I think he means he's going to leave the front part of the Y (Like, from the manifold to the mid pipe) and then go from there. That would make it practically the same thing as long as they remember to connect the 2 pipes and not divorced duals.
I don't see anything wrong with that IF that is what he means.
2005 Ford mustang V6.
18 years old. 0 accidents. 1 ticket.
The ticket was for going 27 MPH in a 25 can you believe that garbage!
I stuck it to the Man and the Man stuck it right back to me.
