which mi-pipe for cobra?

[46cobrajm]

I want to get a new mid pipe, probably x.
I have the borla stingers and i really dont want it much louder if any than now. Im mainly worried about hp gains.
Which pipe should i get?
with or w/out cats?
and how much hp should I notice?

I would really appreciate your folks help, Im kinda of new to this but im tryin to learn.

If you want more power, it will get louder. These things scream. Get a catless X pipe and change your gearing to take advantage of the high end torque since there is no low end...
