im officially picking my car up June 2nd and i ordered it already with the GMPP exhaust but i was thinking of putting the intake on as well when it comes so i have what i want and its all good with the warranty any ideas on about how much of a gain id be getting with the two? im not looking for something ridiculously fast just something fun to drive as a first car(ive worked years for this) and something i can slap the civic kids around with

 

Intake around 3hp and exhaust could be around 8-10 HP.(At the crank)

My guess.

 

Maybe 10 more horses total, I really can't tell a differance.
