best exhaust system for lb7

[GTA23109a]

At what point do you all think 5" becomes necessary (or beneficial) over a 4" system??

X3 on the Banks. The 409 SS is not as flashy as the 308, but is a better material for the exhaust system.

It fit perfect on my LB7.

x4 Banks, i love my monster

Both systems start with a 4" front pipe, if a 4" exhaust wont cut it for you then your probably looking to put a hole in the hood. But that being said I liked my 5er for the sound and look.
