  Great performing
By on 10/12/2013
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.

  Great cats for a great price
By on 9/21/2013
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

  Great bang for your buck!
By on 3/4/2014
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!

Yes, I would recommend this item to a friend!

  Ready for Summer
By on 6/2/2014
I ordered these on Saturday, received them on Thursday and had them installed on the following Saturday. Passed inspection that day as well. It makes the exhaust the less raspy with no performance lost. I have a bbk o/r h-pipe, Mac mufflers and custom stainless tails. Thanks to Latemodel Restoration my GT is back on the road.

Yes, I would recommend this item to a friend!

  works excelent!!
By on 6/12/2014
I used another brand of cats and the sound of the exhaust was like the car got a flu, and the smell of the smog was still there, but i bought this couple months ago and since i installed it the smog smell went away and the exhaust sound or performance wasnt affected on my 2005 supercharged mustang gt and the price is great!

  Just what I needed
By on 3/25/2014
As stated above, just what I needed, made my car legal again, saved me from the fuel smell, and they are small so they can be tucked right into your exhaust set up without trying to find a place to fit them. Simple design, didn't change the sound much, and lighter than I expected. Thank you.

Yes, I would recommend this item to a friend!

  Excellent price!

Got an estimate for generic cats at my local muffler shop for $150 each; got these cheaper for the pair and they do an amazing job, no more gas smell (my cars a convertible!) and it's quieter on idle!

Yes, I would recommend this item to a friend!

About This Brand


Flowmaster
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!
