Header and Mid-Section questions. Looking at the Supermaxx or LG off road systems. I am going to keep the stock muffler set up and I have installed an LS6 intake with Blackwing on my 99FRC. My questions are
1, the Supermaxx system goes into an true X cross over. Does this not negate the purpose of having a dual exhaust set-up? To me it appears that you are creating a bottleneck at this point. What are the intermediate tube sizes on this system? What are the primary lengths also.
2, The LG system only shares a small portion of the two intermediate tubes. This appears to maintian a dual exhaust path. I am concerned about the diameter of the LG's here since they are 3" and I want to keep the stock mufflers for now. Since the intermediate pipes are 3" does this effect the exhaust gas velocity? I question this since I have seen several posts say that a NA 347 motor should stay away from 1 7/8" sytems due to exhaust gas velocity.

Alot of questons I know, to me this is a big purchase that I only want to do once. I will be getting tune after the install so deleting the rear O2's is not an issue.
Thanks in advance for your time
