  2. Borla Exhaust Question?

    General E46 Forum
    I have a borla cat back on my 2001 bmw 330ci, and I like the sound, but can I take out a resonator to make it louder? And If I do take out the resonator, will it be the same exhaust note as right now, only louder? Thanks you guys are the best!!
