I've been doing the research on this, and just have a couple questions for confirmation:

1. The Roush exhaust is just a Borla system with the Roush name on it correct?

2. Would the "legal" Roush exhaust system be the clone of the Borla system, or would the "off road" system be the clone in regards to exhaust note?

Thanks in advance

 

I don't know, but what has your research come up with?
