I had test pipes on my OEM Nismo and didn't care a whole lot for it. It was definitely louder but there was a lot of rasp and still not the level of volume I was looking for so I went to FI HFC to get rid of the rasp. Therefore I then decided to replace the Nismo exhaust with the FI exhaust and have now went with a set of GTM Res. test pipes and it's just what i wanted. I wanted loud and exotic but no rasp. heres a vid.
