So I have a vortech supercharger on my g35 with just a Stillen cat back exhaust. I've grown quite bored with the sound (it's very mellow) and am looking to up the power aswell. I will be ordering a new pulley to up the boost but the exhaust is where I'm most concerned. I can't decide whether I should do full long tubes with a high flow car mid pipe or shorty headers and high flow car test pipes. While I want it louder I don't want it super loud because it is an Infiniti after all. I also don't want to change the tone. I want it to sound like an Infiniti and not some ricer car. Any ideas?
