Berk TPs on 2015 Nismo with stock Nismo catback

Duncanz

I've seen several posts about test pipes and thought I would provide my impression of the Berk non res test pipes with my 2015 Nismo while I still have the stock catback. I was concerned about two things, noise and the demon bolt. I'm happy to report that since my car only has 1300 miles and that I used many comments from this site pertaining to the demon bolt that I had zero issues removing any of the bolts. Also the sound level increase is barely noticeable, so little so that my wife didn't make any comments. It does have a rasp at around 3500 rpm. No dyno numbers but the combined weight loss is 12lbs for what that is worth. Only about 150 miles on the upgrade but to date no CELs.

Couple of notes: my nismo only has 1300 miles and it's not a daily driver.
