Fahoodo!! damn you beat me to it, wanted to be the 1st GCSRT-8 owner in Bahrain!!
For the exhuast, not sure the moroor will allow you to change anything overhere, but Magnaflow makes them, besides, if i were you, i would've gotten kooks headers with high flow magnaflow cats. concerning cat-backs, there several ones out, comming and they provide similar performance, it only depends on the "dB"'s. as far as I know, Zoomers cat-back provides better performance (slightly) then others, but sounds loudest (even some guys face minimal drone sometimes). Magnaflow cat-backs are little bit less on the perfromance, loudness but cheaper than Zoomers. B&B just finished there's but its fresh, no real world tests yet.
for the CAI, all perform similarly, get the one you like most "visually". the GSM one looks clean, but MOPAR CAI frankly looks KILLER (Besides maybe behbahany or watever thats written wont consider the warrenty void for using MOPAR parts, check that).

TRUE according to an SRT Engineer (july 12th, srt10forums.com)
Lowering kit, 22"=bad for handling, braking and acceleration! (nuff said) besides dont you like you're 20's? I find them pretty huge. I would swap the tires to "Pirelli Scorpion Zero Asimmetrico"'s, (265 front, 295 rear) to little bit fill that gap. Add more comfort since the stock run-flats have hard sides. (and according to tirerack.com surveys, the Eagle RS-A isnt THAT good, its no slouch though).
No lowering kit available to date, infact the SRT-8 is already "lowered" 1" from the regualer GC
HID's, you may want to retro-fit projectors. Since I heared mixed impressions about the glare of the GC's headlight. generally it has a sharp cut.
hope that helps!
now, man did you port it to bahrain or did you buy it here? didnt see any ads for it here yet. Besides, take some shots man!
Since you did S/C you're holden (holden or lumina?) you may want to do so to the jeep! checkout GSM's S/C.
