Difference in "i" and eta

[jerods87e30]

Is there a difference between the two when it comes to this particular section of the exhaust: from after the manifold to the three-bolt flange connection near the resonator

Basically the cat

??

yea, eta collects into 1 pipe right after the manifold, i is dual all the way back, with an h-pipe.

1 pipe after the manifold? I don't think mine does, mine is duel after the manifold, I definitely have an eta exhaust...

hmmm...
