Ecoboost mustang with MBRP Street 3" catback

Add to that the 1320performance catless downpipe, CVF race cooler, the intake tube via Airraid, Turbosmart DV, and some SR charge pipes. Garnish with an excellent tune from Unleashed.
Sounded awful on the first start after install but mellowed out some. Not a fan of it under WOT but it will be a lot better for the daily commute I think.
Before you ask, the drone at 65 in sixth is pretty much nonexistent. This whole system is quieter than the stock downpipe coupled with a Magnaflow street system. Like a tesla on cruise. It doesn't let itself be known until you drop the hammer.
