Why did Spoon made a newer version of their Spoon N1 axle back?

Is it because the new one is design to use with their b-pipe and the old one is made to use with the stock b-pipe?

Or is it because they finally realize that a full catback is better than just an axle back?

Is the older version still available after the newer one came out?

The old Spoon N1 axleback contained a significant bottleneck in the piping. They have eliminated it with the new design. No, they have not made a catback yet.

I thought there is a Spoon b-pipe available now??

There is, and their used to be. At one point it was discontinued, but its now available again.

The bottleneck is still there. Here is the new Spoon N1 flange that was cut off to remove the bottleneck. The flange measures 2" ID and is still made to bolt to a stock ITR cat back with the stock donut.



Guys, just remember, chances are if an axle back is made to bolt up to a stock B pipe it's going to have a bottleneck. The systems that get rid of the flex/donut joint are more likely not to have a bottleneck. Even the Type One B pipe has the bottleneck so it can bolt up to the stock axle back or an axle back like the Spoon N1. Here's a pic of the Type One B pipe at the axle back joint.



And with the bottle neck cut out

where is that thread that showed the Type One bottleneck removed and a new piece welded on? I think it was the Type One..could be wrong

Then what is the difference between between the old and the new Spoon N1 if the bottleneck is still there in the new one?

Seem like the new one is just looking prettier from the outside, but it is some old chit from the inside.

As far as I know, the only difference is the flange and the size of the piping. Looking at this picture:

the size of the piping seems slightly larger.... so the bottleneck is still there even with the larger one? does the ID change near the flange or something?

where can we get two 2 1/2 flange's and pipe extension for the b-pipe? I have a type one b-pipe comeing with a new spoon n1.

I believe what they did was increase the tubing from 60mm to 63.5mm. In the old design it looks like they reduced the 60mm tubing down to fit the flange that accepts the stock donut. On the new piece the 63.5mm tubing just goes over the cone of the flange and is welded to the back side of the flange, but the flange itself looks like it remains the same since it still accepts the stock donut.
