In the how to section and some other posts I've mentioned my trick.
Im running a Volant Intake with ram air, TRD S/C with URD's high boost pulley, lightweight flywheel, stock manifolds and y-pipe, 3 inch catback with Aero-turbine muffler in stock location, magnaflow resonated tip, and here's the kicker, an 18 inch magnaflow resonator welded in directly after the y-pipe to one pipe flange.
You should have heard it when it had the DTLT's. So sweet.
