Most stock exhaust can handle almost 500hp and high torque ranges from what I have learned. It's a tweaking game at best with your programmer, to pull out the powa!
totally true...an exhaust system in itself almost requires constant upgrading especially as anyone mods up. it took alot of tweaking before i was totally satisfied with my setup..

No tuner yet, looking at Cortex. Those are the mods in the sig, nothing more. Stock Hemi SPort, 3.92 rear.

Well, there are the window vent shades and fiberglass cover, but I don't think that one counts here.

Default True dull x pipe inner diam size?

Ive checked there are different inner sizes. At this point its 2 exhaust headers 2 1/2" diam going in to a 3" y so should the inner diam of the x pipe be 3 1/2, 3 3/4, 4, 4 1/4, 4 1/2 and so on?
