just ain't gonna cut it with the 360 going in.

A body gas tank straps went from side to side through 1967; straps changed to front-to-rear in 1968. The gas tank itself is in the same place, the frame rails are in the same place, springs are in the same place etc., etc.

I have stock Walker replacement tailpipes for a 68-up 340 on my 65 Barracuda (with 69 Barracuda tips). They fit like a glove. Unfortunately, the Walker pipes are NLA. But, basically, whatever will fit a later A will fit the early A, with a slight intrusion from the side-to-side strap which 67 A's also have. So tailpipes shouldn't be any harder to make for the early A's than for the later A's.

Thanks all! I should have looked under my '69 Barracuda before posting this question.

The early As had more room on one side of the tank because they only had single exhaust. so it is tight. but a good shop can bend around it. they also dont have the extra notch in the trans crossmember. i cut mine and welded it back in.

I got the notch taken care and actually was going to let it go with the exhaust ending at the axle but the fumes are too bad inside the car so it definitely needs tailpipes. I was thinking about dumping it out the side before the rear wheels but the muffler outlet is too far back so that would be as much trouble as tailpipes.
