And nonethless, my previous car, a 2008 Nismo Z, was by far the most awesome sounding vehicle I have ever heard, and I used off the shelf parts--I used generic test pipes, a magnaflow x pipe, and HKS mufflers with the stock Nismo Tips. Saved about 3k from an aftermarket exhaust and it sounded 100 times better. It droned a little bit (the interiors of the Z33 Z's are thin plastic), but that thing sounded fawking nasty using what I already had available. And it looked damn good too!
