what should i expect from my new exhaust?

[Chrisbgft]

well, i am getting my 2.25" catback/no resonator and apexi n1 muffler done today. the muffler is the smaller style with the 3.5" Tip. What do u guys think? It will be angled just like the N1 catback too. What kind of performance should i expect?

ive seen a catback only bust out 10whp on a dyno chart on here somewhere.. i think it was the RS-R catback.. or something like that.
