Never knew this but CORSA only has 1 working exhaust outlet, my Borla on the 92 has both functional.

It's supposedly part of the Corsa's harmonic approach to canceling certain frequencies. The second outlet is there mostly for cosmetic effect.

I might go Sans Mufflers, I like the Corsa look was going to put them on the 92, but not if its restrictive......for some reason, I thought Haibeck was a Corsa fan....isn't there a comparo on his website with Corsa?

To think my 90 ran a 12.88 @112.68 with 135K miles on the CATs and a 1/2 azz exhaust, stock plenum
