welcome to the club, like speedin said you should jump on tegsox's shit but if you cant then dont worry about, the n1 is in fact a loud exhaust the n/a version which isnt much of a difference from the turbo version only price but its great one at that, would be a good first starting exhaust, second your aem cai, will do exactly what you need for the moment third if your looking to get good numbers i would upgrade your valve train meaning valves, valve springs and retainers, not to mention and upgrade in the cams them selves. comp cams makes a awesome set of all cams, retainers etc, and not that bad in price eithere im looking a gett a set my self here in the next lil while.....for suspension, a set of adjustable coilovers would do the trick, skunk2 makes a pretty cheap set and there awesome from what i have been told but if your looking to get rid of gap than just do springs, i have a set of rs-r downsprings and i love them, my drop is 2" eibach, skunk2, ground countrol, tein, are just a frew that have pretty decent set ups as far as springs go, if you keep your eyes out ypou will find akll the right parts
