The Roush Performance Group is throttling full speed ahead with new products for Ford's new 2011 Mustang. The group recently announced a full catalog of Mustang performance and cosmetic enhancements for the new pony, and at the top of the list is a sweet sounding stainless exhaust for the 5.0L modular V8.
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. The fiberglass material used in traditional glass packs will break down over time, changing the exhaust note.
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 (part number 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 (part number 421126; requires part 420009, $175).
The Roush tips are made from 304 stainless steel and finished with a unique chrome flashing process. Standard chrome plating uses large quantities of costly chemicals, which are bonded in layers. Each layer of material has distinct properties and if a layer is scratched or punctured it can begin to crack and flake off; nowhere is this more prevalent then in high temperature applications which result in thermal expansion and can cause the plating to blister and flake off.
However, chrome flashing is bonded to the steel in a different way -- micro-porously, they call it -- with the aim of keeping a small damage from becoming a much larger one. Chrome flashing also provides heat resistance to color change, which is a major issue to unprotected stainless steel in hot environments.
Installation is quick, easy, and uses all factory hanger locations and pierce points. No modifications to the vehicle are necessary. All the Roush hangers are chromed for superior appearance and corrosion resistance. New, high quality OE-spherical clamps are included in the kit.
Roush is accepting pre-orders for the 2011 exhaust Kits by calling the Roush Customer Service line at (800) 59-Roush. These are expected to be available in early September.

While you’re listening, take a quick look at some of the other products Roush has on the 2011 5.0L menu. There’s a cold air intake (Part #420131, $225) that offers increases of as much as eight horsepower and eight foot-pounds of torque, better mileage and improved throttle response. As well, there are suspension and body kits, stripe packages and all that major Roush bling.
