    exhaust sound changing with mods?

    I had a 3" catback since december and love the sound of the boxer engine in my 04 wrx.

    Im finally going stage 2 and im curious if the aftermarket unequal lengthed headers, catless flex pipe up pipe and 3" catless do wn pipe will change the already low rumble of my car.

    Stupid question i know but i just want to know if the car will lose its signature sound

    Unequal length headers will retain the "rumble"
