I have decided to go another route, so I have an almost new pair of Helix V2 Test Pipes for the 350z. They were used for about a month.
These also attach to your OEM brackets to prevent cracking and I have had custom o2 bungs installed. I will also include custom “non-foulers” which are gauranteed to prevent CEL/SES.
I am asking for $260 firm.
Dyno proven to give you 10whp
Definitely the best bang for the buck
Thanks,
SOLD!
