Ok so my last post was which evo should i get the ssl or se...(MR got cut after so many negitative reviews of the 6 spd tranny)

Whats the first few things i should do to it asap that needs to be done asap?

i know theres posts out there for this question but i would like to hear alot of different opinions of other people too..

boast gauge ? and is there any other gauges thats needed?

i would like for one day my evo to run 10's in the near future so im happy with my decision to get the 5 spd tranny!

What are some quick,simple,reliable setups that shouldbe done first that may help the engine or car in general last longer while increasing proformance (noticeably)?

All opinions will be considered...thanks all !!!

one more thing is there a ful exhaust thats quiet at low rpms but loud at high rpms ....that'd be great like sneaking over my gf's house without waking her parents without pushin the car in neutral...
