On 370z.com > Home they have a great review on the BERK TECHNOLOGY 370Z HFC's. The G37 & 370Z share the same engine. To get the latest developments the G37 community needs to stay on top of both platforms. They've got some comprehensive info on HFC's and exhaust fabrication. Even if you are only doing an exhaust there is some good info in there anyhow, it's a good read. Check it out! Big thank you to www.DoubleDownMotorsports.com for the editorial contribution!

Awesome find guys! A must read. Why the heck are those top bolts so hard to reach and unbolt?? I remember asking this question when my installer did my HFCs.

After reading all this, I'm confident with the right tools I also could have knocked out that job no problem.

I'll keep that in mind if I ever decide to sell the car in the super duper long distant future and have to switch back to my stock cats
