Had a shorty off road H-pipe on my fox body, and was looking to get rid of the exhaust smell that seemed to engulf the car while driving. Had these welded in and they helped out big time without a big change in sound or performance.

Had these put onto my 3.8 and it made a huge difference in sound had all four cats cut off and these welded in. Did cause the o2 sensor code to come up so may want to go ahead and invest in mil eliminators if you get these but overall very pleased with the added sound and performance will drone some on highway in case highway drone bothers you

i bought these cats about a week ago to put on my 2007 GT because the previous owner was running no cats and it sounded terrible! but once i got these in (which was a day after i ordered them!) took them to get installed, it was a relatively easy install, the guy did have to make a hole for the oxygen sensors to sit because these DO NOT have a bung for the Ox. Sensor. other then that, these make the car sound GREAT! you get that straight pipe sound but legally!
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!
