Hi, just purchased a new nismo last Saturday. I've only driven 300 miles. The nismo exhaust isn't going to do it for me. I've been perusing the aftermarket bits and it seems there is a plethora to choose from. I read a thread discussing just adding hi flow cats to deepen the note. Will this be enough? I don't want an offensive or raucously loud system but I have trouble hearing the motor as it is and it makes me feel disconnected from the experience. Cold air intake choices seem to favor the Stillen gen3 long tube. I checked with the dealer about an oil cooler and he couldn't fine one listed. It seems to be a common complaint. Any suggestions about these or other must do upgrades. Thanks in advance for your help.
