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!
Had a problem with an order/quality issue. I put up a review stating so, and was contacted by Mike Linley, who was soooo nice and sooo professional, I almost felt bad about my review !! I felt the review was necessary because of bad welds/paint. Mike explained that they had a particular issue with that supplier and they had changed suppliers because of it. I must have mistakenly got an old set. (upper/lower Control arms-Foxbody). Mike asked a few questions, and was Sending me an updated replacement set while we were on the phone.!!! This is what I wish all Vendors would do; no arguments, no blame, no B.S. !! This is why LateModel stands out as an upstanding company, and backs up their products with AWESOME Customer service.
