The install is very easy and can be done before your wife gets home in the evening. This allows you to break down the shipping box and rid everything of evidence...big plus in my book!
The sounds is spot on with traditional flowmaster chambered muffles. The tips can be adjusted in regards to how far they extend past the body line of the bed. While they are not slash cut tips....they can be staggered in depth to give an appealing appearance of following the body line.
Sound level for this system is a tad higher then stock when using the factory cat system. Zero drone with that configuration.
Yes, I would recommend this item to a friend!

Love my Lightning! Wanted more agressive sound while keeping stock look as much as possible. After reviewing all the choices, I went with the Flowmaster cause downright rumbles at idle, howls on the gas. Sorry I bought a high radio/nav unit! Why pay more?
Flowmaster - The Exhaust Technology Company Flowmaster operates the only exhaust Research & Design facilities of its kind in the world, centered around the SuperFlow SF-7100 engine dynamometer complete with E.C.A. (engine cycle analysis) equipment and also SuperFlow chassis dyno's.
Through use of these dyno's, Flowmaster's engineering staff can track the complete engine cycle in millionths of a second and can obtain exact technical data of each degree of cam rotation, from induction to the tip of the exhaust system, while also showing the power numbers that really matter, the power numbers "to the ground."
Flowmaster also utilizes Spectrum Analyzers to fine "tune" the sound of each of the eleven different series of mufflers that Flowmaster currently offers, both for peak performance and just the right sound levels and tones. Flowmaster's dedication to quality is what makes them the exhaust industry leader for Latemodel Mustangs and SVT Lightnings!
