2011 GT Mustang with traditional 40 series Flowmaster Performance mufflers and "Edge-Weld" stainless 4" Tips. This GT sounds great inside and out with no drone on the interior. It comes as somewhat of a surprise to us that the standard two chamber Flowmasters were this calm however, the results were exactly what the customer wanted.

Flomasters 40 series mufflers sound better on the old push rod 5.0 V8s. For some reason the don't sound right with the OHC modular V8. The Flowmaster Outlaws actually fit the new 'Stangs.

Flowaster does not recommend 40's or super 44's. I got roush axle backs for $399.00.
