    with the down pipe it will defs get louderr i can even here my internal wastegate open sometimes(catless system) but idk about the resonator without a resonator you will probably get the common subaru droning sound on highways if you think about it you will only have one muffler if you cut out the resonator, wih is the axleback so im geusing it would be really loud

    Yes & I don't want a terribly loud car, but I want more sound than I have now.

    trust me if you keep the resonator and go with a catless down pipe your car will be louder than what it is and still sound awsome at the same time if you get the resonator cutout i think its overkill might be tooooo loud and drone too much

    Your car may be slightly louder, but at highway speeds, your car will drone a bit more than one with a resonator. The muffler will still keep the noise level down with the SPT.

    what we mean by drone is that level of sound you get when your cruising and its very deep and constant and it just annoying after a while the exhaust not tone the rumble at crusing speed is drone

    Ahhh I see. I know it's ultimately up to me, but y'all saying either keep the resonator & get a catless downpipe or get rid of the resonator & get a catted downpipe right?

    well on mine i run no more than 7300rpm on stock ej205 heads, on the ej25 engines im not to sure but i wouldnt go more than 7200rpm, if you have a stock turbo you wont get power throughout the rev range, infact alot of turbo's die off towards redline unless you have something designed and bigger for top end something like a td06 20g

    You got it backwards. Catless down pipes cause creep issues.
