Checked Magna Flow site two days ago and found they now list a Cat Back exhaust for the 2019 ST Part #19447 $897.Hope this makes a few more ponies and will be an definate improvement in sound .It is next on my list! And the performance parts list is getting better.
Because they're built better and sound better than most.
Nice! You won't be sorry. Borla systems sound good because they make an effort to calibrate the sound to the engine configuration. Magnaflow sound good with push-rod V8's and not so good on anything else.
