terry, i was in ur position a year ago ... well heres my advice ... since i was in a position like you and i wanted mods but didn't have all the money ... the exhaust is a good choice, since u've already upgraded the air filter. after u put in an exhaust ... a full one that is ... not just cat back ... u will notice ur boost level very just slightly increasing ... only slightly ... however the main diff is how fast it reaches boost ... by 2500rpm .. feels much better ... then after that get a bleeder if u want a cheap option ... it will remove the 2 stage ... boosts much faster ... then after that consider the safc if you want moderate power like me ... under 200rwkw ... its a good option ... also consider an fmic somewhere in there as well ... i'm just happy with the stocker so i'll keep it
