The new Ford 5.0L engine in the ‘11 Mustang is an amazing performance package. Now with the addition of the new Roush exhaust for this engine, it can also have the growl and menacing throaty bark that an American V-8 muscle car needs. Drivers will experience an aggressive sound under acceleration, yet refined under steady state or cruising conditions, without the dreaded drone inside the cabin. The Roush 2011 exhaust kit uses 409 stainless steel in the construction of the pipes and muffler and has an open-chambered design that will not deteriorate over time. There are two versions available, the difference being the shape of the tail pipe. The round tips fit the Ford or Roush Mustang rear valence (P/N 421127, suggested retail $399); the Roush square tip design gives the car a totally different look, but requires the use of the Roush rear valence. The suggested retail on the square tip kit is $440 (P/N 421126; requires part 420009, $175).
