Hey guys so let me start by saying I recently purchased a Greddy Axle Back for my G35 coupe 2004 i recently removed my resonator from my midpipe cause i want that growl sound that our gs have problem is when i go up to 3k- and above theres a nasty rasp.

Also leaving the mid pipe resonator on gives the car a little deeper tone but not as deep.

Im looking for some advice into maybe getting my car too a level where i would want to amplify the sound without giving me any rasp heres a few videos

Greddy Sp2 Muffler Oem midpipe oem y pipe berks hfc


Mods are same as above only I removed the resonator from the mid pipe


Overall in the beginning I like that it gives me a little deep tone but its not loud enough in the 2nd video it the type of sound i want but the rasp messes it all up..is there anything you guys you think would help me perhaps a smaller resonator than the coupe's Oem Mid pipe...any ideas or advices?
