I'm in touch with the VF folks. The SC itself is fantastic and runs totally fine. Love it and I'm so glad I did it. I was just looking to see if perhaps we are missing anything here that could be done or if anyone has encountered this.
From an actual emissions standpoint they state it's not emissions compliant, but all smog testing, O2 is completely legal and up to MA specs. I mention that for those that are concerned in other areas where emission testing is more difficult. This is with stock cats of course. Any x pipe will increase emissions.
