any catback exhausts that give more hp?
I see a lot of people changing to aftermarket cat-back exhausts to get a deeper sound but does it give more hp for a modded truck (ie chip, 4 lb pulley, ect). What do you have, how much did it cost, and does it give more power?

This won't be exactly what you are asking for but it might help
.
My first dyno was with a 3 lb pulley, JL Ram Air, JDM chip, th/body, oil breather, and everything else stock, including the exhaust. It was done in the heat of July in South Georgia---388 rwhp and 467 rwtq. Temps in the low 90s.
I redynoed at the same shop this Feb. with a 5 lb pulley, PSP Fast Aiir, chip(two pulls--one PSP and one JL), th/body, 160* 'stat, BR7EF plugs, oil breather(3), and a JDM/Magnaflow(single muffler, #14568) c/b---400 rwhp and 487 rwtq. Temps in the high 50s.
I don't think I lost any?
