This picture shows the stock front section of the header to exhaust mid pipe. The front section is upstream from the resonator. What is the canister? What does it do? Why is it only on one pipe?

I've heard:

It's a resonator.
It's a silencer.
It's a NoX converter.

If any of those why only in one pipe?

No clue... I just know it's a pretty expensive piece from what I'm told (I haven't checekd the price myself). Something to do with helping reduce the harshness... and there was only room in that area for one of 'em.

So then the question becomes what happens when that piece is replaced by the pipes in the picture below the stock unit? Negative impact? Postive? Neither just louder?

The UUC Rasp X replaces that piece... and that sounds pretty nice IMHO. So I'm guessing there are no negative effects.

It's a simple resonator.

Removing it makes the rasp sound louder.
