OP make sure the Exhaust is a proven one with no drone. Most are fine (Corsa, Borla, M-Performance, etc.) On a previous build I had a custom set up which totally sucked! D-R-O-N-E central. Added a resonator and still didn't work...Tried capping off the J pipe set up rig and hated it still. Sold it , and bought a Corsa with a VRSF catted DP. Sounds pretty good actually. No vid for you but just do the research first.
