Curt,
Any Catback will help flow a lot better. I do believe stock is
stainless.
I have the Gibson single catback .
pros: I like the sound of the Gibson (quieter than others).
Designed for low end torque.
cons: The stainless pipes rusts. The factory rep says that the
type of stainless used will rust a little. (I think Type 416 ?)
The Gibson muffler, however, is type T-304 - no rust
(Borla, on the other hand is T-304 all the way).
Gibson Warranty - read the fine print...not too good.
Opinion: if you live in a corrosive environment (like Hawaii) and are
looking for longevity, go for stainless. I don't regret getting Gibson,
except that I was not comfortable seeing rust on stainless.
As for Torque on Bottom end - go for Gibson;
Mid to Top end - go for Borla.
My $ .02 - hope this helps....
