Ok so i have read through the forums and i havent seen a thread on this one yet. I have seen it for other exhausts but not for these two. I just picked up a Nismo 370 on friday. I love the car its awesome but i was thinking about getting a HKS dual Hi-power exhaust to replace the Nismo one that it came with. I was just wondering what peoples thoughts on this was? I had a HKS exhaust on my 350z and i loved it. I miss that sound on my 370z. Not that i dont like this one though. I am confused on what to do. So i welcome anyones two cents on this thanks
