I have Borla S-type cat back on my Durango Hellcat. Great product and sounds bad ass(at least on a hellcat). Ford ecoboost do NOT sound good ever, but this at least puts some better tips on it. I think I like the MBRP turn down tips more.
Why….they don’t sound better with anything. Leave it be or swap some tips. This is coming from a guy that has a Braptor and had a gen3 Raptor. None of the EB’s are going to sound good. I keep my stuff in quite all the time. YMMV
