That is pretty neat, 3.5 SHO Taurus is awesome but transmission for modding the engine isn't greatest from I understand. But throw the 3.5 TT into the Mustang with RWD, stuff becomes much harder to break. Only downside in my opinion is the 3.5 ecoboost isn't a great sounding engine with exhaust. A guy by me has a SHO with exhaust and it's civic SI like.
That sucks, I defintely will not allow my car to sound like a ricer lol. The 3.7 mustang engine and the ecoboost engine are nearly identical besides a tiny bit of displacement, DI, and turbos. I'm using gt500 quad tip exhaust which has been put on a few 3.7 mustangs and it sounds pretty good, although it's no V8.
Imagine this sound with 2x the HP and twin turbo whistle....won't be bad.
