2000WS6TARA

Alright Guys, I Need Some Input Here...i've Been An Old Car Nut For Years Now And Have Finally Given' Way To The Ecm Controlled Fuel Injection Cars Of Today. Two Years Ago I Purchased A 2000 Ws6 With Only 3,000 Miles On It. I Have Already Started A Few Mods And My Latest Bolt On Is A Bassani Stainless Steel True Dual After Cat-system I Picked Up Brand New On The Cheap !! This System Replaces The Factory Y And Bolts Directly To The Cats Using The Ball & Socket Flange. Here's My Question. Without Cutting The Pipes On The Bassani System I Do Not Believe I Have Any Header Options. Long Tubes Will Mean Cutting The Bassani Pipes And Voiding The Lifetime Warranty. I Am Not Against Block Huggers But Have Not Spoken With Anyone Who Has Installed A Set On A Late Model. Looks Like My Only Options Are To Port The Stock Exhaust Manifolds And Try To Put A High Flow Set Of Cats From Bassani Or Random Tech. Any Options Would Help.
