dual catalytic converter system

Worth the effort and expense? Magnaflow #23479 setup is around $380, free shipping. I need a new cat anyway, mine was trashed due to bad valve guides and leaking injectors. Car is a 1988 and I believe that I already have the bigger exhaust manifolds since the original engine was the "F" motor. A new intermediate pipe is required as well. No luck yet finding the correct heat shield. Engine is now a 350, LT4 hotcam, vortec heads and the Scoggins-Dickey TPI base with SLP runners and a 52mm throttle body. Sounds like a good late spring project. Car has to look like it has all of the original emissions stuff for at least 5 more years.
