I love the SW downpipes and S tube catback on my Ecoboost. Turbo whistle all day long!

Volume is about the same betweent the catted downpipes and offroad and power difference is minimal, prob 3-4 horses per Stainless Works but the offroad downpipe gives a more aggressive tone and little bit more turbo whistle.
The chambered muffler catback is prob the most popular catback between the two as it's a good mix between oem quiet and the more aggressive sounding S tube. Chambered is prob most of what we sell, good tone on fireup and WOT but quiets down to near OEM levels at cruising speeds.
The S tube catback has good bit more turbo whistle and a bit louder then the chambered and def more aggressive through the whole sound / powerband.
I have a half dozen videos on youtube of my setup from idle to couple dyno pulls, search for user MasterFranchi which is my username on you tube or Ill try and link it later when not on my phone.
